I’m going to make the case that there were Scriptures among the first century Christians (not just OT Scripture). If you accept that the NT was written by the various apostles then it was nearly complete by the mid 60s AD. By that time I believe only John was still alive. Peter and James addressed their epistles to Christians in wide areas. Paul instructed the Colossians to share their letter with the Laeodicians (Laodiceans? Laeodeceans?) Peter instructs Christians to grow in grace and knowledge, pretty difficult if there is no reading material. Peter also mentions Paul’s letters, and warns that people will distort his words. Paul quotes Luke’s Gospel in Timothy. Letters were being copied and shared all over. Even NT critic Bart Ehrman conceded that Christianity was an exceptionally literate religion in an illiterate time. By the early second century ECFs had quoted from almost all the books of the NT (I believe Revelations, 2 and 3 John). It is very possible that early Christians did have some of the NT. So don’t discount the role of Scripture in the early history of the church.
I don’t believe anyone is discounting the role of Scripture in the early church. But what is being discounted is the role of Tradition in the early church. That is the crux of the sola scriptura discussion. It seems that the sola scripturists want to frame the discussion in terms of pro scripturists and anti scri[pturists and that is most certainly not the case. The proper frame of the discussion should be the pro Oral Traditionists and the anti Oral Traditionists. So the question I propose to you is thus: In light of Paul’s command in 2Thess 2:15 to hold onto both the oral and the written Tradition how can you deny the Oral Tradition? For your benefit I listed 2 Thess 2:15 in diffrerent Bible versions which state thusly:
“So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.” [RSV]
“Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.” [KJV]
“Therefore, brethren, stand fast & keepe the instructions, which ye haue bene taught, either by worde, or by our Epistle.” [Geneva Bible]
“So then, brethren, stand fast, and hold the traditions which ye were taught, whether by word, or by epistle of ours.” [NSV]
“Therefore, brethren, stand fast: and hold the traditions, which you have learned, whether by word or by our epistle.” [DR]
