Righteousness, as it was understood and taught by Christ, includes the two things which we often distinguish as religion and morality. It is right-doing, not only as between man and man, but as between man and God. The Lawgiver of the New Testament, like the lawgiver of the Old, has given to us two tables of stone. On the one He has written, "Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind "; and on the other, "Thou shalt love thy neighbour as thyself." In these two commandments the whole law is summed up, the whole duty of man is made known. It is well to emphasize this two-fold aspect of the truth at a time when we are often tempted to define religion wholly in the terms of morality, and, while insisting on the duties which we owe to each other, to forget those which we owe to God. If there be a God righteousness must surely have a meaning in relation to Him; it cannot be simply another name for philanthropy. Christ at least will not call that man just and good who does right to all except his Maker. In the Christian doctrine of the good life room must be found for God. At the present moment, however, it is the subject in its man-ward aspect that I wish specially to keep in view, partly because some limitation is obviously necessary, and partly also because it is this of which Christ Himself had most to say. I What, then, is Christ's idea of righteousness? In other words, what did He teach concerning the good life? Now here also, as in His teaching about God, Christ did not need to begin _de novo_. Those to whom He spoke had already their own ideals of duty and holiness. True, these were sadly in need of revision and correction. Nevertheless, such as they were, they were there, and Christ could use them as His starting-point. Consequently, therefore, we find His ideas of righteousness defined largely by contrast with existing ideas. "It was said to them of old time ... but I say unto _you_." This is the note heard all through the Sermon on the Mount. The contrast may be stated in two ways.
