"When Christianity worked its way from the lower to the higher classes, its social sympathies became less democratic and fraternal, its language less simple, and its ideas more speculative, elaborate and remote. Origen felt he had to apologize for the homely Greek and the simple arguments of Jesus. Theology became an affair of experts. The first duty of the laymen was to believe with all their hearts what they could not possibly understand with all their heads."
