Clyde Pilkington and the rest of the Acts 28 theorists claim that all of Paul's early letters (Romans; 1 &2 Corinthians; 1 & 2 Thessalonians, and Galatians) are founded upon Israel and the Old Testament. Only Paul's last seven letters are for us today, the early letters belonging to an "old body of Christ," the latter letters to a "new body." This division is random, careless, confusing, and divisive. Really, it's a sin. One really must strain to come up with a motive that
requires so much complicated parsing.
The torpedo that sinks the ship of Paul's gospel—described in Romans and Galatians, for example—being "founded upon Israel and the Old
Testament" is Paul's testimony in Galatians chapter one, verses 11 and 12: "For I am making known to you, brethren, as to the evangel which is being brought by me, that it is not in accord with man. For neither did I accept it from a man, NOR WAS I TAUGHT IT, but it came through a revelation of Jesus Christ."
