Bernard of Clairvaux (1090-1153) was a Cistercian monk, famous in his own time as a theologian, statesman, and mystic. He was canonized as a saint in 1174 by Pope Alexander III and declared a Doctor of the Church by Pope Pius VIII in 1830. This perceptive introduction to the great theologian traces the major themes of his work in key writings such as On Grace and Free Choice, The Steps of Humility and Pride, On Loving God, Sermons on the Song of Songs, and Five Books on Consideration.
