There some Protestant clergy that allow women priesthood. This concept develop in the modern sexual revolution. Women priesthood was never established by Jesus Christ.
To prove my case, in the OT the Levite priesthood were all men not women. Since Jesus is a Jew, he established that his Church will be run by men. He commissioned Twelve Men as his Apostles. There were indeed women disciple but they took no part in early Church affair.
There were no women in the Council of Jerusalem, only elders, and men. The Catholic Church as well as the Orthodox Church upheld that women should not be priest because it was never established by Jesus Christ himself.
The Bishops who are the successors of the Apostles are men. So ordination of women by an Church is therefore invalid.
