This book is presented simply to those souls who desire to hear and follow the voice of God, which is the inspiration of grace. Many vocations sadly are lost today. This book talks about the easy signs to discern whether a soul has a vocation to the religious life or to the priesthood. There are definitions in the appendix to help a possible confused soul to understand the vocabulary they may not be acquainted with. There are many Saints that have looked upon the religious life as espousing Jesus Christ, rather than losing their virginity. As those Saints have said: "Why would I marry a mere peasant than a King?" The king they refer to is the King of Kings, Jesus Christ. Why should a young lady today not do the same? Why not espouse Christ, who is infinite purity? Why stain your soul with sin? St. Alphonsus writes: "a single bad book will be sufficient to cause the destruction of a monastery." Pope Pius XII wrote in 1947 at the beatification of Blessed Maria Goretti: "There rises to Our lips the cry of the Saviour: 'Woe to the world because of scandals!' (Matthew 18:7). Woe to those who consciously and deliberately spread corruption-in novels, newspapers, magazines, theaters, films, in a world of immodesty!" We at St. Pius X Press are calling for a crusade of good books. We want to restore 1,000 old Catholic books to the market. We ask for your assistance and prayers.
