Why does Islamic tradition identify the Prophet Idris (the Biblical Enoch) with Hermes Trismegistus? What is the significance of the number 144,000 (Rev 7:4)? Can you give a quick run-down on the history of ideas of salvation in Christianity? Could you please give a survey of the topic of Christology, including both orthodox and heterodox perspectives? I have read that early opponents of Christianity claimed Jesus was a magician who learned his tricks in Egypt. Who were these opponents?
