Acts 15:6

And the apostles and elders ... - They came together in accordance with the authority in Matthew 18:19. It would seem, also, that the whole church was convened on this occasion, and that the church concurred, at least, in the judgment expressed in this case. See Acts 15:12, Acts 15:22.

For to consider of this matter - Not to decide it arbitrarily, or even by authority, without deliberation; but to compare their views, and to express the result of the whole to the church at Antioch. It was a grave and difficult question, deeply affecting the entire constitution of the Christian church, and they therefore solemnly engaged in deliberation on the subject.
