Excerpt from an interview conducted by Lee Strobel with Dr. Edwin M. Yamauchi.
"Mithraism was a late Roman mystery religion that was popular among soldiers and merchants, and which became a chief rival to Christianity in the second century and later...Mithraism as a mystery religion cannot be attested before about AD 90, which is about the time we see a Mithraic motif in a poem by Statius...Most of what we have as evidence of Mithraism comes in the second, third, and fourth centuries AD. That's basically what's wrong with the theories about Mithraism influencing the beginnings of Christianity."
Common parallels used by skeptics to "show" Christianity borrowed from Mithraism.
Claim: Mithras was born of a virgin.
Fact: Mithras was born out of a rock.
Claim: Mithras was born on December 25.
Fact: Irrelevant as we do not know when Jesus was born and the date of Christmas has changed over the years due to cultural surroundings.
Claim: Mithras was a great teacher with 12 disciples.
Fact: The legends claim that Mithras was a god, not a teacher.
Claim: Mithras sacraficed himself for world peace.
Fact: The legends claimed that Mithras killed a bull, not that he sacrificed himself.
Claim: Mithras was buried in a tomb and rose after three days.
Fact: We don't know anything about the death of Mithras. There are many monuments but almost no textual evidence and with no death there is obviously no resurrection.
