That doesn't matter. And besides they did have Scripture.
Acts 17:11 Now these Jews were more noble than those in Thessalonica; they received the word with all eagerness, examining the Scriptures daily to see if these things were so.
2 Peter 3:15-16 And count the patience of our Lord as salvation, just as our beloved brother Paul also wrote to you according to the wisdom given him, as he does in all his letters when he speaks in them of these matters. There are some things in them that are hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other Scriptures.
Colossians 4:15-16 Give my greetings to the brothers at Laodicea, and to Nympha and the church in her house. And when this letter has been read among you, have it also read in the church of the Laodiceans; and see that you also read the letter from Laodicea.
The letter to the Colossians was already in existence during NT times which clearly disproves the claim that Catholics make that the NT was transcribed from oral tradition some 400 years after the death of Christ. Else Paul could not have given the instructions He did.
And he signed it himself.
Colossians 4:10 I, Paul, write this greeting with my own hand. Remember my chains. Grace be with you.
‘Catholics make that the NT was transcribed from oral tradition some 400 years after the death of Christ.’
I find this hard to believe. So according to this theory the early Christians destroyed the letters from Paul, Peter, John, etc, and then tried to remember what was in the letters they destroyed? It never occurred to them to make copies of these precious apostolic epistles?
My willing suspension of disbelief just got stretched past the breaking point.
