ANSWER: Some have thought that Paul used it for imparting religious instruction in Gal. 3:1 "before whose eyes Jesus Christ was depicted as crucified." It is better to understand Paul as saying that Christ crucified was vividly portrayed in his preaching. The comic cartoon was very early used as a weapon against Christ by pagans. Recently a wall of the barracks of the Pretorian guard, with which Paul was acquainted in his imprisonment at Rome, was laid bare, showing a rough cartoon of a cross to which a man with the head of a donkey was nailed. Beneath it a soldier is kneeling and these words are written, "Clovius worships his god." If the cartoon continues to be used, let the enemies of Christ have a monopoly of it. Let not professed Christians use it against one another.
