Virtually all of the elements of Orthodox Christian rituals, from miter, wafer, water baptism, alter, and doxology, were adopted from the Mithra and earlier pagan mystery religions. The religion of Mithra preceded Christianity by roughly six hundred years. Mithraic worship at one time covered a large portion of the ancient world. It flourished as late as the second century. The Messianic idea originated in ancient Persia and this is where the Jewish and Christian concepts of a Savior came from.

The Gospel of Mark is written in the name of Mark, the disciple of the mythical Peter. (Peter is largely based on the pagan god Petra, who was door-keeper of heaven and the afterlife in Egyptian religion.) Even in Christian mythology, Mark was not a disciple of Jesus, but a friend of Paul and Luke. Mark was written before Matthew and Luke (c. 100 C.E.) but after the destruction of the Temple in 70 C.E., which it mentions. Most Christians believe it was written in c. 75 C.E. This date is not based on history but on the belief that an historical Mark wrote the gospel in his old age. This is not possible since the style of language used in Mark shows that it was written (probably in Rome) by a Roman convert to Christianity whose first language was Latin and not Greek, Hebrew or Aramaic. Indeed, since all the other gospels are written in the name of legendary characters from the past, Mark was probably written long after any historical Mark (if there was one) had died. The content of Mark is a collection of myths and legends put together to form a continuous narrative. There is no evidence that it was based on any reliable historical sources. Mark was altered and edited many times and the modern version probably dates to about 150 C.E. Clement of Alexandria (c. 150 C.E. - c. 215 C.E.) complained about the alternative versions of this gospel which were still circulating in his lifetime. (The Carpocratians, an early Christian sect, considered pederasty to be a virtue and Clement complained about their versions of Mark which told of Jesus's homosexual exploits with young boys!)
