By grace are ye saved through faith. — Properly, ye have been saved; ye were saved at first, and continue in a state of salvation. In Ephesians 2:5 this thought is introduced parenthetically, naturally and irresistibly suggested by the declaration of the various steps of regeneration in Christ. St. Paul now returns to it and works it out, before passing on, in Ephesians 2:11, to draw out by “wherefore” the conclusion from Ephesians 2:1-7. Remembering how the Epistles were written from dictation, we may be inclined to see in this passage among others, an insertion made by the Apostle, on a revision of that already written.
The two phrases — “justification by faith” and “salvation by grace” — are popularly identified, and, indeed. are substantially identical in meaning. But the latter properly lays stress on a more advanced stage of the process of redemption in Christ. Thus, in Romans 5:9-10 (“having been justified,” “having been reconciled,” “we shall be saved”), salvation is spoken of as following on the completed act of justification (as the release of a prisoner on his pronounced pardon); and it is described, here and elsewhere, as a continuous process — a state continuing till the final judgment. Hence to lay especial stress on salvation accords better with the whole idea of this Epistle — the continuous indwelling in Christ — than to bring out, as in the Epistle to the Romans, the one complete act of justification for His sake. It is remarkable that the expression of the truth corresponds almost verbally with the words of St. Peter at the Council of Jerusalem (Acts 15:11), “We believe that through the grace of God we shall be (properly, we were) saved,” except that here the original shows that the salvation is looked upon as a completed act, like justification. It is also to be noted that the use of the name “Saviour,” applied both to God and to Christ, belongs entirely to the later Epistles. It is used once in this Epistle (Ephesians 5:23) and once in the Epistle to the Philippians (Ephesians 3:20), but no less than ten times in the Pastoral Epistles of St. Paul, and five times in the Second Epistle of St. Peter. The phrase in the text is, as always in this Epistle, theologically exact. Grace is the moving cause of salvation: faith only the instrument by which it is laid hold of.
And that not of yourselves: it is the gift of God. — This attribution of all to the gift of God seems to cover the whole idea — both the gift of salvation and the gift of faith to accept it. The former part is enforced by the words “not of works,” the latter by the declaration, “we (and all that is in us) are His workmanship.” The word here rendered “gift” is peculiar to this passage; the word employed in Romans 5:15-16; Romans 6:23, for “free gift” (charisma) having been appropriated (both in the singular and plural) to special “gifts” of grace.
