This work contains several examinations of conscience from Catholic classic books. It also contains Saint Alphonsus' instruction on Confession from his Catechism. Further notes are contained on modern sins and on conversion. One examination of conscience distinguishes between mortal and venial sins. In preparing for the Sacrament of Confession it is easy to get into a rut, using the same examination of conscience for every Confession. These examinations are from various sources and are provided to help us shake up our spiritual life. By varying our routine, we can more easily identify our sins and bring them to the tribunal of Penance where we can present them before the Divine Physician and His human representative, the duly authorized priest. In this way our confessor can prescribe the remedies for our sins, so that we can heed the advice of Jesus: "Go now and sin no more, lest some worse thing happen to you." (John 5:14) Since these come from timeless older works, they have been updated by this author to include the sins that are so easily committed with modern technology, such as radio, television, moves, the computer and the internet. We hope all will benefit from the sage advice contained in this book.
