You aren’t answering the question. The Church, by the authority given to Peter and subsequent Popes, have defined and proposed teaching for belief. This includes the Patristics. Do the Fathers agree on everything? Nope. However, it is the Church who has the authority to determine what is and isn’t authentic.
Either you take the Bible for what it is or you don’t, as Luther and the like. The same is true for the Patristics.
In the end, you are rejecting the authority of the Church, given it by Jesus Christ himself. You have made yourself the sole arbiter.
I'm not avoiding THE ISSUE:
How do Catholics decide which TEACHING to follow?
