Which tradition is true? Is it the traditions found in Roman Catholicism, Eastern Orthodoxy, etc?
“What then? After all these efforts were they tired? Did they leave off? Not at all. They are charging me with innovation, and base their charge on my confession of three hypostases, and blame me for asserting one Goodness, one Power, one Godhead. In this they are not wide of the truth, for I do so assert. Their complaint is that their custom does not accept this, and that Scripture does not agree. What is my reply? I do not consider it fair that the custom which obtains among them should be regarded as a law and rule of orthodoxy. If custom is to be taken in proof of what is right, then it is certainly competent for me to put forward on my side the custom which obtains here. If they reject this, we are clearly not bound to follow them. Therefore let God-inspired Scripture decide between us; and on whichever side be found doctrines in harmony with the word of God, in favour of that side will be cast the vote of truth.” http://www.newadvent.org/fathers/3202189.htm
