You are just saying you overlook arbitrary decisions when it is pointing to a clear contradiction to what protestants proclaim as dogma.
If you read "The history of heresies and their refutations", by Saint Alphonse-Marie De Liguori, you will see how the steps taken to protestantism were against the very basic fundaments of a good theological Investigation.
But you would probably rather never want to look at the truth. Truth is a person. The verb (expression of God's will) of God.
