Bernard of Clairvaux: Sermons I on Conversion; Lenten Sermons on the Psalm "He Who Dwells"

The burgundian reformer abbot draws a picture of the perfect frontier bishop, and holds him up as a model for bishops everywhere.

Conversion is used here not in the modern sense of transferring from on ecclesiastical body to another, but in the patristic and monastic sense of metanoia, turning one's entire being wholly to God.
