How can it be another name for the same person but two different entities? That doesn't make any sense.

The whole legend is that the archangel Michael went to Earth as a human and died for human sin then got crucified and went back to Heaven after being resurrected by God. That's what the whole virgin mary is based on, she got pregnant because God planted his angel inside of her so Michael aka Jesus could be born as a perfect moral. That's why Jesus had the power to resurrect people and such because the legend goes that he was originally an angel. They're the same person just in different forms.

To put it in DxD terms that's like saying Issei isn't Issei anymore because he was resurrected using Great Red's Flesh. It's still the same person just a different state of being/body.
