James F. Keenan, SJ, is one of the church's most vibrant, influential, and sensible theologians. His work on mercy and compassion, as well as his larger work on moral theology, has had a profound influence on my own life. His writings, based on Scripture, tradition, and experience, are accessible, inviting, faithful, provocative, and inspiring. Father Keenan has helped to teach me how to think about life, and, more importantly, how to live.
