Earlier you said the bible contains errors... do not the fathers also contain errors? They do not even agree with each other on many items...
“...do not the fathers also contain errors?”
They certainly do, R! Orthodoxy makes no claim that any individual is infallible. It’s one of the main differences between Orthodoxy and Roman Catholicism.
And the Fathers disagree among themselves on various matters. But there is a consensus of teachings among the Fathers on many subjects and that consensus is among the foundation stones of the Faith.
