1932. Widtsoe, a member of the Council of the Twelve Apostles, writes: A rational theology, as understood in this volume, is a theology which 1) is based on fundamental principles that harmonize with the knowledge and reason of man, 2) derives all of its laws, ordinances and authority from the accepted fundamental principles, and 3) finds expression and use in the everyday life of man. In short, a rational theology is derived from the invariable laws of the universe, and exists for the good of man. This volume is an exposition; it is not an argument. The principles of the Gospel, as held by the Church of Jesus Christ of Latter-Day Saints, are stated briefly, simply and without comment, to show the coherence, reasonableness and universality of the Gospel philosophy.
