Flying home from his February Africa pilgrimage, Pope Francis held an unprecedented three-man press conference alongside Archbishop of Canterbury Justin Welby, leader of the Church of England and some 85 million members in the global Anglican Communion, and the Right Rev. Iain Greenshields, this year’s titular head of the Church of Scotland (equivalent of the mainline U.S. Presbyterians).

These men personify three emerging approaches to same-sex revisionism that reporters will be observing. A fourth option,of course, is strict limitation of sex to heterosexual marriage, a doctrine articulated in the Catholic Catechism and shared by all churches until recently. For example, see this summary issued last week by the Rev. J.D. Greear, a former Southern Baptist Convention president.

In the West, many “mainline” Protestant groups have shifted to option one — full-on approval of same-sex relationships, exemplified by liturgies to celebrate church weddings. The Church of Scotland joined them last May as assembly delegates gave this change 67% support. (Dissenting clergy will not be forced to perform weddings they oppose in conscience.) This followed an earlier go-ahead in America’s largest Presbyterian denomination.

With option two, Pope Francis has not proposed any alteration in the Catholic teaching that same-sex acts are sinful, but is ambiguous about how Catholic churches should welcome and potentially bless gay people (see this earlier GetReligion post on a test case in Chicago). That and his other “dialogue” initiatives rile doctrinal traditionalists. Backed by Welby and Greenshields, Francis asserted that secular law should not criminalize people for gay acts – a striking plea in Africa, where many nations outlaw gay activity and some impose the death penalty.

Then Archbishop Welby’s church made an historic decision for option three — half-way liberalization. This approach would continue to bar same-sex weddings, while approving church “blessing” ceremonies for such couples after their civil marriages (legal in England since 2013). After six years of formal nationwide church discussion, and more than eight hours of floor debate, the General Synod voted February 9 to “welcome” that policy, which the bishops approved in January.

The motion expressed repentance over past and present “harm that LGBTQI+ people have experienced” in church. Welby and the Archbishop of York jointly stated that their church “will publicly, unreservedly and joyfully welcome same-sex couples.” This includes sexually active same-sex couples? Debate continues on that point.

This decision by no means settles matters.
