I will repeat, the Qur'an does not contain a single prophesy. You have not refuted what I posted Mon Jun 04, 2007 05:21 pm.
Now, the 2nd Treatise of Seth is from Gnosticism, a sect founded in Greek pagan religious philosophy that tried to pervert the teachings of Jesus. Had this cult survived to the 7th century Muhammad and his intolerance would have resulted in Muhammad being reviled. Gnostics taught tolerance and viewed any religion that was intolerant of Greek "wisdom" a perversion. There is also a Gnostic "gospel that states Jesus initiated young men into the sexual mysteries of phallic worship. Judaism, Christianity, and Islam condemn homosexuality, which was tolerated by Roman and Greek cultures. Therefore, it is a bit hypocritical of Muslims to appeal to a sect that promotes what Islam condemns in your attempt to show the crucifixion and resurrection never happened and the Qur'an is true.
Christian Gnosticism was the first heresy that Christianity had to deal with, and taught among other errors that Thomas was Jesus' twin brother.
This idea of Thomas as a twin messiah appears to have been embraced by many of the early Christian groups. There was a Syrian sect called the “Christians of St. Thomas”, and similar sects throughout the Middle and Far East. This is largely because Thomas is believed to have traveled throughout the East spreading the gospel after Jesus’ death, and his supposed tomb can be found in India. Several of these sects believed that he was literally Jesus’ twin brother. Many people were already receptive to this idea, because the archetype of twin gods or sons of God is one that can be found in the legends of many cultures throughout the world. In Edessa, Turkey, where The Acts of Thomas were written, the worship of the twin gods Momim and Aziz was replaced seamlessly by that of Thomas and Jesus.

If you accept the 2nd Treatise of Seth is true, you have to accept the entirety of Gnosticism is true, which means you also have to reject Muhammad and Islam or admit you are resorting to quote mining in an attempt to justify accepting a false prophet.
