Because it follows the Exodus story, the Lectionary tells us about Passover just after Labor Day. This seems strange, because this Jewish feast always falls in early spring, often near our Easter. What God tells Moses to do here is a ritual. Many of us flee from ritual. When people do a passover meal, they sometimes call it a “Seder,” which means an order of service or a ritual. God speaks through Moses, saying, do this and you shall live. God is serious about this and Moses must have been persuasive. How else would he get people to splash blood upon the door posts of their house?
