[Delphinium]

They are all good Christians, but believe that Mohammed was the Second Coming of Jesus Christ,

That would be false or demonic doctrine, going against the Bible.

Jay came to the knowledge that Jesus was the messiah from reading his own Bible. Christians and Jews believe in the same Bible.

[malakhi]

Christians and Jews believe in the same Bible.

We both believe in the inspiration of the Hebrew scriptures. However we don't "believe in the same Bible" because, first, Jews don't recognize the inspiration of the Christian scriptures, and second, because we don't interpret the Hebrew scriptures in the same way.
