That's crap and you know it. The early church fathers were taught directly by the Apostles. The objective evidence is the writings of the early church Fathers which delinate how to interpret scripture as taught to them by the Apostles. That the RCC abandoned the strict constructionism of the 'rule of Faith' is not under question, is it? It is not much different than Liberals who wish a 'living document' interpretation of the Constitution. The Apostles passed along these set of beliefs so that there would be unity in the Church against the heresy of Gnosticism. This gave us the objective a priori foundation against the 'special knowledge' of the Gnostics. But now the RCC would like us to believe that the Pope has some 'special knowledge'. Ironic, isn't it?
How do you synthesize the following passages from Scripture?
Isaiah 22:22I will place on his shoulder the key to the house of David; what he opens no one can shut, and what he shuts no one can open.
Matthew 16:19
I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven."
Revelation 3:7
"These are the words of him who is holy and true, who holds the key of David. What he opens no one can shut, and what he shuts no one can open.
