Of course If you are studying "History according to the Catholic church", and I study Christian history in general, then our finds will differ, unless we could find a way to go back in time and monitor the writings themselves, we won't know who's right until we see Christ himself.
I was a history major in college with a minor in Classics. I read Latin and (mostly Classical) Greek. I've read the New Testament AND the Church Fathers in the original in the course of my studies. Have you?
That was years before I became a Catholic, BTW. I was an Episcopalian at the time.
If you insist on first hand monitoring of all writings, then you deny the reality of history. There's more direct evidence for Christ and the Church Fathers than there is for Alexander the Great or Julius Caesar.
But, you are right on one point. Then we will see face to face, and know as we are known. Until then, we should diligently apply ourselves to prayer and study.
