Love is, in short, a religious attitude. There are circumstances in which it may prosper without the inspiration of religion. In the family relation and in other intimate circles proximity and consanguinity may prompt men to regard human beings as essentially good, and direct experience validate their faith. That is why Jesus discounted love in the family as a religious achievement. “If ye love those who love you, what thanks have ye?” In the secondary relations, which are no longer secondary in the matter of importance to human welfare, the matter is not so simple. In these only a sublime assumption will persuade men to embark upon the adventure of brotherhood, and only a robust and constantly replenished faith will inure them against inevitable disappointments. The religious interpretation of the world is essentially an insistence that the ideal is real and that the real can be understood only in the light of the ideal. Since the family relation is the most ethical relation men know, religious faith interprets all life in terms of that relation. In view of many of the facts of history which seem to reveal the world of man as but a projection of the world of nature in which animal fights with animal and herd with herd, this kind of interpretation is superficially too absurd to persuade a highly sophisticated intelligence. It is the truth which is withheld from the wise and revealed to babes. Yet it is the truth without which men will not be able to build a peaceful society. It is the truth which even the physical facts of a highly complex civilization, in which space and time are being annihilated, are conspiring to make true. The races and groups of mankind are obviously not living as a family; but they ought to. And as the necessity becomes more urgent the truth of the ideal becomes more real.
