Amos 9:11

14. This is shown in a still clearer light from the letter of the apostles, which they forwarded neither to the Jews nor to the Greeks, but to those who from the Gentiles believed in Christ, confirming their faith. For when certain men had come down from Judea to Antioch, where also, first of all, the Lord’s disciples were called Christians, because of their faith in Christ, and sought to persuade those who had believed on the Lord to be circumcised, and to perform other things after the observance of the law; and when Paul and Barnabas had gone up to Jerusalem to the apostles on account of this question, and the whole Church had convened together, Peter thus addressed them: “Men, brethren, ye know how that from the days of old God made choice among you, that the Gentiles by my mouth should hear the word of the Gospel, and believe. …

XII. Wherefore observe that these are the very things which the Lord wished to teach to the Sadducees, who did not believe in the resurrection of the flesh. For this was the opinion of the Sadducees. Whence it was that, having contrived the parable about the woman and the seven brethren, that they might cast doubt upon the resurrection of the flesh, “There came to Him,” it is said, “the Sadducees also, who say that there is no resurrection.” Christ, then, if there had been no resurrection of the flesh, but the soul only were saved, would have agreed with their opinion as a right and excellent one. But as it was, He answered and said, “In the resurrection they neither marry, nor are given in marriage, but are as the angels in heaven,” not on account of having no flesh, but of not marrying nor being married, but being henceforth incorruptible. …

XII . But because this heresy did then seem the more powerful to seduce men, and the whole Church was in danger, we the twelve assembled together at Jerusalem (for Matthias was chosen to be an apostle in the room of the betrayer, and took the lot of Judas ; as it is said, “His bishopric let another take”). We deliberated, together with James the Lord’s brother, what was to be done; and it seemed good to him and to the elders to speak to the people words of doctrine. …

The prophet Hosea speaks so very profoundly that it is laborious work to penetrate his meaning. But, according to promise, we must insert something from his book. He says, “And it shall come to pass that in the place where it was said unto them, Ye are not my people, there they shall be called the sons of the living God.” Even the apostles understood this as a prophetic testimony of the calling of the nations who did not formerly belong to God; and because this same people of the Gentiles is itself spiritually among the children of Abraham, and for that reason is rightly called Israel, therefore he goes on to say, “And the children of Judah and the children of Israel shall be gathered together in one, and shall appoint themselves one headship, and shall ascend from the earth.” We should but weaken the savor of this prophetic oracle if we set ourselves to expound it. …

What then was the tabernacle in which He dwelt? Hear the Prophet say; “I will raise up the tabernacle of David that is fallen.” ( Amos ix. 11 .) It was fallen indeed, our nature had fallen an incurable fall, and needed only that mighty Hand. There was no possibility of raising it again, had not He who fashioned it at first stretched forth to it His Hand, and stamped it anew with His Image, by the regeneration of water and the Spirit. And observe I pray you, the awful and ineffable nature of the mystery. He inhabits this tabernacle for ever, for He clothed Himself with our flesh, not as again to leave it, but always to have it with Him. Had not this been the case, He would not have deemed it worthy of the royal throne, nor would He while wearing it have been worshiped by all the host of heaven, angels, archangels, thrones, principalities, dominions, powers. …
