Catholics are bound to observe the laws of the Church, in addition to the Ten Commandments. Many of these additional laws have been long established and observed by the Faithful for centuries. The Precepts of the Church are not all inclusive in terms of the rules for living a Catholic life. There are other laws that Catholics are bound to observe that are not listed in the Precepts of the Church. The Precepts of the Church are the six principal ones, that is, the six ones with which Catholics should ordinary be concerned, since they ordinarily occur in a person's life. Through this book, Mr. Plese studies the precepts in depth to understand the need for the precepts, what the precepts require of us, and why they are so important.
