20. Chap. XI.

This, moreover, is the reason why the law of the Sabbath is placed third among the three commandments of the Decalogue which declare our duty to God (for the other seven relate to our neighbour, that is, to man; the whole law hanging on these two commandments). ¹ The first commandment, in which we are forbidden to worship any likeness of God made by human contrivance, we are to understand as referring to the Father: this prohibition being made, not because God has no image, but because no image of Him but that One which is the same with Himself, ought to be worshipped; and this One not in His stead, but along with Him. Then, because a creature is mutable, and therefore it is said, "The whole creation is subject to vanity," ² since the nature of the whole is manifested also in any part of it, lest any one should think that the Son of God, the Word by whom all things were made, is a creature, the second commandment is, "Thou shalt not take the name of the Lord thy God in vain." ³ And because God sanctified the seventh day, on which He rested, the Holy Spirit--in whom is given to us that rest which we love everywhere, but find only in loving God, when "His love is shed abroad in us, by the Holy Ghost given unto us" ⁴ --is presented to our minds in the third commandment, which was written concerning the observance of the Sabbath, not to make us suppose that we attain to rest in this present life, but that all our labours in what is good may point towards nothing else than that eternal rest. For I would specially charge you to remember the passage quoted above: "We are saved by hope; but hope that is seen is not hope." ⁵
