The force of the "Age of Reason" is not in its theology, though this ethical variation of Deism in the direction of humanity is of exceeding interest to students who would trace the evolution of avatars and incarnations. Paine's theology was but gradually developed, and in this work is visible only as a tide beginning to rise under the fiery orb of his religious passion. For abstract theology he cares little. "If the belief of errors not morally bad did no mischief, it would make no part of the moral duty of man to oppose and remove them." He evinces regret that the New Testament, containing so many elevated moral precepts, should, by leaning on supposed prophecies in the Old Testament, have been burdened with its barbarities. "It must follow the fate of its foundation." This fatal connection, he knows, is not the work of Jesus; he ascribes it to the church which evoked from the Old Testament a crushing system of priestly and imperial power reversing the benign principles of Jesus. It is this oppression, the throne of all oppressions, that he assails. His affirmations of the human deity are thus mainly expressed in his vehement denials. This long chapter must now draw to a close. It would need a volume to follow thoroughly the argument of this epoch-making book, to which I have here written only an introduction, calling attention to its evolutionary factors, historical and spiritual. Such then was the new Pilgrim's Progress. As in that earlier prison, at Bedford, there shone in Paine's cell in the Luxembourg a great and imperishable vision, which multitudes are still following. The book is accessible in many editions. The Christian teacher of to-day may well ponder this fact. The atheists and secularists of our time are printing, reading, revering a work that opposes their opinions. For above its arguments and criticisms they see the faithful heart contending with a mighty Apollyon, girt with all the forces of revolutionary and Royal Terrorism. Just this one Englishman, born again in America, confronting George III. and Robespierre on earth and tearing the like of them from the throne of the universe! Were it only for the grandeur of this spectacle in the past Paine would maintain his hold on thoughtful minds.
