Paul is apostate only to those who misunderstand or deliberately twist his teachings. By his own admission he was clearly pro-law (Rom. 3:31, 6:13, 7:12). He stated that he believed all things written in the Old Testament (Acts 24:14). In fact, Peter confirms Paul’s apostleship in 2Peter 3:15-16, “And account that the longsuffering of our Master is salvation—as also our beloved brother Paul, according to the wisdom given to him, has written to you, as also in all his epistles, speaking in them of these things, in which are some things hard to understand, which untaught and unstable people twist to their own destruction, as they do also the rest of the Scriptures.” With the exception of 134 instances where Yahweh’s Name was replaced by Adonai, the Old Testament text has remained practically untouched since its inception. This can be proved by comparing the accuracy of the many texts available to scholarship today. The Scribes and Pharisees were less guilty of modifying the text and more guilty of adding their own rabbinical, man-made traditions (Matt. 15:3).
