My own view is that the Easter story is one of many stories of dying and resurrecting deities. In these stories, the hero dies, descends to the underworld, and returns to the mortal world bringing some blessing or new knowledge. Persephone is taken to the Underworld by force, but returns every six months; Gilgamesh goes to rescue his friend Enkidu from death; Orpheus goes to rescue Eurydice. Jesus goes there to rescue the souls of those trapped in Gehenna (this is referenced in the only letter of the Apostle Peter). In Christus Victor theology, which is prevalent among the Eastern Orthodox churches, Jesus “tramples down death by death” and because he is God, cannot be contained by death, and so transcends it. He then returns transformed into a being who can manifest as he chooses — by the Sea of Galilee, or on the road to Emmaus. The mythical journey undergone by all these heroes and heroines is a descent into death and the underworld, returning transformed into something greater, and bringing back a gift for humanity. The hymn Now the green blade rises references this mythological and transformational aspect of the Easter story.
The spiritual journey involves the same transformation — the death of the ego, the descent into the dark night of the soul, and the resurrection as the True Self. In Orthodox Christian theology, this transformation is called theosis, literally deification, making us divine. It’s not too hard to see an analogy with the Buddhist concept of enlightenment. As James Martineau, the 19th century Unitarian theologian, said, “The Incarnation is true, not of Christ exclusively, but of Man universally, and God everlastingly. Humanity is the susceptible organ of the Divine, and he bends into it to dwell there.”
In Orthodox churches, Easter is celebrated as a unified event, and is regarded as being in the present, the eternal Now. So on Easter Sunday, people greet each other with “Christos Anesti” (Christ is risen) - because he is risen in their hearts and in the church which is his mystical body (and they presumably believe it literally as well).
In the Eleusinian Mysteries, people witnessed the unfolding drama of the story of Persephone’s descent into the Underworld, and underwent a profound transformation or initiation as a result.
You can enjoy Easter on a mythical and mystical level. There’s no need to take it literally to enjoy the unfolding drama of the Mystery. We can witness the many stories of death and resurrection and experience transformation ourselves, like participants in a mystery tradition.
