Romans 10:16

But they have not all obeyed the gospel i.e. the gospel, or good tidings, just specified; that of "peace." Here St Paul meets from prophecy the supposed objection that the message had only partially succeeded. Innumerable Gentiles had rejected it: was not this an indication that the messengers had no commission?No: Isaiah himself had prophetically deplored just such seeming scantiness of acceptance for Messiah's message.

have not obeyed Better, did not obey. The apostolic evangelization of the Gentiles is viewed as ideally past.

Esaias saith Isaiah 53:1; quoted also, with special reference to Jewishunbelief, John 12:38.
