The Christian’s Memorial Day is celebrated in the partaking of the Lord’s Supper. We cannot remember Him if we do not know Him. The question is, “Do we know Him?”
Luke 22:19-20 (ESV): And he took bread, and when he had given thanks, he broke it and gave it to them, saying, “This is my body, which is given for you. Do this in remembrance of me.” And likewise the cup after they had eaten, saying, “This cup that is poured out for you is the new covenant in my blood.
