We use this for communion at Hope Chapel. Today, Pastor Jeff described it this way.
We share bread together to remember Christ's sacrifice for us on the cross. It's broken and we each take a piece.
The bread is unleavened (without yeast or any leavening agent) reminding us that "but we have one who has been tempted in every way, just as we are—yet was without sin." (Hebrews 4:15)
The bread has strips across it to remind us that "and with his stripes we are healed." (Isaiah 53:5)
The bread has holes in it to remind us that "but he was pierced for our transgressions." (Isaiah 53:5)
I've heard this before, but it's a good reminder to remember what Christ did for ME and to share this good news with others. And to continue to fellowship and encourage those in the family of God "to love and good deeds...and all the more as you see the day drawing near." (Hebrews 10:24-25)
