Witnesses in the apostolic era carries no weight against the Scripture. Many people during the apostles time had already drifted into error as proven by the Bible.
Tit 1:10 For there are many unruly men, vain talkers and deceivers, specially they of the circumcision,
Tit 1:11 whose mouths must be stopped; men who overthrow whole houses, teaching things which they ought not, for filthy lucre's sake.
Tit 1:12 One of themselves, a prophet of their own, said, Cretans are always liars, evil beasts, idle gluttons.
2Jn 1:7 For many deceivers are gone forth into the world, even they that confess not that Jesus Christ cometh in the flesh. This is the deceiver and the antichrist.
2Jn 1:8 Look to yourselves, that ye lose not the things which we have wrought, but that ye receive a full reward.
