“I assure you: Anyone who believes has eternal life. I am the bread of life. Your fathers ate the manna in the wilderness, and they died. This is the bread that comes down from heaven so that anyone may eat of it and not die. I am the living bread that came down from heaven. If anyone eats of this bread he will live forever. The bread that I will give for the life of the world is My flesh.”
At that, the Jews argued among themselves, “How can this man give us His flesh to eat?”
So Jesus said to them, “I assure you: Unless you eat the flesh of the Son of Man and drink His blood, you do not have life in yourselves. Anyone who eats My flesh and drinks My blood has eternal life, and I will raise him up on the last day, because My flesh is real food and My blood is real drink. The one who eats My flesh and drinks My blood lives in Me, and I in him. Just as the living Father sent Me and I live because of the Father, so the one who feeds on Me will live because of Me. This is the bread that came down from heaven; it is not like the manna your fathers ate—and they died. The one who eats this bread will live forever.”
(John 6:47-58 Holman Christian Standard Bible ®©)
If you want Life, you are qualified to partake of the body and the blood of Jesus. Everyone is welcome, or Jesus would not have served the bread and the wine to Judas and Peter. Even unbelievers are invited, or I would not have been born again while eating His body and drinking His blood.
You are also qualified to serve the body and the blood at any meal you want to bring Life to. Paul wrote to the Corinthian believers that they were making a serious mistake by not discerning the body of Jesus in each other, so receive Him in the bread, the wine/juice, and the rest of the people who are with you.
