 We receive communion. It also helps us to realize why we want to spend this time with our Lord. We have this other prayer. We respond to the priest, to our Lord, and we say, Lord, I'm not worthy that you should enter under my roof, but only say the word and my soul shall be healed. Do you ever wonder, why are we talking about the roof of the church, the roof of the house? What are they talking about, the roof of my mouth? What are we talking about here? These words also come from the Bible. They come from the Roman centurion.
