Conversational sermonizing, as practised by Dean Pike, of the New York Cathedral, and various collaborators, is a very effective way of presenting the Christian truths and insights which are always under attack--never more so than in our day. Here we have a series of trialogues as they were preached in the Cathedral pulpit and also broadcast over NBC radio network. In them, an ordinary man debates the seven deadly sins with representatives of God and Satan. He faces anger, pride, envy, self- indulgence, hypocrisy; and the temptation and the divine-human resources to meet it are made vivid and clear in a rapid cross-fire of conflicting advice. It is a book of great usefulness to both clergy and laymen, a lively surprise to those who think of theology as dull or dead.
