The Remembrance is the name we give to the 'Breaking of Bread' referred to in Acts 2:42. It's often known as communion. We gather to remember Jesus, and praise & worship God for his salvation The Remembrance was instituted by Jesus Christ (Luke 22:19) and he commanded his followers to gather and remember him – we do this every Sunday.
WHY BREAD AND WINE?
We know that when Jesus observed the Jewish Passover, he referred to the loaf of bread as his body and the wine as his blood (Luke 22:19-20). But what did he mean by this? Was the bread then his actual body as the Roman Catholic church teaches? We don't believe so.
When the Jesus said "I am the door" (John 10:7), he was using this mental picture to explain to his audience that he was the way that men enter into the possessing eternal life; in this image, he is "the door". The loaf of bread, likewise, is a symbol or mental picture of his body. When something is broken it is wholly given, and in the breaking of the loaf there is clear instruction that he gave himself wholly at Calvary.
When he took the cup of wine and he had given thanks to God for it, he gave it to the disciples saying that is was his blood (Mark 14:24). His chosen twelve disciples all drank it. The wine being poured out symbolises the blood of Christ being shed at the cross of Calvary. It was by this act that the New Covenant has been given effect, giving everyone the opportunity of eternal life.
