In October 2022, the Church of England commissioned a study of the likely impacts of allowing the blessing or marriage of same-sex couples in church. This paper reports on a survey of key informers (bishops or chief executive officers) in dioceses in the seven provinces of the Anglican Communion that had at that time allowed either same-sex blessings (SSB) or same-sex marriages (SSM). Of 183 provinces or dioceses contacted, 62 (31%) replied to an online survey of which 74% had decided to allow SSB and 55% to allow SSM. While all provinces reported some losses of clergy or congregations, these were not as great as some had expected. Smaller provinces that had made spaces and time for those of differing opinions to meet together tended to report more positive outcomes than those where processes were dominated by synodical debates.
Quantitative analysis using two scales of internal (church-facing) and external (society-facing) impact showed that dioceses that allowed SSM rather than just SSB reported more positive external impact. Those that had allowed SSM reported better internal and external impact compared with those who allowed only SSB or neither. Open answers offered critical reflections highlighting important lessons learnt in the process of making decisions.
