Because of how the gospel connects indicatives to imperatives, we can not only say: you are what you eat, but also you eat what you are. When we eat and drink Christ's body we are being knit together and strengthened. Our faith is strengthened by His bread, our hearts are gladdened by His wine.
But we are also eating what we are. We are, in Christ, bread that strengthens the faith of others. We are, in Christ, wine that gladdens the hearts of others. We are a new lump, and what is it good for? It is good to be eaten. We are new wine, and what is it good for? It certainly can’t stay in old wine skins.
So Christ's body is bread and wine to us, and also we are bread and wine as Christ's body. We celebrate all that we have in Him because He is our Passover lamb who has been sacrificed. And that celebration is not limited to one day of the week or one week of the year. That celebration extends to our lives.
Feast here on Christ in communion, and remember that you eat what you are. How will you celebrate with unleavened bread of sincerity and truth? Put off the old self which is corrupt through deceitful desires and put on the new self, created after the likeness of God in true righteousness and holiness (Ephesians 4:22-24). Do honest work so that you have something to share (Ephesians 4:28), speak for the building up of others that gives grace to those who hear (Ephesians 4:29). Walk in love as Christ loved us and gave Himself up as a fragrant offering (Ephesians 5:2). You are that fragrant offering in communion with Him.
