In the third place, a true Christian church will be radically ethical...it will be ethical in the sense that it will cherish the hope of true goodness in the other world, and that even here and now it will exhibit the beginnings of a new life which is the gift of God.
That new life will express itself in love. Love will overflow, without questions, without calculation, to all men whether they be Christians or not; but it will be far too intense a passion ever to be satisfied with mere philanthropy. It will offer men simple benefits; it will never pass coldly by on the other side when a man is in bodily need. But it will never be content to satisfy men's bodily needs; it will never seek to make men content with creature comforts or with the coldness of a vague natural religion. Rather will it seek to bring all men everywhere, without exception, high and low, rich and poor, learned and ignorant, compatriot and alien, into the full warmth and joy of the household of faith.J.
