12. This is the token of the covenant. A sign is added to the promise, in which is exhibited the wonderful kindness of God; who, for the purpose of confirming our faith in his word, does not disdain to use such helps. And although we have more fully discussed the use of signs in Genesis 2:1, yet we must briefly maintain, from these words of Moses, that it is wrong to sever signs from the word. By the word, I mean not that of which Papists boast; whereby they enchant bread, wine, water, and oil, with their magical whisperings; but that which may strengthen faith: according no the Lord here plainly addresses holy Noah and his sons; he then annexes a seal, for the sake of assurance. Wherefore, if the sacrament be wrested from the word, it ceases to be what it is called. It must, I say, be a vocal sign, in order that it may retain its force, and not degenerate from its nature. And not only is that administration of sacraments in which the word of God is silent, vain and ludicrous; but it draws with it pure satanic delusions. Hence we also infer, that from the beginning, it was the peculiar property of sacraments, to avail for the confirmation of faith. For certainly, in the covenant that promise is included to which faith ought to respond. It appears to some absurd, that faith should be sustained by such helps. But they who speak thus do not, in the first place, reflect on the great ignorance and imbecility of our minds; nor do they, secondly, ascribe to the working of the secret power of the Spirit that praise which is due. It is the work of God alone to begin and to perfect faith; but he does it by such instruments as he sees good; the free choice of which is in his own power.
