They say nothing insulting against them, but are concerned with one thing only: to correct what had happened. They did not say, 'you deceivers, destroyers,' but 'troublers.' It is impossible to speak more precisely. No one could have said it so well. They say, 'souls already shaken,' as though shifting in a building what others had already laid." The very form of the epistle, its brevity and simplicity, speaks with sufficient force for its originality and authenticity. Its belonging to Saint Luke is shown by the fact that the epistle bears the undeniable mark of Saint Luke's highly characteristic style. This may be seen from parallel comparisons, for example Acts 15:23 and 23:26, and 15:29 and 21:26. But the correspondence between Lk 1:1-2 and Acts 15:24-26 is especially striking. This formal closeness of the apostolic epistle to the language of the sacred historian permits the conclusion that, when writing the history of the Apostolic Council, he did not have before him a copy of the apostolic decree. Rather, he reproduced it from memory. The sacred historian paraphrased the epistle, undoubtedly preserving fully its principal thoughts. Its artlessness and brevity speak in favor of this.
