Originally Answered: I hear the Horus, Mithra, Jesus topic/debate was debunked, please explain?
The entire: "Christianity is plagiarized from pagan religions" myth was debunked by the 1920s. First of all you need to get a copy of Lee Strobel's book: The case For the Real Jesus. In which he clearly shows you, through experts, why each of the points you talk about Horace Mithra are not parallels to Christianity. First of all, those very poor scholars that tried to make this claim had to first Christianize the myth, to try and make it conform. Now it's not possible to give you complete answers in the limited space available but let me give you a little bit from the book. T.N.D. Mettinger - a senior Swedish scholar, professor at Lund University, and member of the Royal Academy of letters, history, and the antiquities of Stockholm--- wrote one of the most recent academic treatments of dying and rising gods in antiquity. He admits in his book: The Riddles of Resurrection,: "that the consensus among modern scholars -nearly universal- is that there are no dying and rising God superseded Christianity. They all postdated the first century. ( came AFTER) Obviously the timing is critical: Christianity could not about the idea of the resurrection if myths about dying and rising gods weren't even circulating when Christianity was birthed in the first century A.D." (quoted from Strobel's book) while Mettinger takes exception to the nearly universal scholarly conviction and takes a decidedly minority position and claim that there are at least three possible and maybe as many as five possible dying and rising gods that predate Christianity: the question is this: are there any actual parallels between these myths and Jesus' resurrection? Mettinger, after combing through all of these accounts and critically analyzing them adds that none of these serve as parallels to Jesus... none of them. It's important to remember that Jesus' resurrection is a historical fact that can be proven from the witnesses and testimonies not only of the Bible but of extra biblical sources. And all of these are considered mythical not even believed as literal by those who followed that religion. Mettinger caps his study with this stunning statement: "there is, as far as I am aware, no prima facie evidence that the death and resurrection of Jesus Christ is a mythological construct, drawing on the myths and rights of the dying and rising gods of the surrounding world." In short, this leading scholar's analysis is a sharp rebuke to popular level authors and Internet bloggers who make a grand claim about the pagan origins of Jesus' returned from the dead. Ultimately, he affirms, "the death and resurrection of Jesus retained its unique character in the history of religions."
The religious belief of Mithra was: Mithras sprang Wholey formed from a rock, naked, with a hat and holding a dagger or torch or globe. This in no way reflects death and resurrection. And I think you're thinking of Osiris not Horus when you talk about death and resurrection. Osiris's body was cut into 14 pieces and then reassembled minus one part by his sister: Isis. He was then raised, not in life, he is the king of the underworld. Whether this can be called a [bodily] resurrection is questionable especially since according to Plutarch it was the pious desire of devotees to be buried in the same ground were according to local traditions the body of Osiris was still lying." End of quotes from Lee Strobel's book. You'll find this book to give you satisfactory answers and explanations as to why this entire belief was laid to rest in 1920 but has been resurrected by the same liberal left, radical fringe, minority and Internet quasi-scholars today.
