But they had heard only: He, who persecuted us in times past, doth now preach the faith which once he impugned:

“"And I was still unknown by face unto the Churches of Judaea; but they only heard say, he that once persecuted us now preacheth the faith of which he once made havoc." What modesty in thus again mentioning the facts of his persecuting and laying waste the Church, and in thus making infamous his former life, while he passes over the illustrious deeds he was about to achieve! He might have told, had he wished it, all his successes, but he mentions none of these and stepping with one word over a vast expanse, he says merely, "I came into the regions of Syria and Cilicia;" and, "they had heard, that he, which once persecuted us, now preacheth the faith of which he once made havoc." The purpose of the words, "I was unknown to the Churches of Judaea," is to show, that so far from preaching to them the necessity of circumcision, he was not known to them even by sight.”

“After the Apostle has above shown that he did not receive the Gospel from man before his conversion, nor at the time of his conversion, here he proves that he did not receive it from man even after his conversion; rather, here he shows how his teaching was approved by men. And concerning this he does two things. First, he shows how his teaching was approved by the apostles; second, he shows how it was approved by the other faithful, at the place then I came into the regions, etc. And first he narrates the fact; second he confirms the truth of what he has said, at the place behold, before God, etc. He says therefore: although I did not go to the apostles in order to be instructed by them concerning the beginning of my conversion, since I was already instructed by Christ, nevertheless, driven by an affection of charity, after three years — namely, of my conversion — I came to Jerusalem, since I had for a long time desired to see Peter, not in order to learn from him, but in order to visit him. Job 5:24: "visiting your beauty," etc. And I remained with him fifteen days, being found by him to be a truthful apostle. And he says fifteen days, because this number is composed of eight and seven. Now the number eight is the number of the New Testament, in which the eighth day of those who rise again is awaited; while the number seven is the number of the Old Testament, because it celebrates the seventh day. He remained with Peter fifteen days, conferring with him about the mysteries of the Old and New Testament. And lest it be believed that, although he was not instructed by Peter, he was nevertheless instructed by others, he adds that he was not instructed by others either. Hence he says but of the other apostles I saw none, that is, no one, by whom I might have been instructed, except James the brother of the Lord. For he saw him in Jerusalem. Concerning this James it should be known that he was bishop of Jerusalem, and was called James the Less, because he had been called after the other James. Many things are said about him at Acts 15:13ff. He also wrote a canonical epistle. But why he is called the brother of the Lord is said differently by different people. For Helvidius says that he is called brother of the Lord for this reason, that he was the son of the Blessed Virgin. For he says that the Blessed Virgin conceived and bore Christ, and after the birth of Christ conceived by Joseph, and bore other sons. But this error has been condemned and rejected. Likewise it is plainly false, because James was not the son of Joseph, but of Alphaeus. Others, however, say that Joseph, before the Blessed Virgin, had another wife, from whom he had a son James and others, and when she died, he took the Blessed Virgin as wife, from whom Christ was born, yet not known by Joseph, but by the Holy Spirit, as is said in the Gospel. Because, then, kinships are named from the father, and Joseph was thought to be the father of Christ, therefore this James, although he was not the son of the Virgin, was nevertheless called brother of the Lord. But this is false, because if the Lord did not wish his mother, a virgin, to be entrusted to the keeping of anyone but a virgin, how would he have permitted her spouse not to have been a virgin, and to have remained so? Therefore others say, and it is touched on in the Gloss, that this James was the son of Mary of Cleophas, who was the sister of the Virgin. For they say that Anna, the mother of the Blessed Virgin, married first Joachim, from whom she bore Mary, the mother of the Lord; when he died, she married Cleophas, the brother of Joachim, from whom she bore Mary of Cleophas, and from her was born James the Less, Jude, and Simon; when he died, it is said that she then married a certain third man, who was called Salome, from whom she conceived and bore another Mary, who was called Salome, and from her was born James the Greater, and John, his brother. But Jerome contradicts this opinion in two ways. First, because Salome is not the name of a man, as also appears in the Greek, but is the name of a woman, who was the sister of the Blessed Virgin, and by Zebedee bore James the Greater and John, just as Mary of Cleophas by Alphaeus bore James the Less, Jude, and Simon. Now this James is called brother of the Lord specially among his other cousins, and this for two reasons: first, on account of a likeness of appearance, because he was like Christ in face; and on account of a likeness of life, because he imitated Christ in his ways. Or because Alphaeus his father was of the kinship of Joseph; and therefore, since the Jews were accustomed to trace the line of kinship from the males, and Christ was thought to be the son of Joseph, as is said in Luke 3:23, therefore he in particular was called brother of the Lord, and not the others, who were joined to him only through the mother. Here, however, "brother" is taken in the sense of kinship. For in Scripture "brothers" are sometimes said by nature. Matthew 1:2: "and Jacob begot Judah and his brothers." By kinship, as all blood relations are brothers. Genesis 13:8: "let there be no quarrel, I beg, between me and you, for we are brothers." By people, and thus all of one language are called brothers. Deuteronomy 17:15: "you may not set a man of another people as king, who is not your brother." By affection, and thus all friends, and those who have the same affection, are called brothers. 2 Corinthians 2:13: "because I did not find Titus my brother," etc. By religion, and thus all Christians who have one rule of life are called brothers. Matthew 23:8: "you are brothers," etc. Psalm 132:1: "behold how good and how pleasant it is for brothers to dwell together," etc. And commonly all men are called brothers, because they are governed and brought up by the one God. Malachi 2:10: "have we not all one father," etc. Next, when he says but the things that I write to you, etc., he confirms by an oath what he had said, as if to say: these things which I now write to you about myself, behold, they are in the open, so that it is sufficiently established that I do not lie. And this I say, before God, that is, with God as witness. Now the Apostle swears here not out of levity, but out of the necessity of those for whom it was necessary that they believe. For unless he did this, they would not believe him. 2 Corinthians 2:17: "before God, in Christ, we speak." Romans 1:9: "God is my witness," etc. What, then, does the Lord say: "let your speech be, yes, yes; no, no; what is more than this is from evil"? It must be said that it is from the evil of him who does not believe, or from the evil of the punishment by which someone is compelled to swear. Next, when he says then I came, etc., he shows how he was approved by the other churches of Judea. Here he does three things. First he shows where he stayed, namely, in Cilicia. Hence he says then I came into the regions of Syria and Cilicia, namely, of his homeland; whence also he had been carried off — for it is said at Acts 22:3: "now Paul was from Tarsus of Cilicia," etc. Second, how he was known by them, namely, not by face, but only by hearing and report. Hence he says for I was unknown by face to the churches of Judea that were in Christ, that is, in the faith of Christ. 2 Corinthians 6:8: "as unknown, and known." Whence it is clear that the churches of Judea did not teach me. For they had only heard, namely, of me by report, that he who persecuted, etc. Third, how he was approved by them, because they glorified God in me, that is, in my conversion they approved as great him who by his grace converted me. Isaiah 43:20: "the beast shall glorify me," etc.”

“But they had heard only,.... What they knew of the apostle was only by hearsay; they had never seen him, nor heard him preach, nor conversed with him, only had it reported to them; that he which persecuted us in times past; some few years ago, and not them personally, but such as were of the same faith with them, the church at Jerusalem and the members of it; which he made havoc of, committing men and women to prison, and causing others to flee to strange cities; now preacheth the faith which once he destroyed; all as in him lay he endeavoured to destroy it, though he could not entirely root it up; he destroyed many of the disciples that held it, and did all he could to discourage others from embracing and professing it; he made use of the strongest arguments he was master of to confute it, and of the secular arm to crush and extirpate it, but now was become a preacher of it: by "faith" is meant not so much the grace of faith, though to show the nature, necessity, and usefulness of faith in Christ, and to direct and encourage sensible sinners, as he did the jailer, to believe in him, was a principal part of his ministry; but rather the doctrine of faith, which is always designed, when it is said, as here, to be preached or to be obeyed, stood fast in and contended for, or to be departed and erred from, to be made shipwreck of and denied. The Gospel is called the word of faith, the mystery of faith, the faith of the Gospel, common faith, most holy faith, the faith once delivered to the saints; it contains things to be believed; it proposes and directs to the great object of faith; and is the means of implanting and increasing that grace, and without which the ministry of it is of no use: it takes in all articles of faith, respecting the divine Being, the unity of God, the trinity of persons in the Godhead, the equal and proper deity of each person, their personal distinctions from each other, the attribution of all divine works, worship and honour to them; it relates to everything concerning man, in his original creation, in his state of innocence and integrity; concerning the fall of Adam, the imputation of his sin to all his posterity, the corruption of human nature, and the impotence of man to all that is spiritually good: it regards all the acts of grace of the Father, Son, and Spirit, in and towards any of the sons of men: it includes all the doctrines of it, as of the free, sovereign, everlasting, and unchangeable love of God; of eternal, personal, and irrespective election of some to grace and glory, by which both are secured; of the everlasting, absolute, unconditional, and sure covenant of grace; of particular redemption by Christ, proceeding on a full satisfaction to divine justice; of justification by the imputed righteousness of Christ; of reconciliation and pardon by his blood; of regeneration and sanctification by the Spirit; of the perseverance of the saints in faith and holiness, the resurrection of the dead, and eternal glory: now this faith, in the several momentous branches of it, the apostle preached, published, declared, spoke out openly and publicly; fully and completely, without dropping, concealing, or keeping back anything; clearly and plainly, without using ambiguous phrases, or words of double meaning, with all faithfulness and integrity, boldness and constancy.”
