Martin Luther (1483-1546)

"True it is that human wisdom and the liberal arts are nobel gifts of God, good and useful for all kinds of things, wherefore one cannot do without them in this life. But they can never thoroughly tell us what sin and righteousness are in the eyes of God, how we can get rid of sins, become pious and just before God, and pass from death into life. Wisdom divine and an art supreme are required to this; and one does nor find them in the books of any jurist or worldly-wise person, but in the Bible alone, which is the Holy Spirit's Book." — Martin Luther
