Note 1 at Lu 22:19: The bread of communion symbolizes the body of Jesus that was broken for us through His sufferings. He not only died for us on the cross, but He also bore thirty-nine stripes on His back by which we were healed (Isa 53:5, Mt 8:16-17, and 1Pe 2:24). Partaking of communion should remind us of the emotional and physical salvation that Jesus provided for us.

Note 2 at Lu 22:19: Communion reminds us of the substitutionary work of Christ (see note 2 at Mr 14:22), and it also is a profession on our part that we have become partakers of Christ and draw our life from His death and resurrection (Joh 6:53 and 1Co 11:26). This second purpose was the reason that Paul said eating and drinking of the Lord's Supper unworthily could bring damnation. A person who takes communion without being cleansed by the blood of Jesus is professing a lie.
