This would be the purpose of the Councils made up of Bishops from all quarters. The main questions at Nice would appear to be Christological, therefore the Bishops would answer on the principal of what they had been taught by earlier bishops and compared to what scripture was in 1325. (Tradition). Archbishop Laud, said in his,'Reply to Fisher the Jesuit' , (I think, ) that those general councils , that are freely called, freely accepted and honestly organised, after being freely studied and accepted by the particular churches, without any pressure are to be deemed infallible. This was probably, from Laud's reply to Fisher! He had three other replies though to Accusations made in the Lords, when he was on trial for his life. Unfortunately , though I have them from Google, they are on sony e-readers and I'm having trouble with repairs.
