And I do. But my Church teaches that men can be led to God by ways known only to Him. If your faith is weakened by praying with Jews or other non-Christians, then you shouldn't do it.
There is a WORLD of difference between "praying with Jews" (whom I believe God holds in His hand and protects) and bowing down before the altar of Christ beside Muslims, Hindus, Buddhists, Harry Potter wiccans and other assorted pagans.
I've read your posts for years, and I believe, in your heart, you know that's true.
Discernment counts.
