"Confirmands today are like young soldiers marching to war, the war of Jesus Christ against the gods of this world. It is a war that demands the commitment of one's whole life. Is not God, our Lord, worthy of this struggle? Idolatry and cowardice confront us on all sides, but the direst foe does not confront us, he is within us. 'Lord, I believe, help thou mine unbelief.'"It was 1938.
