1. Introduction
The reconstruction of the Gospel of Marcion has come under renewed scrutiny. To what extent was Marcion (d. 160) himself responsible for the Gospel? Was this Gospel a catalyst for the composition and redaction of the other Gospels?Footnote 1 Did it serve as a source not only for Luke but also for other early Gospels?Footnote 2 Such provocative questions have enlivened the debate surrounding Marcion's Gospel and its implication for New Testament textual criticism.Footnote 3 Several reconstructions of Marcion's Gospel have appeared since 2013,Footnote 4 building upon the monumental work of Adolf von Harnack almost a century ago.Footnote 5 Since polemical works form the primary witnesses to Marcion's activities, a thorough analysis of these sources forms a necessary foundation for any reconstruction of his writings and thought.Footnote 6
The present article offers a new analysis of an enigmatic source used to reconstruct Marcion's Gospel and thought: a Syriac quotation found in the fragmentary manuscript London, British Library, Add. 17215 (fols. 30–3). This quotation states that Jesus ‘came down and appeared between Jerusalem and Jericho’.Footnote 7 Some have taken the quotation as evidence for the opening of Marcion's Gospel, which, like Luke 4.31, uses the language of ‘coming down’ (from Greek κατέρχεσθαι). Others have understood it as an allegorical interpretation of the Parable of the Good Samaritan, which also mentions Jerusalem and Jericho (Luke 10.30), and suggested that it derives from Marcion's Antitheses or the teachings of the Marcionites. There remains much uncertainty regarding the relationship of this quotation to the writings attributed to Marcion.
The first step in either affirming or rejecting the relevance of this quotation for the investigation of Marcion must be a thorough understanding of the text in which it appears. To this end, the present article first examines the various strands of scholarship on the quotation (section 2). The survey of scholarship reveals divergent views on the quotation's utility for reconstructing Marcion's Gospel. It also shows that, despite the use of this quotation for over a century, no study has returned to the original Syriac text since 1893. The remainder of the article offers a new analysis of the quotation, identifying the anonymous source as a letter by the Syriac author Jacob of Serugh (d. 520/1), contextualising the quotation within this letter and providing preliminary reflections on its relevance for research on Marcion (section 3). As a whole, the present study seeks to offer a foundation for further studies of this quotation as a source for Marcion's Gospel and thought.
2. The Anonymous Syriac Source and the Study of Marcion
In the mid-nineteenth century, a fragmentary Syriac manuscript arrived in London that contained a short quotation attributed to Marcion. An English translation of part of this manuscript appeared within a few decades that has been quoted in subsequent studies on Marcion up to the present. Scholarly assessments of its position within Marcion's corpus can be categorised as follows: (1) seeing it merely as reflective of Marcion's or his followers' teachings; (2) viewing it as evidence for Marcion's Gospel; and (3) considering it irrelevant due to its irreconcilability with other sources for Marcion's Gospel. A brief history of scholarship on this quotation will both reveal the major points in favour of and against each approach and expose the thin evidentiary base on which these arguments have been constructed.
In 1845, the British Orientalist William Cureton commissioned Auguste Pacho to purchase manuscripts for the British Museum from the Monastery of the Syrians in Wadi al-Natrun, Egypt. The manuscripts arrived in London in 1847, and William Wright published a catalogue of the collection of Syriac manuscripts in the British Museum (now held in the British Library) from 1870 to 1872.Footnote 8 Here he describes a fragmentary manuscript consisting of four folios that now has the reference number British Library, Add. 17215 (fol. 30–3; see Fig. 1):
Four vellum leaves, all more or less stained and torn, written in a good hand of the viith or viiith cent., with from 22 to 28 lines in each page They formed part of a theological treatise. The heresies of Marcion, Mani, and Bardesanes, are discussed on the first leaf, and the Gospel of the Hebrews is mentioned, . [‘The account of Matthew which was for the Hebrews.’]
The greater part of the writing on the verso of the last leaf has been effaced, to make room for the concluding words of the Gospel of S. Mark, ch. xvi. 19, 20.Footnote 9
My own palaeographic analysis has suggested that the portion of the manuscript relevant for the present study could date to anytime between the late seventh and the ninth century.Footnote 10 But Wright's description remains in general reliable. His sketch of the contents of the manuscript applies only to folios 30 and 33 (the first and last leaves). The catalogue entry appears in a section on anonymous theological works, and the reference to Marcion here would shortly inspire much interest in the contents of this manuscript.

About two decades after Wright published his description of this manuscript, William Emery Barnes issued a brief notice on the manuscript in the 21 October 1893 issue of The Academy, a weekly review of literature, science and art based in London. The opening section highlights the potential interest this fragment may hold for readers:
I venture to think that the enclosed translation from a Syriac MS. in the British Museum may prove interesting to some readers of the Academy. Dr. Wright, in his Catalogue, assigns the MS. to the seventh century, and says that it contains a reference to the Gospel according to the Hebrews. I do not think that the reference to the apocryphal Gospel is probable; but the fragment is still interesting, from the statement attributed to Marcion that our Lord first appeared in human form between Jerusalem and Jericho. Can anyone illustrate this statement, or suggest a probable author for the fragment?
The pages of the MS. are injured, especially at the top. It is a mere fragment, bound up with other fragments. I showed it to Prof. Bensly during his last visit to the Museum.Footnote 11 He said at once that it was ‘ancient,’ and turned from his MS. of the Peshito to read the word ‘nkheth’ (came down) for me.Footnote 12
After these introductory words, Barnes provides a translation of the recto and verso sides of the first folio (fol. 30). This includes the quotation of Marcion to which he had alluded:
… Marcion … said that our Lord was not born of a woman, but stole the place of the Creator and came down and appeared first between Jerusalem and Jericho, like a son of man in form and in image and in likeness, yet without our body. And he in no wise brings the history of the Blessed Mary into his teaching, and does not confess that he received a body from her and appeared in flesh, as the Holy Scriptures teach.Footnote 13
Barnes assumed that the phrase ‘between Jerusalem and Jericho’ originated with Marcion and highlighted this part of the quotation with italics. This point would spark controversy as the known quotations of the opening of Marcion's Gospel contain language of ‘coming down’ but do not refer to Jerusalem and Jericho.
Theodor Zahn published at least three studies of this fragment after encountering the English translation in Barnes’ article. In 1896, he briefly discussed the discovery of the fragment and argued that Marcion could not have written that Christ ‘came down and appeared between Jerusalem and Jericho’. This would not fit with what was known of Marcion's Gospel from one of Tertullian's (d. after 220) works,Footnote 14 which seems to suggest that the opening of Marcion's Gospel referred to Jesus coming down in Capernaum (see Luke 4.31).Footnote 15 Zahn repeated the same argument about the incompatibility of the Syriac source with Tertullian in another work in 1907.Footnote 16
Zahn's most comprehensive treatment of the fragment appeared in the Neue kirchliche Zeitschrift in 1910.Footnote 17 Here he seeks to answer the two questions posed by Barnes: ‘Can anyone illustrate this statement, or suggest a probable author for the fragment?’Footnote 18 Zahn admits that he can only provide a partial answer to the second question about the authorship, suggesting that the source is probably an anti-heretical writing such as that of Eznik of Kołb (fl. 429–50).Footnote 19 But he offers a much deeper investigation of the first question regarding how this fragment fits into Marcion's thought. After translating Barnes’ English translation into German,Footnote 20 he develops his argument as follows. The only really new aspect of this Syriac source, Zahn maintains, is the statement that Christ appeared between Jerusalem and Jericho.Footnote 21 Since this cannot refer to the beginning of Marcion's Gospel, which consists of Luke 3.1 and 4.31, it must allude to another biblical passage. The quotation could well come from Marcion's Antitheses or, more likely, from another anti-heretical work that quotes the Antitheses.Footnote 22 In a further step, Zahn proposes that the quotation reflects an elaboration of the Parable of the Good Samaritan, in which both Jerusalem and Jericho are mentioned (Luke 10.30). Since Christ was often interpreted as the Good Samaritan, Marcion may have incorporated this parable into his teaching about Christ's appearance.Footnote 23 Zahn's interpretation of this quotation as reflective of Marcion's teaching and perhaps derived from his Antitheses forms one influential approach to this anonymous Syriac source. Like all who followed him, Zahn did not consult the original Syriac text but relied on the English translation found in Barnes.
The next substantial discussion of the anonymous Syriac source came with Adolf von Harnack's monumental treatment of Marcion.Footnote 24 In the first edition from 1921, Harnack reconstructs the Gospel's opening line as follows: ‘[Luke 3.1a] In the fifteenth year of Emperor Tiberius, at the time of Pilate, [Luke 4.31] Jesus (Christ?) descended (from heaven?) to Capernaum, (a city of Galilee [of Judea]?) and was teaching (them?) in the synagogue.’Footnote 25 In the extended apparatus, he lists the various witnesses to the beginning of the Gospel and includes the following quotation from the English translation of the anonymous Syriac source:
Marcion said, that our Lord was not born of woman, but stole the place of the creator and cam [sic] down and appeared first between Ierusalem and Iericho, like a son of man in form and in image and in likeness, yet without our body.Footnote 26
Harnack cites the quotation as found in Barnes's article, but modifies the orthography and removes the uncertainty about the opening words. One brief comment on the source follows the quotation: ‘I have not been able to determine where the information that Jesus first appeared between Jerusalem and Jericho originates.’Footnote 27 He suggests in a later part of the study that the anonymous Syriac author may have been Ephrem the Syrian (d. 373).Footnote 28
A review of Harnack's work published in 1922 criticised his use of the anonymous Syriac source as insufficiently founded.Footnote 29 Nevertheless, Harnack included the source in the second edition from 1924 without further comment.Footnote 30 Harnack's incorporation of this quotation into the apparatus to his reconstruction of Marcion's Gospel forms a second approach to the quotation: taking it as a possible witness to the opening of Marcion's Gospel. But like Zahn, Harnack based his use of the source only upon the English translation found in Barnes’ article. His study did not represent a new investigation of the Syriac text.
Over the remainder of the twentieth century, the anonymous Syriac source primarily attracted attention in investigations of early exegesis of the Parable of the Good Samaritan. In 1967, Werner Monselewski pointed to the anonymous Syriac source as a potential witness to an early interpretation of the parable.Footnote 31 After quoting Zahn's German translation of the passage, he points out a parallel between the rejection of Christ's embodiment from Mary in the quotation and a Greek fragment of one of Origen's (d. 253/5) homilies that refers to an interpretation of the Samaritan ‘as Christ who bore the flesh from Mary’.Footnote 32 Monselewski further argues that Origen's homily has an underlying anti-docetic, and thus an anti-Marcionite, perspective. To this end, he identifies certain parallels with Tertullian's anti-Marcionite polemic and defends the authenticity of the quotation as reflective of Marcion's thought.
The reception of Monselewski's arguments proved mixed. In 1972, Antonio Orbe followed Monselewski by assuming the authenticity of the quotation. He offered a Spanish translation of the quotation,Footnote 33 and identified a wide range of parallels in second-century writings on the Good Samaritan.Footnote 34 But in 1978, Giulia Sfameni Gasparro argued against Monselewski's conclusion that the anti-docetic tendencies of the Greek fragment should be attributed to Origen.Footnote 35 After offering an Italian translation of the quotation based upon Zahn,Footnote 36 she suggests that the anonymous author probably did not have access to Marcion's own works, given the difference between the quotation in this source and the opening of Marcion's Gospel. She concludes: ‘Therefore, the Syriac polemicist would have recorded not the original doctrine of Marcion but the creed of contemporaneous Marcionites.’Footnote 37 The teachings found in the quotation are, as she emphasises, a common part of the Marcionite patrimony.
A further study of the anonymous Syriac source related to the Parable of the Good Samaritan appeared in 2004.Footnote 38 Riemer Roukema first offers a translation of Marcion's quotation into English based, again, upon Zahn.Footnote 39 He then summarises the various opinions on whether this supposed quotation should be seen as an authentic teaching by Marcion from his Antitheses. Roukema concludes that Marcion's teaching that Jesus first came down from heaven to Capernaum cannot be harmonised with the quotation in the anonymous Syriac source. Moreover, Marcion's rejection of allegorical interpretation in general would not support an interpretation of Jesus as the Samaritan.Footnote 40 A summary of Roukema's article appears in Joseph Tyson's monograph on Marcion and Luke-Acts,Footnote 41 and at least one recent biblical commentary mentions the quotation – both in relation to the Parable of the Good Samaritan.Footnote 42 But Roukema's article forms the last publication known to me that takes up Zahn's approach to the quotation as an authentic source for Marcion's thought or his Antitheses.
In addition to Zahn's and Harnack's use of the quotation, a third approach emerged in studies regarding the reconstruction of Marcion's Gospel. As the inadequacy of Harnack's reconstruction became apparent, calls for a more methodologically rigorous approach to the sources for its reconstruction emerged.Footnote 43 Two new editions of Marcion's Gospel appeared in the 1980s and 1990s, and both editors decided to focus on a more limited range of sources, thus eliminating the need to consult the anonymous Syriac source.Footnote 44
In the wake of questions that arose about Marcion's role as editor of the biblical text and the relationship of his Gospel to the four canonical Gospels,Footnote 45 several new reconstructions of the Gospel have been published in the last ten years. The editors of two of these editions explain their use of different sources for reconstructing the Gospel. Jason BeDuhn includes some of the minor sources in his study,Footnote 46 and he commends the use of such sources in a more recent article.Footnote 47 He does not, however, attend to the anonymous Syriac source in his reconstruction of the Gospel. In the first edition of his reconstruction, Matthias Klinghardt concludes that the minor sources are too scattered and uncertain to use for reconstructing the text of the Gospel and only regards using them as appropriate when they complement the three main sources of Tertullian, the Adamantius Dialogue and Epiphanius of Salamis (d. 403).Footnote 48 Responding to criticism on this point, the second edition incorporates several additional minor sources but the anonymous Syriac source is not among them.Footnote 49 Two other new reconstructions of Marcion's Gospel do not comment on this source.Footnote 50 The similarity in the language of ‘coming down’ in the opening of Marcion's Gospel and the anonymous Syriac source seems to have convinced Harnack of the relevance of this quotation as a witness to the Gospel. It did not persuade all of his followers, who took a third approach to this source by excluding it from their studies.
In his reconstruction of the Gospel from 2015, Dieter Roth takes a different approach by incorporating the anonymous Syriac source. In fact, Roth attends to all three major and fifteen minor sources used to reconstruct Marcion's Gospel.Footnote 51 He mentions the anonymous Syriac source as a witness to the opening of Marcion's Gospel, citing Roukema's translation of the passage. Roth agrees with Roukema's conclusion that this is probably an allusion to the allegorical reading of the Parable of the Good Samaritan in which Jesus is understood as the Samaritan. Since the passage is not attested elsewhere, he concludes that it is doubtful whether the passage preserves a statement of Marcion and that it should only be used with utmost caution.Footnote 52 In this way, Roth reflects the approach taken to the source by Harnack by including it as a possible source for Marcion's Gospel but not letting it influence his reconstruction of the text.
In summary, scholarship on Marcion has taken several different approaches to the anonymous Syriac source. Zahn initiated a trajectory of seeing it as an authentic teaching of Marcion, perhaps reflective of the content of his Antitheses. Harnack drew attention to the similarity of the language found in this quotation to the opening of Marcion's Gospel. Later reconstructions of the Gospel either excluded this source or recommended using it only with extreme caution. Despite a good number of studies that incorporate the source into their research on Marcion, no publication known to me has engaged with the original Syriac text since 1893. Indeed, there are several secondary and tertiary translations of the quotation: Zahn based his German translation upon Barnes’ English article; later studies translated Zahn's German into Italian or English. The only recent reconstruction of Marcion's Gospel that takes this source into account takes over an English translation based upon Zahn, which itself was based on Barnes’ English article.Footnote 53 Here we are at four levels removed from the original Syriac, with two English translations in between. A return to the Syriac source itself is thus a major desideratum in order to clarify what importance this source may hold for research on Marcion.
3. A Quotation of Marcion in a Letter of Jacob of Serugh
This section offers a fresh analysis of the Syriac manuscript in which the quotation attributed to Marcion appears. After identifying the source as a letter of the Syriac author Jacob of Serugh, I will describe the literary context in which this quotation is found. This will lead to three preliminary remarks on the relationship between the quotation and the study of Marcion. An ultimate judgement about whether this source should be incorporated into investigations of Marcion's Gospel and thought seems, on my view, best reserved for a more extensive study that can put it into conversation with a wider range of sources. The observations offered here are meant to serve as a foundation for future research.
Although the text in British Library, Add. 17215 has been known as an anonymous Syriac source for over a century, the identification of the text is actually quite clear. My original examination of the Syriac text has uncovered that the quotation attributed to Marcion appears in a known letter of the Syriac author Jacob of Serugh, specifically Letter 23.Footnote 54 The three folios that preserve portions of Letter 23 correspond to the following sections of the critical edition of Jacob's epistolary corpus:
Folio 30r: Olinder, Epistulae, 201.1–22
Folio 30v: Olinder, Epistulae, 201.23–202.13
Folio 31r: Olinder, Epistulae, 183.7–29
Folio 31v: Olinder, Epistulae, 184.5–27
Folio 32r: Olinder, Epistulae, 185.1–27
Folio 32v: Olinder, Epistulae, 186.2–26
As this summary of the contents makes clear, the current order of the folios would not have corresponded to the original manuscript. Folios 31 and 32 directly follow one another, while folio 30 would have appeared later in the manuscript. Folio 33 contains fragments from a work attributed to Gregory Thaumaturgas (d. ca 270) that only survives in Syriac.Footnote 55
Now that we have identified the text from which this quotation derives, a brief description of its author and an analysis of its contents are in order. Born in the mid-fifth century, Jacob received his education in the city of Edessa (Şanlıurfa, Turkey) at a time where Greek exegetical works were being translated into Syriac.Footnote 56 By the early sixth century, he had risen to the ecclesiastical rank of periodeutēs, assuming some of the functions of a bishop in rural areas. In 518 or 519, he became the bishop of Batnae of Serugh (Suruç, Turkey) and died shortly thereafter in 520 or 521. Jacob's surviving corpus forms one of the largest in the Syriac tradition, including over 300 homilies and forty-two letters by him as well as a letter addressed to him.Footnote 57 His writings discuss a wide range of topics, but the majority of his homilies and a good number of his letters focus on biblical exegesis. This is also the case with Letter 23, which is the largest letter in his corpus, covering around thirty-five pages in the critical edition.
Jacob addressed this letter to a Greek-speaking ecclesiastical leader named Maron from the city of Anazarbus (Anavarza, Turkey) who had the rank of lector.Footnote 58 Maron had written a letter with a list of questions on difficulties in the biblical text. On the basis of Jacob's reply, it appears that Maron did not originally address his letter to Jacob but it reached him through others.Footnote 59 The letter had to be translated from Greek to Syriac before Jacob could respond, and he alludes at one point to the differences between the Greek and Syriac biblical texts.Footnote 60 Jacob's letter is organised around six questions on biblical exegesis:
1. On how God is said to have rested on the seventh day (Gen 2.2–3);Footnote 61
2. On Noah's age when the flood came (Gen 7.6);Footnote 62
3. On the duration of time that Abraham's seed would be subjugated (Gen 15.13);Footnote 63
4. On the bread of the presence that the priest Ahimelech gave David (1 Sam 21.3–6);Footnote 64
5. On God's regret for making Adam and for crowning Saul king (Gen 6.6; 1 Sam 15.11);Footnote 65 and
6. On the differences in the genealogies of Jesus (Matt 1.1–16; Luke 3.23–8).Footnote 66
The quotation of Marcion appears in Jacob's response to Maron's sixth question, which addresses the differences in the genealogies of Jesus found in the Gospels.
Jacob responds to Maron's question about the genealogies in two different ways. First, he points to the audiences of the accounts: Matthew wrote to the Hebrews, Luke to the gentiles.Footnote 67 Thus, Matthew started his genealogy with Abraham, while Luke traced it back to Adam to include all of humanity.Footnote 68 Jacob's second approach consists of a theological reading of the genealogy in Luke. He argues that this genealogy served as proof of the incarnation of Christ. This section immediately precedes the section of the letter translated by Barnes and merits quoting in full:

Two aspects of this passage stand out. First, Jacob's argument focuses on the incarnation and for this reason invokes the heretical trio of Marcion, Mani (d. ca 276) and Bardaiṣan (d. 222). Second, he attributes the same view to the three of them, suggesting that they each share the same perspective on the incarnation.
The passage that follows has been translated by Barnes as cited above, but deserves a fresh translation based upon the critical edition and the text in British Library, Add. 17215:

This quotation of Marcion appears in a new light when put in its context. Each of the quotations from the three maligned teachers relates to the overarching topic of the incarnation. The quotation attributed to Marcion denies the incarnation and offers an alternative explanation for Christ's appearance. The quotations attributed to Mani and Bardaiṣan disparage the body as something unworthy. The remainder of Jacob's response turns away from the polemic and seeks to use the genealogies themselves to demonstrate the incarnation. His discussion of Marcion, Mani and Bardaiṣan has effectively ended here.
We have now both identified the source from which the quotation attributed to Marcion derives and examined the context in which it appears. What might this tell us about the relevance of the quotation for the study of Marcion's Gospel or thought? Here I will offer three preliminary remarks in this regard.
First, an analysis of the letter offers one basis for determining whether Jacob of Serugh manipulated the quotation. As Zahn pointed out over a hundred years ago, the reference to the Lord appearing between Jerusalem and Jericho forms the major novelty in this quotation. While each of these locations appears elsewhere in Jacob's letter,Footnote 73 neither recurs in Jacob's discussion of the genealogies. In short, there was no reason for Jacob to mention these places other than to elucidate Marcion's thought. On the other hand, Jacob's response to this question centres around the doctrine of the incarnation. Just before the quotation attributed to Marcion, he assigns the same general teaching to all three maligned teachers as follows: ‘He did not come in the flesh, nor did he become incarnate with a body of the house of Adam.’ The inclusion of statements such as ‘our Lord was not born from a woman’ and ‘for he did not have a body’ in the quotation attributed to Marcion served Jacob's argument well. While the reference to Jerusalem and Jericho does not seem suspect, the description of Marcion's views on the incarnation reflects polemical discourse against him and is less likely to be reliable.Footnote 74
Second, Marcion's quotation can now be investigated as a part of the Syriac heresiological tradition. Zahn suggested that the quotation probably belongs to a heresiological work such as that of Eznik of Kołb, while Harnack had suggested that the author may have been Ephrem. We can now confidently attribute this quotation to an author who belonged to the learned Syriac cultural circles of the late fifth and early sixth centuries. It should thus be interpreted as a part of the Syriac heresiological tradition in which Marcion, Mani and Bardaiṣan played important roles.Footnote 75 Jacob himself lists the three of them together in one of his christologically focused letters.Footnote 76 He may well have inherited the polemic against Marcion found in Letter 23 from another source. Further, if one wishes to take the attribution of the quotation to Marcion seriously, one should consider the process of transmission from Greek to Syriac. In his review of recent reconstructions of Marcion's text, BeDuhn criticised Roth for his silence ‘on the method by which he derives Greek text from non-Greek sources’. He argued that one must investigate ‘the possible Greek variants that might lurk behind a Latin or Syriac or Armenian translation’.Footnote 77 With the knowledge that the present quotation appears in a Syriac work, one could begin to consider what Greek text – beyond the phrase ‘came down’ – may have stood behind the Syriac text.
Third and finally, Jacob's quotation of this passage in the context of a question regarding the genealogies of Matthew and Luke could be significant for an investigation of Marcion's Gospel and the polemic against him. As the previous section has shown, the phrase ‘came down’ prompted Harnack to associate the passage with Luke 4.31 and thus the beginning of Marcion's Gospel. According to Epiphanius, Marcion's Gospel did not include a genealogy of Jesus.Footnote 78 The letter's reference to Marcion's omission of ‘the history of the Blessed Mary … as the Holy Scriptures teach’ could form an additional connection to the same place in Epiphanius’ work, which mentions the lack of an account of ‘the angel proclaiming the good news to the virgin Mary’.Footnote 79 It would be a stretch to consider this as evidence that Jacob himself was directly familiar with Marcion's Gospel. It does, however, at least seem plausible that a polemical tradition against Marcion connected the lack of a genealogy in his Gospel with a criticism of his view on the incarnation.
These three observations are meant as a potential starting point for a more detailed investigation of the witness of this quotation to Marcion's Gospel or his thought. Here we have briefly evaluated the extent to which the quotation may have been contrived, how one should attend to the fact that it survives only in Syriac, and finally the provocative correlation between the lack of a genealogy in Marcion's Gospel and Jacob's invocation of this quotation in a discussion of the genealogies. These brief reflections have thus highlighted caveats for working with Jacob's letter and identified a few points of reference for its integration into research on Marcion and the heresiological discourse surrounding him and his followers.
4. Conclusion
This article has investigated the origin of a quotation regularly cited for reconstructing Marcion's Gospel and understanding his thought. The identification of Jacob of Serugh's letter to Maron as the source of the quotation offers a much stronger foundation for considering its potential relevance for research on Marcion and the discourse surrounding him. Scholars may ultimately conclude that Jacob of Serugh's letter to Maron does not contain a quotation of Marcion worth considering in investigations of his Gospel or his thought. It may rather prove useful only for the study of the development of the rhetoric used against Marcion. Either would be a welcome outcome of the present study. If scholars working on Marcion are now in a better position to evaluate this quotation, the principal goal of the present article has been achieved.
The examination of the history of scholarship regarding this quotation in the second section proves perhaps just as relevant. The survey exposed several shortcomings in the study of Marcion's Gospel and thought. Scholars who have reconstructed the Gospel, from Harnack to the present, have expressed due caution when using such minor sources, and hesitancy regarding the quotation attributed to Marcion in Jacob's letter seems justified. Yet, as my research has shown, no one has commented upon the original Syriac text since 1893. This means that evaluations of this quotation – whether correct or not – have not been based on a thorough investigation of the source itself.
In a recent discussion of the state of research on Marcion, Winrich Löhr remarks that it may be prudent for the time being to separate the study of Marcion as an editor of the Bible from the investigation of Marcion as a Christian teacher.Footnote 80 The quotation of Marcion from the letter of Jacob of Serugh is an interesting text that stands somewhere in between these two areas of research. At the very least, Jacob seems familiar with a polemical tradition that criticised Marcion's teaching on the incarnation. This tradition may well have associated his views on the incarnation with the lack of a genealogy – and perhaps Marian content – in the beginning of his Gospel. In this way, Jacob of Serugh's letter would stand in a long tradition of criticising Marcion's teachings by referring to the text of his Gospel.Footnote 81
