How does the mainstream Christian view of the physical body differ from that presented in The Gospel of Thomas?

What is the value of the physical body in mainstream Christianity? Sometimes it seems to be very negative and to encourage one to concentrate primarily or even almost solely on the spiritual realm. Other times looking after the body with Biblical references to it as a temple for the holy spirit and the like. What is the mainstream Christian view of the physical body? Specifically, I'd like to compare and contrast the understanding of the body as found in the Gospel of Thomas with Nicene Christianity. Are the two incompatible?
