Thoughts Matter takes up the teaching of influential fouth-century monk, John Cassian, who is largely credited with bringing the practices of Christian monasticism to the West. Cassian taught that real intimacy with God in prayer demands renouncing one’s former way of life, the thoughts belonging to that former way of life, and one’s very idea of God. In Thoughts Matter, Sr. Mary Margaret Funk focuses on the second of these: renouncing the thoughts belonging to one’s former way of life. Her eight chapters focus on different thoughts—food, sex, anger, dejection, acedia (profound weariness of the soul), vainglory (taking credit for good actions), and pride.
Funk explains well how failure to control these thoughts can undermine our spiritual life, and she instructs readers on how effectively to overcome these thoughts and to focus instead on thoughts in harmony with God’s will. The result is an experience of joy, hope, and freedom from enslavement to our appetites.
