A statement (see below) indicates that same sex marriage was the reason. To wit: “Recent developments in The Episcopal Church with respect to a change in their Canon on marriage represent a fundamental departure from the faith and teaching held by the majority of our Provinces on the doctrine of marriage. Possible developments in other Provinces could further exacerbate this situation.”
The primates of the Anglican Communion have suspended the Episcopal Church from full participation in the life and work of the Anglican Communion. On 14 January 2016 a motion was presented to the gathering of archbishops and moderators gathered in the crypt of Canterbury Cathedral that called for the Episcopal Church to be suspended for a period of three years. The resolution as shared with Anglican Ink calls for the Episcopal Church to lose its “vote” in meetings of pan-Anglican institutions and assemblies, but preserves its “voice”, demoting the church to observer status.. The motion asks that representatives of the Episcopal Church not be permitted to represent the Communion in interfaith and ecumenical bodies or dialogue commissions, nor serve on the Standing Committee of the Anglican Consultative Council, nor vote at meetings of the Anglican Consultative Council — whose next meeting is this summer in Lusaka. Unlike the recommendations of the Windsor Report, which called for the “voluntary withdrawal” of the Episcopal Church from the life of the Communion, today’s vote directs the archbishop to discipline the American church. The Episcopal Church may not take part in the decision making process “on issues of doctrine or polity”, either, agreed the primates. The motion further asked the Archbishop of Canterbury to “appoint a task group to maintain conversations among ourselves with the intention of restoration of relationship, rebuilding of mutual trust, healing the legacy of hurt, recognising the extent of commonality, and exploring our deep differences, ensuring they are held in the love and grace of Christ.”
The Anglican statement:
Today the Primates agreed how they would walk together in the grace and love of Christ. This agreement acknowledges the significant distance that remains but confirms their unanimous commitment to walk together. The Primates regret that it appears that this document has been leaked in advance of their communiqué tomorrow. In order to avoid speculation the document is being released in full. This agreement demonstrates the commitment of all the Primates to continue the life of the Communion with neither victor nor vanquished. Questions and further comments will be responded to at a press conference tomorrow at 1500. Full details are available here. The full text is as follows: 1. We gathered as Anglican Primates to pray and consider how we may preserve our unity in Christ given the ongoing deep differences that exist among us concerning our understanding of marriage. 2. Recent developments in The Episcopal Church with respect to a change in their Canon on marriage represent a fundamental departure from the faith and teaching held by the majority of our Provinces on the doctrine of marriage. Possible developments in other Provinces could further exacerbate this situation. 3. All of us acknowledge that these developments have caused further deep pain throughout our Communion. 4. The traditional doctrine of the church in view of the teaching of Scripture, upholds marriage as between a man and a woman in faithful, lifelong union. The majority of those gathered reaffirm this teaching. 5. In keeping with the consistent position of previous Primates’ meetings such unilateral actions on a matter of doctrine without Catholic unity is considered by many of us as a departure from the mutual accountability and interdependence implied through being in relationship with each other in the Anglican Communion. 6. Such actions further impair our communion and create a deeper mistrust between us. This results in significant distance between us and places huge strains on the functioning of the Instruments of Communion and the ways in which we express our historic and ongoing relationships. 7. It is our unanimous desire to walk together. However given the seriousness of these matters we formally acknowledge this distance by requiring that for a period of three years The Episcopal Church no longer represent us on ecumenical and interfaith bodies, should not be appointed or elected to an internal standing committee and that while participating in the internal bodies of the Anglican Communion, they will not take part in decision making on any issues pertaining to doctrine or polity. 8. We have asked the Archbishop of Canterbury to appoint a Task Group to maintain conversation among ourselves with the intention of restoration of relationship, the rebuilding of mutual trust, healing the legacy of hurt, recognising the extent of our commonality and exploring our deep differences, ensuring they are held between us in the love and grace of Christ.
