I’ve looked at the concept of gods dying and being resurrected before, and it really seems like there’s a tendency to ascribe more similarities to the various myths of the sort than there really are. It’s a common theme, but not all the stories work the same way. It’s been proposed that the entire story of Jesus’ death and resurrection, and sometimes even the basic outline of his life, are based on an earlier myth. There’s still a meme going around that originated sometime in the nineteenth century with an amateur Egyptologist named Gerald Massey, who insists that the Egyptian god Horus was said to have been born of a virgin, baptized in a river, led twelve disciples, crucified between two thieves, and come back to life after three days.
Now, Egyptian mythology developed a lot over the centuries, but I have yet to see any evidence outside the meme itself that ANY of these things are accurate. About the closest you can get is that Isis is said to have healed her son after he was stung by a scorpion or bitten by a snake, but it’s a real stretch to say that that counts as a resurrection.
I’ve also seen accounts of Krishna and Dionysus being crucified, but more reliable sources indicate that Krishna was killed with an arrow, while Dionysus was either transferred into Zeus’s leg after his mother died or revived after being torn apart by Titans. There’s definitely a recurring theme here, but is there necessarily any conspiracy involved? I mean, people in every society die, so being able to conquer death would be pretty much the ultimate miracle no matter where you go.
When comparing and contrasting such myths, I would say it’s important to acknowledge that not every culture or religion saw death in the same way. Some teach that life just ends, others believe in a spiritual or physical afterlife, and still others favor reincarnation or the soul being absorbed into nature. I’ve seen references to the ancient Greek dead as “shades,” but they must have some physical being if they can feel the pleasures of Elysium or the torments of Tartarus. If Orpheus had been successful in rescuing Eurydice from Hades, what form would she have taken back in the world of the living? Would she have been a ghost, regained the use of her body, or gotten a new body? The indication in Greek mythology seems to be that it would be physically possible for the dead to return to the surface, but the gods make sure it doesn’t happen, because it would mess up the established order. For that matter, can a god die at all, and if so will they stay dead? Osiris was reassembled after having his body cut to pieces, but had to remain in the underworld.
Persephone is forced to commute between Hades and the surface, but as the daughter of two of the top Olympians, I doubt she could actually die.
Baldur does straight-up die, but it’s said that he could have come back if it weren’t for Loki‘s interference, and he actually will return to life after most of the other gods bite the dust at Ragnarok.
And would Ganesh losing his head and having it replaced count as a resurrection?
Also, early Christians disagreed on the exact nature of Jesus’ resurrection, as well as whether or not he was actually God. The orthodox answer was kind of similar to that of avatars in Hinduism. The Greek and Norse gods would hang out on Earth incognito, but I don’t know of any stories of their flat-out living an entire human life from birth to death. On the other hand, Krishna didn’t have his earthly body restored after dying, but just returned to being Vishnu.
The Trinity can perhaps also be linked to the Hindu Trimurti, but many other religions have gods taking on multiple aspects.
I couldn’t say whether there was actual Indian influence on early Christianity, or vice versa for that matter. The orthodox Christian view does seem to incorporate both Jewish and pagan elements, but that doesn’t mean it directly parallels anything else. Certainly, a lot of things Christians seem to take for granted wouldn’t have really fit into a first-century Jewish mindset, at least from what I know of it. There were ideas that the Messiah could be either an Earthly king or a heavenly being, but I don’t know of one that he’d actually be God in the flesh, or that he would suffer and die for humanity, come back to life, be born of a virgin, release people from the Law of Moses (I doubt many of them would have seen that as something from which they’d WANT to be free), or fulfill a bunch of scripture that wasn’t previously regarded as messianic prophecy. For that matter, Jesus as the ultimate sacrifice is based on the Jewish notion of animal sacrifice to atone for sin, but that wasn’t the ONLY purpose of the sacrificial system. It’s strange that there are still Christians who insist the Jews of the time rejected their Messiah, when Jesus didn’t really do anything the Messiah was supposed to do. Even if there HAD been proof that he came back from the dead (and I don’t think there was), there are other scriptural accounts of people coming back to life, and they weren’t worshipped. There are also stories of people who aren’t on God’s side being able to do miraculous deeds. Perhaps that’s part of why, despite deriving from Judaism and being centered around a Jew, Christianity caught on more with gentiles. They might have seen some appealing similarities to their previous beliefs, but that doesn’t make it a direct rip-off of Horus or Osiris.
You have to turn the crank and listen to “Pop Goes the Weasel” before Jesus comes out.
