Blessed Columba Marmion was much sought after throughout his life by those with questions on faith, prayer, or temptation; and his striking powers of spiritual counsel are on full display in this collection of letters exchanged between him and various members of the faithful. Union with God reveals a man speaking not only from the experience of the mind, but also from the depths of his own soul. These letters find Marmion employing his vast theological knowledge to give advice that is at once practical and profound, simple and extraordinary. The attentive reader will quickly understand why even popes and bishops looked to him for inspiration and counsel. Edited and arranged by Dom Raymond Thibaut, Union with God joins such classics as Christ the Life of the Soul, Our Way and Our Life, and With Christ as an exemplary addition to the publications of Marmion's writings now available from Angelico Press.
