Pope John XXIII said that "Christian doctrine should be guarded and taught more efficaciously." He also said we need to "Discover ways of teaching the faith more effectively." Largely in response to these types of directives from our Catholic Church leaders, Catholic author and guest speaker, Sean McVeigh, has written The Conversion Book: How to Effectively Help Protestants Convert to Catholicism. It provides a unique, modern, and powerful approach to Catholic evangelization. The Conversion Book is intended for adult and young adult Catholics of all levels of religious and evangelization experience. Whether the reader is a seasoned evangelist or someone who has never talked to another person about God before, The Conversion Book is specifically designed to help that person improve his or her ability to effectively share his or her belief in Jesus Christ and the teachings of Jesus' Holy Catholic Church. As each reader discovers very early in this publication, the process of training for effective evangelization begins with an intense focus on one's own prayer life and spiritual discernment. After the individual is spiritually prepared, Sean takes each reader through a very specific and systematic approach to evangelization that is sure to surprise many of the evangelizer's listeners. Ultimately, through using this approach, there will be many Protestants who will realize their need to leave some of their current theological ways of thinking behind in order to more fully embrace the truth that Jesus wants them to know and follow. The author believes there will be a massive exodus of people leaving the Protestant belief system in order to become Catholic once they have had the truth presented to them in an extremely effective and mature way. However, this exodus will only happen if Catholics at large intensify their evangelization efforts while implementing the most effective methods possible in helping Protestants convert. Lastly, this publication is a great resource for Protestants who are interested in learning more about the core differences between the Catholic and Protestant faiths.
