Christianity thinks of human individuals not as mere members of a group or items in a list, but as organs in a body—different from one another and each contributing what no other could. When you find yourself wanting to turn your children, or pupils, or even your neighbours, into people exactly like yourself, remember that God probably never meant them to be that. You and they different organs, intended to do different things. On the other hand, when you are tempted not to bother about someone else’s troubles because they are ‘no business of yours’, remember that though he is different from you he is part of the same organism as you. If you forget that he belongs to the same organism as yourself you will become an Individualist. If you forget that he is a different organ from you, if you want to suppress differences and make people all alike, you will become a Totalitarian. But a Christian must not be either a Totalitarian or an Individualist.
