Comment: Chalecedon, Ephesus and Nicea were change and they can't now because of our agreement of them, not because we know any new knowledge about the Trinity. Sexual doctine is ripe for change. This generation will not let the Church exist in its current form for long. Continence was not Chrisitian but Stoic. It can not only be reversed, it must be. Calling Masturbation a mortal sin was also fairly recent, as is the current pastoral trend to not do so. We were given the Paraclete because we are to change. Read John 16 if you have any doubt about that.

12 I still have many things to say to you, but you are not able to bear them[c] now. 13 But when he—the Spirit of truth—comes, he will guide you into all the truth. For he will not speak from himself, but whatever he hears he will speak, and he will proclaim to you the things to come.
