Matthew 12:21

But when the same prophet represents to us even nations sometimes estimated as "the small dust of the balance," and as "less than nothing, and vanity," and sometimes as about to hope and "trust in the name" and arm of the Lord, are we at all misled respecting the Gentile nations by the diversity of statement? Are some of them to turn believers, and are others accounted dust, from any difference of nature? Nay, rather Christ has shone as the true light on the nations within the ocean's limits, and from the heaven which is over us all.

But not to this will His dispensation be confined, to the punishment of unbelievers only, but He will also win to Himself the whole world. Wherefore He added, "And in His name shall the Gentiles trust." Then, to inform thee that this too is according to the purpose of the Father, in the beginning the prophet had assured us of this likewise, together with what had gone before; saying, "My well-beloved, in whom my soul is well pleased." For of the well-beloved it is quite evident that He did these things also according to the mind of the beloved.

(De Civ. Dei, xx. 30.) This last we now see fulfilled; and thus this which cannot be denied establishes the truth of that which some have denied through ignorance, the last judgment namely, which He will hold upon earth, when he Himself shall come from heaven. For who could have expected that the Gentiles would have hope in Christ's name, when He was in the hands of His enemies, when He was bound, scourged, set at nought, and crucified; when even His disciples had lost that hope which they had begun to have in Him? That which one thief hardly hoped on the cross, the nations scattered far and wide now hope. And that they may not die for ever, they are marked with that very cross on which he died. Let none then doubt that the last judgment will be by Christ Himself.
