The principle of non-contradiction is a sophistry, like the natural order. It is created from whole cloth by theologians desparate to win an unwinnable argument. The Gospel has only been in the vernacular in this age for a few hundred years. The reason for that is that clear reading of scripture overcomes the idiocy of some doctrine. Nothing psychotic about that. Marriage is a social construct, what makes it sacramental has nothing to do with genders and+ until the Irish Sin Books were popularized, our modern concepts of confession and mortal and veniel sin did not exist.Like I said before, read a scholarly Church history, not one that is an apologetic for your cramped views.
