I'm just finishing up a book on the effect of Judaism on Early Christianity, and the author made what might be a profound observation.
The Passover (which many people consider Communion a form of) was the only sacrifice in ancient Israel where everyone got to take the role of a priest (or at least a position in a priest's household).
In the most commonly described sacrifices, someone would either pay money for an animal to be sacrificed or bring a sacrifice to the Temple. The priest would then be given the sacrifice as a representative of God. The priest would then given part of that sacrifice to God as a tithe and eat the rest.
The Passover was different. The head of each family would bring a sacrifice into the temple courts and sacrifice it themselves and then take the sacrifice back to their household to be eaten.
I find this interesting, but I'm wondering what conclusions one could draw are valid interpretations and which are simply fancy.
