If we allow women to be priests then we'll have women bishops, then eventually a woman pope. Now I have always said that I will be candid, I don't have theology but I don't like the idea of all this from a question of what is proper, though not in the moral sense. The church is not a democracy with civilians and a bill of rights. Women can be theologians, professors, even canon lawyers, is that not correct? To say that women have not progressed in the church in their roles is not accurate. 
If everything is going to be thrown open to a question of what is morally right, then is it morally right not to marry gays in the church? Is that ok?
