Mithras 3,000 BC - a dying, resurrected savior
Mithras was originally Persian. Before Rome. When the Christ myth was new Mithras and Mithraism were already ancient. Worshiped for centuries as God's Messenger of Truth, Mithras was long revered by the Persians (Zoroastrianism) and the Indians (see the Vedic literature).
Sadly there's a lot we don't know about this faith that comforted million of souls. Early Christians established the dominance of their religion by exterminating Mithras' faithful, razing His temples, burning His sacred texts.
Every year in Rome, in the middle of winter, the Son of God was born one more, putting an end to darkness. Every year at first minute of December 25th the temple of Mithras was lit with candles, priests in in white garments celebrated the birth of the Son of God and boys burned incense. Mithras was born in a cave, on December 25th, of a virgin mother.
He came from heaven to be born as a man, to redeem men from their sin. He was know as "Savior," "Son of God," "Redeemer," and "Lamb of God."
His followers kept the Sabbath holy, eating sacramental meals in remembrance of Him. The sacred meal of bread and water, or bread and wine, was symbolic of the body and blood of the sacred bull.
Baptism in the blood of the bull (taurobolum)
Mithraic rituals brought about the transformation and Salvation of His adherents -- an ascent of the soul of the adherent into the realm of the divine. From the wall of a Mithraic temple in Rome: "And thou hast saved us by shedding the eternal blood."
The great Mithraic festivals celebrated His birth (at the winter solstice) and His death and resurrection (at the spring solstice)
