The contention that any beliefs, let alone faith, can be certain is anathema to our postmodern culture. Yet it has been the perennial teaching of the Church that, by means of our natural reason, we can attain certain knowledge of the existence of God. This book builds upon the fact that there is an intrinsic, formative principle within thought—namely, being. Such a fact will be beneficial to anyone seeking to ground a clear and certain understanding of the nature of faith. Those unfamiliar with the idea of analogy of being will be intrigued by this concept’s depth and compass. After securing this idea within natural theology, Barry R. Pearlman goes on to thread the analogy of being through cosmology, Christology, the nature of the Church, and the moral and spiritual life. This book is designed to take the reader from a situation of doubt, then through faith and the understanding of virtue, to arrive finally at the threshold of contemplation.
