Vatican II issued an urgent call for the laity to take a more active role in the life of the Church. What should the life of the Christian believer be like? How are average lay Christians called to help save the world? How does theology fit into the picture? One of Sheed's most popular books, this is the ideal volume for helping the layman to take a more active role in the Church by showing him the practical aspects of theology and the role it has in the life of Christian believers. Logic, clarity, simplicity and common sense permeate this eminently readable book. Drawing from his fifty years of street-corner preaching, as well as his long career as author, lecturer and publisher, Sheed understands and communicates better than anyone the importance of theology and its relationship to living sanely in today's world. A brilliant synthesis of the Catholic view of life. " Of Sheed's many books, this is my favorite, not just because it includes the clearest explanation of the Trinity ever put on paper, but because it proves that only the Catholic view of reality can satisfy our mental hunger.
