Does 1 Cor. 15 make your last sentence false? Does this scripture stand with your or against you?<quoted text>
As I'm sure you're aware (but probably convinced yourself otherwise) that Pauls letter to Timothy was telling him that scripture is profitable for teaching...
The scripture Paul was referring to would be the Hebrew Books the Apostles considered scripture. It would not have been his letter Timothy was reading. Nor would it have been future letters or Johns Revelation - which came at a later date.
Even so, Paul did NOT say scripture is the ONLY thing. You guys said this 1600 yrs later.
In fact Paul says the exact opposite in his letter to the Thessalonians "Hold steadfast to your traditions, taught to you by word of mouth AND letter" 2Thess 2:15
Any mention of scripture in the New Testament by the Apostles is always referring to the OT.
"Now, brothers and sisters, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand. 2 By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.
3 For what I received I passed on to you as of first importance[a]: that Christ died for our sins according to the Scriptures, 4 that he was buried, that he was raised on the third day according to the Scriptures, 5 and that he appeared to Cephas,[b] and then to the Twelve. 6 After that, he appeared to more than five hundred of the brothers and sisters at the same time, most of whom are still living, though some have fallen asleep. 7 Then he appeared to James, then to all the apostles, 8 and last of all he appeared to me also, as to one abnormally born.
