"Almost All" (90 - 95%) of J. S. Bach's compositions are, musically, based on various "Protestant Hymns". This is a musical and compositional fact, when one understands how to analyse his compositions from a musical standpoint. For this reason, some Jewish people consider his music to be Christian music. As I understand, it may not be even heard by some religious Jews.
On the other hand, there is not a trace of anti-semitism in any of his oratorios, songs, concertos, and orchester pieces. In Israel his music is often performed. Isaac Sterns, one of the greatest violinists ever to live, an Israeli played J.S. Bach's music on numerous occasions - Jacqueline Du Pre, as well. The compositions of J.S. Bach are often used as part of a musician's and singer's basic training for both technique and musicality (The Preludes, Cantatas, orchestral suites for some examples only).
So, can Jews listen to and perform this music or not?
(This is more of a Philosophical Question, than a religious one.)
