You said there that "The early church fathers rightfully understood that there is only one source of truth-the scriptures."
Of course, that is not true.
How would Abraham have received the truth when there wasn't one line of scripture written yet in his time?
Also, how would the scriptures themselves have been written if the "scriptures were the only source of truth" as you said. Where would the writers of the various documents of scripture have received the truth, if "the truth was only to be found in the scriptures", and if "the scriptures" as we know them today did not exist yet when they began writing their own "book(s)" of the Bible?
There had to be another "source of truth" besides the scriptures (and there was, and still is, and that "source of truth" is God).
The early Church fathers did not believe that statement you made in post #45, and neither should you.
OK, I'll accept that. There are two sources of truth..the word of God and the Holy Spirit. One is written. One teaches us about God. Would you agree?
1Co 2:13 And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who are spiritual.
