Justified, Sanctified, i.e. Saved by Grace through Faith...

Ephesians 2:8-10:  For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship,created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.

From John Calvin's Ephesian commentary:

For by grace are ye saved... This is an inference from the former statements. Having treated of election and of effectual calling, he arrives at this general conclusion, that they had obtained salvation by faith alone. First, he asserts, that the salvation of the Ephesians was entirely the work, the gracious work of God. But then they had obtained this grace by faith. On one side, we must look at God; and, on the other, at man. God declares, that he owes us nothing; so that salvation is not a reward or recompense, but unmixed grace. The next question is, in what way do men receive that salvation which is offered to them by the hand of God? The answer is, by faith; and hence he concludes that nothing connected with it is our own. If, on the part of God, it is grace alone, and if we bring nothing but faith, which strips us of all commendation, it follows that salvation does not come from us...

What remains now for free-will, if all the good works which proceed from us are acknowledged to have been the gifts of the Spirit of God? Let godly readers weigh carefully the apostle's words. He does not say that we are assisted by God. He does not say that the will is prepared, and is then left to run by its own strength. He does not say that the power of choosing aright is bestowed upon us, and that we are afterwards left to make our own choice. Such is the idle talk in which those persons who do their utmost to undervalue the grace of God are accustomed to indulge. But the apostle affirms that we are God's work, and that everything good in us is his creation; by which he means that the whole man is formed by his hand to be good. It is not the mere power of choosing aright, or some indescribable kind of preparation, or even assistance, but the right will itself, which is his workmanship; otherwise Paul's argument would have no force. He means to prove that man does not in any way procure salvation for himself, but obtains it as a free gift from God. The proof is, that man is nothing but by divine grace. Whoever, then, makes the very smallest claim for man, apart from the grace of God, allows him, to that extent, ability to procure salvation.

Could these be Anti-nomian musings or are John Calvin's words understood to be
the Gospel proper - the power of salvation unto everyone who believes in Christ alone?
