It is God's will that the Church should be coterminous with society, and that the unity of life thus produced should make the "communion of saints" a reality on earth and not a mere theory. Past years have seen much earnest straining to gain a truer conception of God, that fellowship with and love for Him might be according to His will. All this theological effort will be lost, unless it is followed up by a no less strenuous effort to make the brotherhood of man a fact. The Master gave a new commandment of love, a commandment new not in essence but rather in intensity and comprehension. After the injunction to love God comes the equally unequivocal injunction to love man--"Thou shalt love thy neighbour as thyself." That is to say, personality whether in ourselves or in others is to receive the highest reverence and consideration, and that without any partiality. Humanity being full of diversity, this commandment requires a most thorough and intelligent study of society and its elements. Heresies concerning God have been and are destructive of unity; but heresies concerning man are productive of almost equal mischief. If the first part of the commandment of love calls us to a study of theology, the second demands a study of sociology--an old science under a new name. It is worth while noting that the Apostle who earned the name of "the Divine," or as we would say "the Theologian," by reason of his familiar acquaintance with the deep things of God, was the same who felt that the appeal most worth urging with the scant breath of extreme old age was, that men should love one another; and he repeats this simple phrase until the world wonders--"My little children, let us not love in word, neither in tongue, but in deed and in truth." But it must never be forgotten that human fellowship and friendship must under the best of conditions be sectional and shallow, and under the worst, disastrous, unless it be "in Christ," that is, in God. The true ideal of human fellowship is realized only thus. And it is such a unity as would be the outcome of fellowship in Christ, for which the Master prayed at the last. Ecclesiastical unity does not necessarily produce unity of life, though the latter must include the former in some true sense. Christian unity has a twofold basis, the love of God and the love of man. This differentiation in the commandment of love, is of Christ's own making, and cannot be ignored by His followers.
