I hold to the "historical doctrine of the Trinity".
Assuming that you know what the historical doctrine of the Trinity actually teaches (see the Council of Nicaea, the Council of Constantinople and the Council of Chalcedon), then you have changed after all. Catholics everywhere will rejoice at the news. (I love irony.)
You accept and hold as your own personal belief the historical doctrine of the Trinity.
I reject and do not hold as my own personal belief the historical doctrine of the Trinity.
If anyone asks, that’s what I’ll tell them. It’s the right thing to do.
If anyone testifies otherwise about you, I’ll use your testimony against them to defend you. Why? It’s the right thing to do.
However, once another doctrine, comes along, that says...>"and you must believe in that, to go to heaven"...then i leave it behind.
Good on you. You reject the anathemas contained in the Athanasian Creed.
Meanwhile, and sadly, trinitarian on trinitarian violence will continue unabated.
Shoot the non-trinitarian peacemaker and shake hands.
