In this current work, Foretastes of Heavenly Music: Johann Mattheson and Christoph Raupach on Music in Time and Eternity, Irwin provides translations and commentary for two 18th-century texts that illuminate the musico-theological foundation underlying the work of Lutheran composers such as Bach and Telemann. A Truth Lover's Clear Reasonings on Which the Correct Use of Music Rests (1717) by Christoph Raupach, with an introduction by Johann Mattheson, serves as a cumulative statement of Lutheran advocacy of music. Mattheson's Affirmation of Heavenly Music (1747) goes a step further in defending the reality of music in heaven and even the ultimate superiority of music over theology and sermons. | Foretastes Of Heaven In Lutheran Church Music Tradition by Joyce L.
