And certain men which came down from Judaea taught the brethren, and said, Except ye be circumcised after the manner of Moses, ye cannot be saved. When therefore Paul and Barnabas had no small dissension and disputation with them, they determined that Paul and Barnabas, and certain other of them, should go up to Jerusalem unto the apostles and elders about this question. And being brought on their way by the church, they passed through Phenice and Samaria, declaring the conversion of the Gentiles: and they caused great joy unto all the brethren. And when they were come to Jerusalem, they were received of the church, and of the apostles and elders, and they declared all things that God had done with them. But there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses. And the apostles and elders came together for to consider of this matter. And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe. And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us; And put no difference between us and them, purifying their hearts by faith. Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear? But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they. Then all the multitude kept silence, and gave audience to Barnabas and Paul, declaring what miracles and wonders God had wrought among the Gentiles by them. And after they had held their peace, James answered, saying, Men and brethren, hearken unto me: Simeon hath declared how God at the first did visit the Gentiles, to take out of them a people for his name. And to this agree the words of the prophets; as it is written, After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up: That the residue of men might seek after the Lord, and all the Gentiles, upon whom my name is called, saith the Lord, who doeth all these things. [Amos 9:11-12] Known unto God are all his works from the beginning of the world. Wherefore my sentence is, that we trouble not them, which from among the Gentiles are turned to God: But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood.
And thus do the words of the prophet agree, as it is written, “After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build its ruins and set it up. The remnant may seek after the Lord, and all the Gentiles among whom my name has been invoked, says the Lord, doing these things.” His works are known from eternity by God. Therefore I for my part give this judgment, that we do not trouble those who from among the Gentiles are turned to God.
Listen to the prophet saying, “I will raise up the tabernacle of David that has fallen.” Actually, it has fallen; our human nature has had an irreparable fall and was in need of that powerful hand alone. For it was not possible to raise it up otherwise, unless he who fashioned it in the beginning stretched out a hand to it and formed it again from above by the regeneration of water and the Spirit. Behold, pray, the awesome and ineffable character of the mystery. He dwells always in this tabernacle, for he put on our flesh, not to put it off again but to have it always with him. If this were not so, he would not have deemed it worthy of his royal throne.
(Vers. 11 seqq.) In that day I will raise up the fallen tent of David, and rebuild its broken walls, and restore what has collapsed, and rebuild it as it was in ancient times, that they may possess the remnant of Edom and all the nations who are called by my name, declares the Lord who is doing these things. LXX: In that day I will raise up the fallen tent of David, and rebuild its broken parts, and raise up what has been buried, and restore it as in the ancient days, that they may seek me, the remnant of humanity, and all the nations over whom my name has been called, declares the Lord who is doing all these things. Where the authority of the apostles prevails, especially that of Peter and James, whom the vessel of election calls the pillars of the Church (Galatians 2), there all suspicion of various explanations is to be removed, and what is expounded by such great men is to be followed. In the book of Acts, a question arose among the apostles as to why Paul and Barnabas had received men from the Gentiles without circumcision and observance of the Sabbath. Peter answered, as he should: and James, approving his opinion, spoke these words: Men, brothers, listen to me: Simon has related how God first visited the Gentiles to take from them a people for his name, and the words of the prophets agree with this, as it is written: After this, I will return and rebuild the fallen tent of David. I will rebuild its ruins and set it up again, so that the rest of mankind may seek the Lord, even all the Gentiles who are called by my name, says the Lord, who does these things, known from of old (Acts 15:13 and following). Therefore this tabernacle of David, which had fallen (had fallen, however, among those who say, it will not come near, and no evil will come upon us: those whom the Lord had shaken and tested with His sieve, and whose threshing floor of His majesty He had purged with His winnowing fan, and all sinners He had killed with the sword), now according to the custom of the Scriptures, after tortures, after punishments, promising prosperity and joy, declares that He will raise it up, and in the resurrection of the Lord restore all things, so that what had fallen in the synagogues may rise in the Churches, and believers may possess the remnants of Edom, and all nations, so that whatever remains of the bloody and earthly kingdom may be transformed into heavenly kingdoms, and all peoples who have forgotten the Lord may be converted and return to Him. But if we want to read according to the LXX, those who are left of mankind, and all the nations upon whom my name has been invoked, we should accept as those who have believed from the Jewish people, and as those who have not fallen like a small stone from the sieve, nor have been thrown out with the dust and chaff. For the remnants will be saved at the beginning of faith, and at the end of the world, so that when the fullness of the Gentiles comes in, then all Israel will be saved (Romans 11). But the name of the Lord which is invoked above the rest and above all nations, that is what the Savior says: Father, I have revealed your name to men (John 17:6). And so that I do not delay the rule of covenants with a long discourse, and in this prophet, and in the other things whatsoever are preached about the building of Jerusalem (the walls of Jerusalem) and the temple, and the blessedness of all things, the Jews in the last time promise themselves in vain expectation, and they mention things to be fulfilled carnally. But we who do not follow the letter that kills, but the life-giving Spirit, now in the Church we are convinced of fulfillment, and every day it is fulfilled in individuals who, falling through sin, are rebuilt through repentance.
But let us hear what Hosea goes on to say: “And after this the children of Israel shall return, and shall seek the Lord their God, and David their king. And they shall fear the Lord and his goodness in the last days.” You will never find a prophecy plainer than this, for the name king David means Christ who, as St. Paul says, “was born according to the flesh of the offspring of David.” Further on still, Hosea foretold the resurrection of Christ on the third day, but in the mysterious way that is proper to prophecy. He says, “He shall heal us after two days, and on the third day we shall rise up again.” This is the idea underlying the words of St. Paul: “Therefore if you have risen with Christ, seek the things that are above.” The prophet Amos too has predictions not unlike those of Hosea. He says, “Be prepared to meet your God, O Israel, for behold, I am the one who forms the thunder, and creates the wind, and declares to men their Christ.” And, in another place: “ ‘In that day I will raise up the tabernacle of David that is fallen. And I will close up the breaches of the walls thereof and repair what is fallen. And I will rebuild it as in the days of old, so that the remnant of men may seek me out, and all nations, because my name is invoked upon them,’ says the Lord that does these things.”
all the nations who are called by my name: If then it was to this end that the city rose again (namely) because of Jesus (that was to come) of them, it shows that of the building of the city the cause is, the calling of the Gentiles.
