Patristic Wisdom: Looking to the First Sunday in Advent

The word that came to Isaiah son of Amoz about Judea and about Jerusalem: That the mountain of the Lord will be evident in the last days, and the house of God at the top of the mountains; and it will be raised above the hills, and all the nations will come to it. And many nations will go and will say, “Come on and let us go up to the mountain of the Lord and into the house of the God of Jacob; and He will proclaim His way to us, and we will walk in it.” For a law will come out from Zion and a word of the Lord from Jerusalem. And He will judge between the nations and will refute a great people, and they will break up their swords into plows and their spears into sickles. And a nation will not take a sword against a nation, and they will no longer study to make war. And now, house of Jacob, come on, let us go to the light of the Lord. (Isaiah 2:1–5 LXX)

One can take the time to learn in what manner the prophecies of the call of the Gentiles should be understood and that they were fulfilled only after the coming of our Savior. The beginning of the prophecy is consistent with the reality that the Lord descended not only for the salvation of the Jewish race but also for that of all people, in announcing to all peoples and all the inhabitants of the earth, “Hear, all peoples, and let the earth and all in it listen.”

Eusebius of Caesarea, Proof of the Gospel 6.13

The gospel will be this “way,” of the new law and the new word in Christ, no longer in Moses. “And He shall judge among the nations,” even concerning their error. “And these shall rebuke a large nation,” that of the Jews themselves and their proselytes. “And they shall beat their swords into plowshares, and their spears into pruning-hooks;” in other words, they shall change into pursuits of moderation and peace the dispositions of injurious minds, and hostile tongues, and all kinds of evil, and blasphemy. “Nation shall not lift up sword against nation,” shall not stir up discord. “Neither shall they learn war any more,” that is, the provocation of hostilities; so that you here learn that Christ is promised not as powerful in war, but pursuing peace. Now you must deny either that these things were predicted, although they are plainly seen, or that they have been accomplished, although you read of them; else, if you cannot deny either one fact or the other, they must have been accomplished in Him of whom they were predicted.

Tertullian, Against Marcion 3.21
