Yes good question. But I’d say we could look at history/mythology for an answer to that. There have always been savior figures. They spring up in every mythology known to man. It’s our rather monotheistic world view that makes us think there can only be ONE.
Even in the Bible, there are arguably several savior-like figures, who all predate Christ (e.g. Noah, Joseph, Moses, Joshua, Esther, and David).
But..you’ve seen the Matrix, yeah? Neo in the “One” but he’s also one of many. He’s part of an equation that played itself out over and over. He’s not the first, but he is the last. That’s Emma. She might not be the first Savior, because Savior’s rise up in times of cosmological crises, but she is the Last.
Yeah. If Emma is comparable to Christ, she is the one who will “overcome death, once and for all.”
