" One imagines that he might have understood the supreme value of Bach's vocal works - not primarily as objects or artefacts, but as individual visions of life and as priceless forms of communication with his fellow man. For this is what is so distinctive when we compare Bach's legacy to that of his forerunners and successors. Monteverdi gives us the full gamut of human passions in music, the first composer to do so; Beethoven tells us what a terrible struggle it is to transcend human frailties and to aspire to the Godhead; and Mozart shows the kind of music we might hope to hear in heaven. But it is Bach, making music in the Castle of Heaven, who gives us the voice of God - in human form. "

― John Eliot Gardiner , Bach: Music in the Castle of Heaven
