The Aquinas Way Latest Edition Is Here!

Check out our most recent edition of The Aquinas Way! This issue is focused, appropriately enough given the time of year, on the Dominican pillar of prayer.

Inside you will find articles such as Fr. Charlie Bouchard's "A Life Lived in Prayer," profiles on several Aquinas community members and their prayer journeys, and "The Atrium as a Place of Prayer," which focuses on the Master of Arts in Pastoral Studies - Catechesis of the Good Shepherd (MAPS-CGS) program.
