Faith and virtue make Christians saved, pure, holy, pleasing to God, and thereby fit to be seated with Christ. Since they are created in the Christian by grace, it is evident that through this being seated together, only the riches of God's grace will be manifested.
By grace you have been saved, you Ephesians. All who are saved are saved by grace. But the Apostle turns to the Ephesians because he now had it in mind to impress this truth more strongly upon them.
His general discussion proceeds with we. But whenever he must especially fix the Ephesians' attention on something, there he speaks as though exclusively to them.
He had already said these same words above (Eph 2:5). There they seem to have burst unexpectedly from his heart, like an exclamation, perhaps to awaken feelings of thanksgiving. Here the speech is calm, perhaps with a view to moral instruction and the lesson that no one should boast.
By salvation one may understand both the divine economy of salvation and the personal salvation of each person. The divine economy of salvation is God's pre-eternal counsel concerning it and its fulfillment. It is that the Son of God came to earth, was incarnate, suffered, died on the cross, rose, ascended into heaven, sat at the right hand of God the Father, sent down the Holy Spirit, and established the Church on earth.
The Church is the receptacle of all saving means, centered in the word of God and the mysteries. All this is the independent work of God's grace. Man, on his part, supplied neither means nor motives for it.
The personal salvation of each person begins from the preaching of the Gospel. The preachers were sent by God and guided by God where to go and what to say. All this too is the work of grace.
When the preaching is given, whether to listen or not listen, and while listening, whether to attend or not attend, and while attending, whether to consent and wish to believe or not consent and not wish, belongs to freedom.
But further, as soon as consent has been uttered in the heart and the desire for salvation by faith has formed, faith itself is sealed and transformed into living, unshakable conviction, again through the action of God's grace upon the heart.
After this, grace dwells in the heart through the mysteries and becomes the unfailing and guiding principle of life according to faith. Thus the whole ordering of salvation is accomplished by God's grace. The personal salvation of each person is also wholly from grace.
From man there is only consent to faith and the desire to be saved in this way. This accords with the character of a free creature. All the rest is accomplished by grace. Consent and desire, by themselves, will lead to nothing unless all-active grace comes.
Blessed Theodoret writes: "The grace of God counted us worthy of these blessings, and we contributed faith alone. Yet even in this divine grace works together. We did not believe of ourselves, but, being called, we came. From those who came, the Lord did not require purity of life as a condition of receiving them. Receiving faith alone, He granted remission of sins."
Saint Chrysostom, speaking more directly toward moral correction, expresses the same truth: "So that the greatness of the benefits may not puff you up, see how he humbles you by saying: by grace you have been saved. But so as not to destroy your own participation, he adds what is required from us: through faith.
"Then again he almost destroys this free participation of ours when he says: and this is not of you. Faith too, he teaches, is not from you. If Jesus Christ had not come, if He had not called us, how could we have believed? 'How shall they believe,' it is said, 'unless they hear?' (Rom 10:14).
"Thus faith, according to the Apostle's teaching, is not our possession, but God's gift. Faith is insufficient for salvation. Yet so as not to save us without any participation on our part, God requires it from us. He said that faith saves, but not by itself. It saves through God. God wills, and faith saves."
Oecumenius and Theophylact express Saint Chrysostom's last thought more clearly. They say that faith in itself has no special power, but has it because it pleased God to unite this power with it. It is pleasing to God that we be saved by faith, and therefore faith saves.
It is God's gift that we are saved through faith. Oecumenius writes: "This is God's gift because faith by itself would not have been strong enough to save, if God had not willed to save through faith. Thus both that we believe is God's gift, and that we are saved through faith is also God's gift."
Blessed Theophylact, after saying that faith is God's gift because, if the Lord had not come and called, we would not have believed, then adds: "Or otherwise: he does not call faith God's gift, but salvation through faith. This is God's gift. For let faith be ours, yet how could it alone save if God had not graciously willed to receive us on account of it, so that we should not be wholly without participation in the work of our salvation, but should appear to contribute something from ourselves?"
