Hebrews 3:9, 1 John 2:13 (well, the latter is obviously not St. Paul, which is in itself a corroboration).
1 John 2:13
I am writing to you, fathers,
because you know him who is from the beginning.
I am writing to you, young men,
because you have overcome the evil one.
Well; you DID find some verses with the word FATHER in them.
