Are the Early Church Fathers Infallible?

When, if ever, is it reasonable or to disagree with the early church fathers regarding what scripture teaches? When? A, whenever it seems right to do soa. And i'd also saywt, also depends on your tradition and what oure gong to take as de fide. So ther there're going to be constraints what a particular christiana tradition one belongs to. But i agree is manytimes san be case by case.
