The consistent teaching of the church for centuries is that Holy Orders is open only to males. If the pope is going to change any of that, he should open the priesthood to married men.
If he opens it to women, half of those who apply will be lezzies.
There is no theological reason per se why married men cannot be ordained. The Catholic Church-- East and/or West --- has always called at least some of its priests from the ranks married men.
Women -- that's an entirely different thing. Following the example of Our Lord, the whole Church --- East and West--- has always taught that Holy Orders involves a representation of Christ the Bridegroom; and the one thing a woman can't do is "embody" Christ as Bridegroom.p> Therefore women CANNOT be ordained through the reception of Holy Orders.
Not "We don't wanna." Not "should not." Not "ought not." CANNOT.
