I gotta have my orange juice.

The unity of the church is important to how we worship. Because we are one body-loaf (1 Corinthians 10:17) we are to partake of the Lord’s supper together and to show deference to one another (1 Corinthians 11:17ff). Otherwise we eat and drink judgment on ourselves. To refuse to eat with one another is to fail to walk in step with the truth of the gospel:

But when Cephas came to Antioch, I opposed him to his face, because he stood condemned. For before certain men came from James, he was eating with the Gentiles; but when they came he drew back and separated himself, fearing the circumcision party. And the rest of the Jews acted hypocritically along with him, so that even Barnabas was led astray by their hypocrisy. But when I saw that their conduct was not in step with the truth of the gospel, I said to Cephas before them all, “If you, though a Jew, live like a Gentile and not like a Jew, how can you force the Gentiles to live like Jews?” (Galatians 2:11-14 ESV)

But the unity of the church extends across the world; the sun does not set on the kingdom of Jesus. There is one body:

There is one body and one Spirit—just as you were called to the one hope that belongs to your call—one Lord, one faith, one baptism, one God and Father of all, who is over all and through all and in all. (Ephesians 4:4-6 ESV)

And we all gather to worship at one mountain, at the heavenly Jerusalem:

For you have not come to what may be touched, a blazing fire and darkness and gloom and a tempest and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them. For they could not endure the order that was given, “If even a beast touches the mountain, it shall be stoned.” Indeed, so terrifying was the sight that Moses said, “I tremble with fear.” But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel. (Hebrews 12:18-24 ESV)

Thus, weekly communion: because each week brothers and sisters gathered at the same table around the world are feasting with Jesus. As far as it lies within our power, for the sake of gospel unity we may not withhold the feast from some or withdraw from one another.
