If the Catholic Church is what it claims to be then nothing will change because the truth of Catholicism is predicated on the fact that settled teaching (in this case natural law sexual ethics and holy orders being open to men alone) cannot change.
Of course it can change. The Christian God began as one of many tribal gods (and not the first) in the Canaanite pantheon, and [he] had a consort Asherah.
Only after the Babylonian captivity does [he] become the only god. Then in the first century [he] becomes the Christian god who, unlike the Jewish god, abandons the covenant of circumcision. Then in the fourth century [he] becomes a Trinity, and in the process Jesus, who has repeatedly denied he's God, and the Ghost, who was the ruach, the breath of God, but not an entity distinct from God, becomes God too.
Then the Christian god took on a variety of national forms, Eastern and Western and Coptic and I dare say more.
Then the Western Christian God became the god of protestants and the god of Catholics.
And now there are thousands of versions of [him] and [he] doesn't appear to be in the slightest concerned about it, since [he] just goes on looking on and doing and saying nothing.
Correct me if I got any of that wrong. When I say 'wrong' I mean historically wrong, of course, not dogmatically wrong,
