The "One Thing" is Three by Michael E. Gaitley, MIC

The "One Thing" is Three is written for everyone. The conversational tone has an appeal that invites the reader into the journey of life. I highly recommend this book for anyone who loves the Church and seeks a deeper understanding of her teachings. Filled with references to Vatican II and Pope John Paul II, this book will enrich your belief in God's plan of salvation, and your love of the Most Holy Trinity.

Dr. Peter Kreeft, PHD: "WARNING: This book is dangerous. It brims with wisdom and wonder, and with enthusiastic and infectious joy. This is the very best example I have ever seen of the "New Evangelization" in the form of a book for contemporary Catholics."


Fr. Michael Gaitley, MIC
