1540 · John Calvin, Commentary on Romans 11.6
Paul speaks not here of our reconciliation with God, nor of the means, nor of the proximate causes of our salvation; but he ascends higher, even to this, — why God, before the foundation of the world, chose only some and passed by others: and he declares, that God was led to make this difference by nothing else, but by his own good pleasure; for if any place is given to works, so much, he maintains, is taken away from grace. It hence follows, that it is absurd to blend foreknowledge of works with election. For if God chooses some and rejects others, as he has foreseen them to be worthy or unworthy of salvation, then the grace of God, the reward of works being established, cannot reign alone, but must be only in part the cause of our election. For as Paul has reasoned before concerning the justification of Abraham, that where reward is paid, there grace is not freely bestowed; so now he draws his argument from the same fountain, — that if works come to the account, when God adopts a certain number of men unto salvation, reward is a matter of debt, and that therefore it is not a free gift.
