The "One Thing" is Three: How the Most Holy Trinity Explains Everything

by Fr. Michael Gaitley, MIC

The Catechism of the Catholic Church teaches that, by far, the most important mystery of our faith is that Most Holy Trinity. It’s the mystery of our faith that’s the source of all the other mysteries and shines light on them all. With humor and ease, Father Michael Gaitley, MIC, deftly unlocks the "one thing," the key to the Church's wisdom, and the greatest mystery of the Catholic faith: the Most Holy Trinity.

Far from being a scholarly or academic read, The "One Thing" is Three makes deep theology accessible to every-day Catholics. It’s written as a crash course in Catholic theology written for busy people in a way that’s simple and easy to understand. What's more, it makes even what's familiar or forgotten appear in a way that's new, exciting, and relevant.

The Trinity  is often seen as esoteric, obscure, and outside of normal life. This book is meant to change that. It’s meant to bring the Trinity home to our hearts.
