"The same great change appears in community life. A new community, let us say, has been formed. It possesses many things that naturally belong to a well-ordered community; it has a drug-store, and a country club, and a school. “But there is one thing,” its inhabitants say to themselves, “that is still lacking; we have no church. But a church is a recognized and necessary part of every healthy community. We must therefore have a church.” And so an expert in community church-building is summoned to take the necessary steps. The persons who speak in this way usually have little interest in religion for its own sake; it has never occurred to them to enter into the secret place of communion with the holy God. But religion is thought to be necessary for a healthy community; and therefore for the sake of the community they are willing to have a church.
Whatever may be thought of this attitude toward religion, it is perfectly plain that the Christian religion cannot be treated in any such way. The moment it is so treated it ceases to be Christian. For if one thing is plain it is that Christianity refuses to be regarded as a mere means to a higher end. Our Lord made that perfectly clear when He said: “If any man come to me, and hate not his father and mother … he cannot be my disciple” (Lk. 14:26). Whatever else those stupendous words may mean, they certainly mean that the relationship to Christ takes precedence of all other relationships, even the holiest of relationships like those that exist between husband and wife and parent and child. Those other relationships exist for the sake of Christianity and not Christianity for the sake of them. Christianity will indeed accomplish many useful things in this world, but if it is accepted in order to accomplish those useful things it is not Christianity. Christianity will combat Bolshevism; but if it is accepted in order to combat Bolshevism, it is not Christianity: Christianity will produce a unified nation, in a slow but satisfactory way; but if it is accepted in order to produce a unified nation, it is not Christianity: Christianity will produce a healthy community; but if it is accepted in order to produce a healthy community, it is not Christianity: Christianity will promote international peace; but if it is accepted in order to promote international peace, it is not Christianity. Our Lord said: “Seek ye first the Kingdom of God and His righteousness, and all these things shall be added unto you.” But if you seek first the Kingdom of God and His righteousness in order that all those other things may be added unto you, you will miss both those other things and the Kingdom of God as well.
But if Christianity be directed toward another world, if it be a way by which individuals can escape from the present evil age to some better country, what becomes of “the social gospel”? At this point is detected one of the most obvious lines of cleavage between Christianity and the liberal Church. The older evangelism, says the modern liberal preacher, sought to rescue individuals, while the newer evangelism seeks to transform the whole organism of society: the older evangelism was individual; the newer evangelism is social.
This formulation of the issue is not entirely correct, but it contains an element of truth. It is true that historic Christianity is in conflict at many points with the collectivism of the present day; it does emphasize, against the claims of society, the worth of the individual soul. It provides for the individual a refuge from all the fluctuating currents of human opinion, a secret place of meditation where a man can come alone into the presence of God. It does give a man courage to stand, if need be, against the world; it resolutely refuses to make of the individual a mere means to an end, a mere element in the composition of society. It rejects altogether any means of salvation which deals with men in a mass; it brings the individual face to face with his God. In that sense, it is true that Christianity is individualistic and not social.
But though Christianity is individualistic, it is not only individualistic. It provides fully for the social needs of man. In the first place, even the communion of the individual man with God is not really individualistic, but social. A man is not isolated when he is in communion with God; he can be regarded as isolated only by one who has forgotten the real existence of the supreme Person. Here again, as at many other places, the line of cleavage between liberalism and Christianity really reduces to a profound difference in the conception of God. Christianity is earnestly theistic; liberalism is at best but halfheartedly so. If a man once comes to believe in a personal God, then the worship of Him will not be regarded as selfish isolation, but as the chief end of man. That does not mean that on the Christian view the worship of God is ever to be carried on to the neglect of service rendered to one’s fellow-men—“he that loveth not his brother whom he hath seen, is not able to love God whom he hath not seen”—but it does mean that the worship of God has a value of its own. Very different is the prevailing doctrine of modern liberalism. According to Christian belief, man exists for the sake of God; according to the liberal Church, in practice if not in theory, God exists for the sake of man."
