Thus far we have considered Christ's idea of righteousness only in contrast with other ideas. When we seek to define it in itself we fall back naturally on the words of the two great commandments which have already been quoted: "Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind;" and "Thou shalt love thy neighbour as thyself." Righteousness, Christ says, is love, love to God and love to man. But to them of old time it was said, "Thou shalt love thy neighbour." Where, then, is the difference between the old commandment and the new? It lies in the new definition of "neighbour." The old law which said, "Thou shalt love thy neighbour," said also, "and hate thine enemy"; which meant that some are and some are not our neighbours, and that toward those who are not love has no obligations. But Christ broke down for ever the middle wall of partition, and declared the old distinction null and void. In His parable of the Good Samaritan He taught that every man is our neighbour who has need of us, and to whom it is possible for us to prove ourselves a friend. As we have opportunity we are to do good unto all men. The same lesson with, if possible, still greater emphasis, Christ taught in the Upper Room: "A new commandment I give unto you, that ye love one another; even as I have loved you, that ye also love one another." A love that goes all the way with human need, that gives not itself by measure, that is not chilled by indifference, nor thwarted by ingratitude, that fights against evil until it overcomes it--such was the love He gave, and such is the love He asks. And in that command all other commands are comprehended. Christ might have made His own the daring word of St. Augustine, "Love, and do what you like."
