Johann Sebastian Bach is one of the greatest composers in the history of western music. His work has nourished the spiritual lives of millions, regardless of culture, language or creed.; He has been called the "Fifth Evangelist," so effectively has he proclaimed the mystery of Christ in the language of art.; A devout Lutheran, he represents the mystical side of Protestantism -- those who move beyond moral teachings and the printed word, to encounter the living Word, face-to-face.
