EWTN Catholic Q&A
Quid est veritas?
Question from Alma on 02-26-2018:

How do we know that what the Catholic church teaches is the truth? How do we know that the Church Fathers hadnít already been corrputed or that they were misrepresenting the truth? Why do we consider certain people to be Church Fathers and not those Christians who held different beliefs at the same time in history?
