Mithraism

Mithraism, a religion predating Christianity and popular in the Roman Empire, seems to have had many similarities to Christianity as we know it today-- followers of it worshiped a resurrecting deity born of a virgin and tended to by shepards, and who had also acended to the heavens, promising to come again, practiced baptism and partook of a sacred meal of bread and wine, called themselves "reborn" in Mithrai, the "Christ" (a Hellenistic term) and "Son of God", and as well worshiped on Sundays. They also discouraged women, had a conplicated hierarchy, had had priests they called 'Fathers', and celebrated his birth on the Winter Solstace, usually December 25.
This now dead religion seems to have a large link to the early formation of the Christian church-- Constantine himself was a believer of Mithra before converting to Christianity. So, while providing data on the subject (hopefully with links) what do you think is the connection between these two faiths?
