Vatican concerns about how some recent decisions of the U.S. Episcopal Church will impact the search for full Anglican-Roman Catholic unity are echoed in a reflection by Anglican Archbishop Rowan Williams of Canterbury, the head of the Anglican Communion. Writing about the Episcopal Church's recent general convention in which it voted to permit the priestly ordination of non-celibate homosexuals, Archbishop Williams repeatedly referred to the need to keep in mind the ecumenical implications of local church decisions in addition to their impact on the unity of the Anglican Communion as a whole. Archbishop Williams' reflection, titled "Communion, Covenant and Our Anglican Future," was published on July 27. In a statement on July 29, the Pontifical Council for Promoting Christian Unity noted Archbishop Williams' concern for maintaining the unity of the Anglican Communion through common faith and practice based on Scripture and tradition. The Vatican office "supports the archbishop in his desire to strengthen these bonds of communion, and to articulate more fully the relationship between the local and the universal within the church," the statement said. "It is our prayer that the Anglican Communion, even in this difficult situation, may find a way to maintain its unity and its witness to Christ as a worldwide communion," it added.
