With humor and ease, Fr. 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 an academic read, The ''One Thing'' Is Three makes deep theology accessible to everyday Catholics. What''s more, it makes even what''s familiar or forgotten new, exciting, and relevant. An ideal resource for the Year of Faith."This is the best example I have ever seen of "the new evangelization" in the form of a book for contemporary Catholics. It covers just about everything, yet slowly and clearly. If you wonder what God is doing in the Church today to convert and convince the modern world, read this book." — Peter Kreeft, Ph.D. Author, Catholic Christianity and Professor of Philosophy, Boston College
