The catholic faith is defended through an analysis of several of the Gospel parables. The book discusses how these parables relate to both the Old Testament and everyday life. The Wedding Feast illustrates how faith in God and the just life are related. The Sower provides a discussion of the root causes of sin and the ways to overcome them. The Barren Fruit Tree discusses the mandate to act on the Gospel message, and the Prodigal Son shows how God bestows His infinite mercy upon those who repent and mend their ways.
