I belong to a sect within Islam, called the Ahmadiyya Movement in Islam. Where we differ from mainstream Islam are two things. We don't believe that Jesus died on the cross or that he was replaced by a look-a-like,
while the real Jesus ascended into the heavens, who shall return one day. We believe that he survived death on the cross, escaped to Kashmir, where he died a natural death.The other differense is that we believe the 2nd coming, i.e. the Messiah that everyone is waiting for has already come. He was the Krishna of the Hindus, the Messiah of the Christians and the Jews, the Buddha of the Budhists, and the Imam-al-Mahdi of the Muslims and the Messiah.
If someone's more interested, just hollar at me, I'll gladly answer any questions
