Although Judaism and Christianity are rather incompatible too (either Jesus is the messiah, or he is NOT) they aren’t as incompatible as Islam and Christianity. After all, no ancient Jewish text speaks against Jesus, because he hadn’t been born yet. But Islam says very clearly he is NOT the son of God. Can’t have it both ways, folks.
Putting the Koran in churches is like putting Mein Kampf in synagogues.
