It was no mere fabrication when the Early Church was accused by the world around it of atheism, and it would have been wiser for its apologists not to have defended themselves so keenly against this charge. There is a real basis for this feeling, current to this day, that every genuine proclamation of the Christian faith is a force disturbing to, even destructive of, the advance of religion, its life and richness and peace. It is bound to be so.
