" As a teacher of future preachers, Bonhoeffer devoted time to making written comments on students’ manuscripts, but he did not allow negative criticism in class when a student had just presented an early effort at a sermon. The future preacher too must feel accepted, must receive Christ’s hope and love, in order to go forward and take them to others. Wherever that person’s ministry might lead in the future, Christ’s church-community must surround with prayer, sustain and uphold his servant, beginning in the seminary. "
