Cap. IX Arg. 3 Sol: Docete omnes gentes / Predicate omni creaturae — apostolic authority for the whole world; wall between Jew and Gentile down
From Christ's charges Teach all nations and Preach to every creature it rightly follows that those disciples were given apostolic authority — not pinned to one church or nation, but aimed at the whole world. It also follows that the wall which shut Gentiles from God's church was broken down, and that the Gospel was to be preached not to Jews alone but to Jews and Gentiles, Greeks and barbarians, wise and unwise — as Paul says in Rom. 1.
Latin
Ex illis mandatis Christi Docete omnes gentes, Predicate omni creaturae, recte colligitur, Discipulis illis auctoritatem Apostolicam, id est, non particulari alicui Ecclesiae aut nationi affixam, sed ad totum terrarum orbem spectantem, fuisse demandatam. Recte etiam infertur, Maceriam illam, quae Gentes ab Ecclesia Dei disterminavit, dirutam fuisse, et debuisse Evangelium, non uni nationi Judaeorum, sed Judaeis et Gentibus, Graecis et barbaris, sapientibus et insipientibus, praedicari, ut loquitur Paulus Rom. i.
