After Christianity gained prominence, church leaders developed the practice of merging Christian holy days and symbols with those of pagan holidays, in order to weaken people's reliance on paganism by supplanting it with Christian ideology. In time, wherever Christian worship of Jesus and Pagan worship were active in the same geographical area in ancient times, Christians:
"... used to celebrate the death and resurrection of Jesus on the same date; and pagans and Christians used to quarrel bitterly about which of their gods was the true prototype and which the imitation."
But church leaders clearly knew which worship was older. We now know that the oldest death and resurrection legend was first associated with Ausar of Kemet. Ausar was part of a trinity that consisted of him, the father, Auset, the mother, and their son, Heru (who was the second person in this trinity). As time elapsed, in the Hellenistic world, Ausar was dropped or deemphasized, and the sacred family was reduced to Auset and Heru, or Isis and Horus, their respective Greek names. In the Roman world, these two were worshiped throughout the empire, identified as the (Black) Madonna and child. Church leaders were able to successfully merge/graft their story of Jesus onto the story of Heru, eventually negating or replacing the latter altogether. Ancient Christians developed two alternative explanation for the similarities between their savior and other savior gods of the ancient world: first, they claimed that Satan had created counterfeit deities in advance of the coming of Christ in order to confuse humanity, and second, they regard Jesus' death and resurrection account as being true, historical, while others they argued were simply mythological.
