Q1. Christ Our Passover Lamb

[Krissi]

I believe, but am not certain, the logic goes something like this:

1.  Passover. God saw the blood and spared the people who had sacrificed.

2. Jesus. Jesus/God's blood spared the people who believed.

3. Eucharist. The wine is the blood, or a symbol of it, which spared the people who participated in this "feast."

This may be too reductionist. The idea, perhaps, is that

Yahweh=Jesus=wine,

and the sacrificing Israelites=believing Christians=sacrificing-symbolically Christians.
