Jesus said to them, “Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise him on the last day. For my flesh is true food, and my blood is true drink. Whoever eats my flesh and drinks my blood remains in me and I in him. Just as the living Father sent me and I have life because of the Father, so also the one who feeds on me will have life because of me. This is the bread that came down from heaven. Unlike your ancestors who ate and still died, whoever eats this bread will live forever.”So what do you do when the bread that is broken and shared as Jesus' flesh can hurt you? When your low-gluten host is brought and distributed separately and is no longer part of the bread of the community?
You pray a lot. You feel sad. You learn that you will never know what part of the Cross you will be called upon to bear next in this life.
I know it's still the Eucharist, but now it's just a lot more complicated.
