Acts 21:25

This repetition of the agreement of the so-called council in Jerusalem was made for the sake of assuring Paul that there had been no "backing out" of the agreement; but that it still held. Implicit in James' proposal, however, was the proposition of TWO DIFFERENT BODIES of Christians being promulgated, one keeping the law of Moses, the other not; a premise which it is certain that Paul never for one moment accepted. In fact his efforts in this chapter were dedicated to a resolution of the differences in the two groups which ALREADY EXISTED.
