Amchurch?
Do you mean the Catholic Church in America?
Yes. The expression is from Paul Likoudas’ book Amchurch Comes Out (2004) about the homosexual dissent movement within the Catholic clergy in America.
My reference is to a schismatic movement, not to the whole Church in America - although certain Jesuits have threatened that, if Rome should take measures to truly suppress homosexualism in the clergy that many or even most churches in America would not have priests.
This is certainly an exaggeration, but the problem is very large and if it is successfully suppressed the resulting church will be very different, IMO.
