[Evangelical]

Corn bread? Unlikely - Jews prohibit the consumption of corn, rice etc during Passover. Approved grains are wheat, rye and some others (I forget).

So you know about the Passover, you know that Christ is our unleavened bread.

So why use leavened bread when unleavened is available? Leavened bread is not a symbol of Christ, it's a symbol of a dinner roll or a bowl of soup. To be honest when I see the leavened bread on the table I'm thinking about pumpkin soup, not Christ.
