Not really conversant with the Horus-Jesus similarities, and I have no desire in getting into them; however, let me present the findings of two scholars, Timothy Freke and Peter Gandy, who, looking into the Osiris-Dionysus/Jesus connection, and the machinations of the Catholic Church, said:
"The more we studied the various versions of the myth of Osiris-Dionysus, the more it became obvious that the story of Jesus had all the characteristics of this perennial tale. Event by event, we found we were able to construct Jesus' supposed biography from mythic motifs previously relating to Osiris-Dionysus:
Osiris-Dionysus is God made flesh, the savior and "Son of God."
His father is God and his mother is a mortal virgin.
He is born in a cave or humble cowshed on December 25 before three shepherds.
He offers his followers the chance to be born again through the rites of baptism.
He miraculously turns water into wine at a marriage ceremony.
He rides triumphantly into town on a donkey while people wave palm leaves to honor him
He dies at Eastertime as a sacrifice for the sins of the world.
After his death he descends into hell, then on the third day he rises from the dead and ascends to heaven in glory.
His followers await his return as the judge during the last days.
His death and resurrection are celebrated by a ritual of bread and wine, which symbolize his body and blood.
These are just some of the motifs shared between the tales of Osiris-Dionysus and the biography of Jesus. Why are these remarkable similarities not common knowledge? Because, as we were to discover later, the early Roman Church did everything in its power to prevent us perceiving them. It systematically destroyed Pagan sacred literature in a brutal program of eradicating the Mysteries---a task it performed so completely that today Paganism is regarded as a "dead" religion.
Although surprising to us now, to the writers of the first few centuries CE these similarities between the new Christian religion and the ancient mysteries were extremely obvious. Pagan critics of Christianity, such as the satirist Celsus, complained that this recent religion was nothing more than a pale reflection of their own ancient teachings. Early "Church Fathers," such as Justin Martyr, Tertullian, and Irenaeus, were understandably disturbed and resorted to the desperate claim that these similarities were the result of
diabolical mimicry. Using one of the most absurd arguments ever advanced, they accused the Devil of "plagiarism by anticipation," of deviously copying the true stories of Jesus before it actually happened in an attempt to mislead the gullible. These Church fathers struck us as no less devious than the Devil they hoped to incriminate.
Other Christian commentators have claimed that the myths of the Mysteries were like "pre-echos" of the literal coming of Jesus, somewhat like premonitions or prophecies. This is the more generous version of the diabolical mimicry theory, but no less ridiculous to us. There was nothing other than cultural prejudice to make us see the Jesus story as the literal culmination of its many precursors. Viewed impartially, it appeared to be just another version of the same basic story."
