But to understand the words of our Saviour, we must observe that the law of Moses is taken in a double sense, either as containing some principles in common with human laws, such as imposing restraint upon human crimes by the dread of exemplary punishments. Heb. ii. 2. And in this manner maintaining civil society among the Jewish people: for which reason it is called, Heb. vii. 16, the law of a carnal commandment, and Rom. iii. 17. the law of works: or it may be taken in another sense, comprehending the peculiar sanctions of a divine law, requiring purity of mind, and certain actions, which might be omitted without temporal punishments. In this sense it is called a spiritual law, giving life to the soul. The teachers of the law, and the Pharisees considering the first part as sufficient, neglected to instruct the people in the second and more important branch, deeming it superfluous. The truth of this may be proved, not only from our own writings, but from Josephus also, and the Jewish Rabbis. Respecting this second part we may observe, that the virtues which are required of Christians, are either recommended or enjoined to the Hebrews, but not enjoined in the same degree and extent as to Christians. Now in both these senses Christ opposes his own precepts to the old law. From whence it is clear, that his words contain more than a bare interpretation of the Mosaic law. These observations apply not only to the question immediately in hand, but to many others; that we may not rest upon the authority of the Mosaic law farther than is right.
