I used this book as part of our archdiocesan deacon formation program for a course I was teaching on RCIA, Baptism, and Confirmation. As I researched statistic and found that about 2/3 of RCIA participants leave the Church after 1 year, I realized we weren't doing it right. Helping my students understand the struggles of someone who is new to the church is essential and this book can serve to open our eyes to why mystegogia is not optional. Shaun gave us a great point from which to start our journey as the class discussed the appropriate content for the RCIA as an "apprenticeship in the faith." It is a basic manual for day to day struggles, navigating the insider language we use in the Church, and understanding a lot of the things we often neglect as we prepare people for the sacraments. Best of all, it gives this to us from the perspective of someone who has been there. This book is full of the things people are hungry for as they begin a new spiritual journey. It would be great for a high school class, people returning to the faith, or for new Catholics but also for the average Catholic who just wants to mature their faith or read a brief refresher. As a deacon myself, I found it was a good reminder of a lot of the things we often take for granted. It allowed me to remember a simpler time in my faith and reading it was just good for the soul. I will agree with other readers, this is not a straight read. It's a better reference book, a book read in pieces, etc... it contains a lot of suggestions for self-mastery and even one of these topics can take a person a long time to work out. With that stated, it still does what it sets out to do, which is to fill in those gaps in so many RCIA programs around the world.
