In order to persuade him, we reminded him of the great example left us by the apostles and of the traditions of the fathers. Even though the grace of the holy Spirit was abundant in each of the apostles, so that none of them required the advice of another in order to do his work, nevertheless they were loathe to come to a decision on the issue of the circumcision of gentiles until they had met together to test their various opinions against the witness of the holy scriptures.
In this way they unanimously reached the conclusion which they wrote to the gentiles: It has seemed good to the holy Spirit and to us to lay upon you no greater burden than these necessary things; that you abstain from what has been sacrificed to idols and from blood and from what is strangled and from unchastity.
The holy fathers, who have gathered at intervals in the four holy councils, have followed the examples of antiquity. They dealt with heresies and current problems by debate in common, since it was established as certain that when the disputed question is set out by each side in communal discussions, the light of truth drives out the shadows of lying.
The truth cannot be made clear in any other way when there are debates about questions of faith, since everyone requires the assistance of his neighbour. As Solomon says in his proverbs: A brother who helps a brother shall be exalted like a strong city; he shall be as strong as a well-established kingdom. Again in Ecclesiastes he says: Two are better than one, for they have a good reward for their toil. And the Lord himself says: Amen I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven. For where two or three are gathered in my name, there am I in the midst of them.
The 'example of antiquity' here is the interaction of the apostles in Acts 21, what has occasionally been called the 'Council of Jerusalem'.
I find this a fascinating passage, and worthy of meditation. I will be saying something more about it soon, you can be sure.
