Q. When, as believers, we break bread at the Lord’s Supper should we use Unleavened Bread, or normal everyday bread? I can understand using Matzos (unleavened bread) at Passover, but the rest of the year? A secondary question is:- Do we need to use Matzos even at Passover as this is a Jewish Feast under the Law?
A. Some Christian groups use matzo bread in their communion services because that’s what Jesus used when He instituted the practice. We know this because it was during a Passover Celebration where unleavened bread is specified (Exodus 12:8, 1 Cor. 11:23-26). As far as I know there’s no Biblical requirement for matzo bread at a communion service.
There is also no requirement for Christians to partake of the Passover meal. Those who do often use matzo bread to be historically accurate, and because its appearance (it’s striped and pierced, like He was) makes it part of a long list of symbolic references to the Messiah that can be found in the Passover celebration. These references illustrate the prophetic message of Passover, supporting John’s introduction of the Lord as the Lamb of God who takes away the sin of the world (John 1:29) and Paul’s reference to Jesus as our Passover Lamb (1 Cor. 5:7).
