Augustine of Hippo : For "there is one God, and one Mediator between God and men, the man Christ Jesus," since "there is no other name under heaven given to men, whereby we must be saved," and "in him God has defined to all men their faith, in that he has raised him from the dead." Now without this faith, that is to say, without a belief in the one Mediator between God and humankind, the man Christ Jesus; without faith, I say, in his resurrection by which God has given assurance to all people and which no one could of course truly believe were it not for his incarnation and death; without faith, therefore, in the incarnation and death and resurrection of Christ, the Christian truth unhesitatingly declares that the ancient saints could not possibly have been cleansed from sin so as to have become holy and justified by the grace of God. And this is true both of the saints who are mentioned in holy Scripture and of those also who are not indeed mentioned therein but must yet be supposed to have existed—either before the deluge or in the interval between that event and the giving of the law or in the period of the law itself—not merely among the children of Israel, as the prophets, but even outside that nation, as for instance Job. For cleansing from sin was by the self-same faith. The one Mediator cleansed the hearts of these too, and there also was "shed abroad in them the love of God by the Holy Spirit," "who blows where he wills," not following people's merits but even producing these very merits himself. For the grace of God will in no wise exist unless it be wholly free. — ON ORIGINAL SIN 2.24.28 Bede : And there is no salvation in any other. If salvation is in no other, but only in Christ, then the fathers of the Old Testament were saved by the same Redeemer's incarnation and passion, in which we believe and hope to be saved. And though the sacraments may differ according to the times, yet the same faith agrees. For the dispensation of Christ, which we know to have been accomplished through the apostles, they learned through the prophets would come. For there is no redemption of human captivity except in the blood of Him who gave Himself as a ransom for all. — Commentary on Acts John Chrysostom : "Neither is there salvation in any other," Peter says. What wounds, think you, must these words inflict on them! "For there is none other name," he continues, "under heaven given among men, whereby we must be saved." Here he utters also lofty words. For when the object is, not to carry some point successfully, but only to show boldness he does not spare; for he was not afraid of striking too deep. Nor does he say simply, "By another;" but, "Neither is there salvation in any other": that is, He is able to save us. In this way he subdued their threatening. — Homily on Acts 10 John Chrysostom : And when there was need to teach, observe how they speak and allege many prophecies; but when the point was to use boldness of speech, then they only speak peremptorily. Thus "Neither," says he, "is there any other name under heaven given among men whereby we must be saved." It is manifest to all, he says, because not to us alone was that Name given; he cites even themselves as witnesses. "For there exists not another name under heaven, whereby we must be saved." This is the language of a soul which has renounced this present life. His exceeding out-spokenness proves here, that when he speaks in lowly terms of Christ, he does it not of fear, but of wise forbearance: but now that it was the fitting time, he speaks not in lowly terms: by this very thing intending to strike dismay into them. — Homily on Acts 10 Oecumenius : Observe also that the psalmist saying, "there is salvation in no one else," is purely clear: "This came from the Lord" is as it were the logic and the salvific bond, by which every person is not saved by any other than by the one cornerstone. — Commentary on Acts Oecumenius : For "There is no other name," that is, no venerable glory, unless this one faith centered on Christ the cornerstone alone favors and accepts the other faiths, as if the saving grace were given only in it. — Commentary on Acts Oecumenius : Consider also that where it is fitting to teach, they even bring forward prophecies, as in the earlier sermon: but when they speak freely alone, they express an opinion: "For there is no other name given," he says. And what this is has already been said. — Commentary on Acts Shepherd of Hermas : Well did you escape from it, because you cast your care on God, and opened your heart to the Lord, believing that you can be saved by no other than by His great and glorious name. On this account the Lord has sent His angel, who has rule over the beasts, and whose name is Thegri, and has shut up its mouth, so that it cannot tear you. — Shepherd of Hermas, Vision 4
