They propose love for humanity alone, apart from love for God.
But such a love cannot exist. There is no motive to produce it. Christian love is the result only of the Christian conception of life, in which the aim of life is to love and serve God.
The social conception of life has led men, by a natural transition from love of self and then of family, tribe, nation, and state, to a consciousness of the necessity of love for humanity, a conception which has no definite limits and extends to all living things. And this necessity for love of what awakens no kind of sentiment in a man is a contradiction which cannot be solved by the social theory of life.
The Christian doctrine in its full significance can alone solve it, by giving a new meaning to life. Christianity recognizes love of self, of family, of nation, and of humanity, and not only of humanity, but of everything living, every thing existing; it recognizes the necessity of an infinite extension of the sphere of love. .But the object of this love is not found outside self in societies of individuals, nor in the external world, but within self, in the divine self whose essence is that very love, which the animal self is brought to feel the need of through its consciousness of its own perishable nature.
The difference between the Christian doctrine and those which preceded it is that the social doctrine said "Live in opposition to your nature [understanding by this only the animal nature], make it subject to the external law of family, society, and state." Christianity says "Live according to your nature [understanding by this the divine nature]; do not make it subject to anything— neither you (an animal self) nor that of others—and you will attain the very aim to which you are striving when you subject your external self."
