Yes I know, it's Wikipedia, but I think Wikipedia is still fairly reliable for basic facts.

No. Mithras is the Roman sun god. Mithra is the Persian god. Mithras is the Roman adaptation of Mithra.
Ok I was wrong about that as well but Mithras worship didn't come into practice in Rome until the late 1st century AD, well after the establishment of Christianity.
