699. What true Christian does not acknowledge that these two sacraments are holy, and in Christendom are even the most holy things of worship? But who knows wherein their holiness resides, or whence it is? In the institution of the holy supper all that is known from the natural sense is that the flesh of Christ is given to eat, and His blood to drink, and that the bread and wine stand for these. From this who can think otherwise than that it is holy merely because it is commanded by the Lord? Therefore the most sagacious men in the church have taught that the element becomes a sacrament when the Word is added to it [in the service]. But as such a source of holiness does not satisfy the understanding, and there is no evidence of it in the element or symbols, but is only a matter of memory, so the sacrament is observed by some from a confidence that by means of it their sins are forgiven, by others because they believe it sanctifies, by others because it strengthens their faith, and thus promotes salvation; while those who think lightly of it, come to it simply because they have been accustomed to do so from childhood; and others neglect it because they see no reason in it. But the impious turn away from it, saying to themselves, "What is it but a ceremony stamped with holiness by the clergy? For what is there in it but bread and wine? And what is it but a fiction that the body of Christ which hung upon the cross, and His blood which was then poured out, are distributed to the communicants along with the bread and wine?" And so on.
