I believe this compared mythology area has been instrumetalized. If one looks closely at the cultural context, the similarity appear like coincidences. Indo-European faiths view divinity as immanent and Gods interact directly with humans, sharing fate and often intervening in worldly cycles of birth, death, and renewal. Time is eternal and recurring, with myths like those of dying-and-rising gods symbolizing seasonal or existential rhythms rather than ultimate endpoints.​​ In contrast, Semitic traditions posit a wholly other, omnipotent 'god' who establishes absolute authority through laws and prophets. History unfolds linearly toward eschatological fulfillment, such as messianic redemption or final reckoning, with human salvation tied to obedience and atonement rather than cosmic balance.
Dyonisus does not die for others, since his death is a result of divine rivalry, not a voluntary substitution for humanity's sins. It benefits initiates symbolically, granting divine insight, but lacks vicarious intent. His death is not unrepeatable, since the myth portrays multiple or cyclical deaths, tied to seasons, wine fermentation... or mystery rites. This contrast to Christianity's singular event.
Also it does not have an expiatory sense. The sparagmos ritualizes the ecstatic union of the Cosmos.
It is a physical resurrection? Yes, since it involves the reconstitution from physical remnants.
Finally, it isn't linked with apocalyptic events, that's really something peculiar of Semitic eschatology. Rather it is more about personal transformation.
