The Catechism Explained by Fr. Francis Spirago, edited by Fr. Richard F. Clarke, S.J., is such a well-known Catholic classic that it hardly needs any introduction. The book was written for three specific uses—to serve the preacher as a sourcebook for sermons, the catechist as a thorough explanation of the catechism, and parents as a complete statement of the entire Faith, to assist them in instructing their children. Written to achieve these objectives, the book specifically does not contain technical language so that it is not difficult to understand. But it is large, it is thorough, and it is interesting! Plus, there is no other book quite like it.
