Mithra and Christ
Over the centuries—in fact, from the earliest Christian times—Mithraism has been compared to Christianity, revealing numerous similarities between the two faiths' doctrines and traditions, including as concerns stories of their respective godmen. In developing this analysis, it should be kept in mind that elements from Roman, Armenian and Persian Mithraism are utilized, not as a whole ideology but as separate items that may have affected the creation of Christianity, whether directly through the mechanism of Mithraism or through another Pagan source within the Roman Empire and beyond. The evidence points to these motifs and elements being adopted into Christianity not as a whole from one source but singularly from many sources, including Mithraism.

Thus, the following list represents not a solidified mythos or narrative of one particular Mithra or form of the god as developed in one particular culture and era but, rather, a combination of them all for ease of reference as to any possible influences upon Christianity under the name of Mitra/Mithra/Mithras.
Mithra has the following in common with the Jesus character:
Mithra was born on December 25th of the virgin Anahita.
The babe was wrapped in swaddling clothes, placed in a manger and attended by shepherds.
He was considered a great traveling teacher and master.
He had 12 companions or "disciples."
He performed miracles.
As the "great bull of the Sun," Mithra sacrificed himself for world peace.
Mithra ascending to heaven in his solar cart, with sun symbolHe ascended to heaven.
Mithra was viewed as the Good Shepherd, the "Way, the Truth and the Light," the Redeemer, the Savior, the Messiah.
Mithra is omniscient, as he "hears all, sees all, knows all: none can deceive him."
He was identified with both the Lion and the Lamb.
His sacred day was Sunday, "the Lord's Day," hundreds of years before the appearance of Christ.
His religion had a eucharist or "Lord's Supper."
Mithra "sets his marks on the foreheads of his soldiers."
Mithraism emphasized baptism.
December 25th Birthday
"The similarities between Mithraism and Christianity have included their chapels, the term "father" for priest, celibacy and, it is notoriously claimed, the December 25th birthdate. Over the centuries, apologists contending that Mithraism copied Christianity nevertheless have asserted that the December 25th birthdate was taken from Mithraism. As Sir Arthur Weigall says:
December 25th was really the date, not of the birth of Jesus, but of the sun-god Mithra. Horus, son of Isis, however, was in very early times identified with Ra, the Egyptian sun-god, and hence with Mithra..."
