With humor and ease, Fr. Michael Gaitley, MIC, 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 text, The ‘One Thing’ Is Three makes deep theology accessible to everyday Catholics. What’s more, it presents the familiar or forgotten in a way that’s new, exciting, and relevant. Ideal for the Year of Faith.
