Self-taught composer plus avid collector of Classical music and scores
The most important impact on religious music in Europe following the Protestant Reformation is that composers of Protestant music could now write texts in their own vernacular. Beforehand, the Roman Catholic Church dominated much of Europe and it was only permissible to give mass and write music in Latin. Following the Reformation, German Protestants could now do their services in German, for example, since they no longer adhered to the Roman Catholic Church. This tradition carried beyond the Renaissance era of course, with such famous examples as Bach's chorales and Brahms's German Requiem.
