Why are you excluding the ones that allow it? Why not include Episcopalians? Or Judaism? Presbyterians?
I specifically included traditional Anglicans, who still constitute a visible minority of Episcopal church members, including the graduates of one of their seminaries, and many parishes and dioceses throughout the US who hope to change the Episcopal Church from within and wish to avoid causing money to be wasted in lawsuits which they will lose, if a parish, but win, if a diocese, under the policy implemented by the former presiding bishop, which may have changed following the ECUSA’s loss in the Fort Worth case, but still, and I also included Orthodox Judaism, which is actually opposed to abortion under many circumstances. As for Presbyterianism, it didn’t occur to me to include it since it is not one of the more ancient liturgical forms of Christianity, however, if I were to include it, it would be in support of my position, since the vast majority of the world’s Reformed and Presbyterian denominations are pro-life, in the US including the PCA, OPC, eCo, and RPCNA, as well as the closely related Christian Reformed Church.
While unfortunately advocates of various contemporary theological schools such as Liberation Theology, Queer Theology and Postmodern Theology have come to dominate the mainline Protestant churches, which has been correlated with, and in several instances, where they have changed the doctrine of those churches, causally linked, with enormous declines in membership, the vast majority of Christians are pro-life, whether Roman Catholic, Baptist or Orthodox (indeed seeing members of so many denominations working together to organize pro-life demonstrations, to fund crisis pregnancy centers, and to provide financial assistance for single parents.
And considering that the only liberal denomination that is experiencing meaningful growth is the Unitarian Universalist Association, which considers itself “Post-Christian” and which has only a small number of heterodox Unitarian Christian churches left, such as King’s Chapel in Boston, it is likely that the sale of church properties by the mainline denominations to more traditional churches will continue, and also the likelihood of traditional Christians reasserting control increases. Indeed recently an Episcopal diocese sold their cathedral to an evangelical mega-church; this did not trouble me in the slightest as the cathedral was widely regarded as being the ugliest work of Brutalist church architecture in North America.
