1Cor 11, 17-22 When you meet there are divisions

(1Cor 11, 17-22) When you meet there are divisions

[17] In giving this instruction, I do not praise the fact that your meetings are doing more harm than good. [18] First of all, I hear that when you meet as a church there are divisions among you, and to a degree I believe it; [19] there have to be factions among you in order that (also) those who are approved among you may become known. [20] When you meet in one place, then, it is not to eat the Lord's supper, [21] for in eating, each one goes ahead with his own supper, and one goes hungry while another gets drunk. [22] Do you not have houses in which you can eat and drink? Or do you show contempt for the church of God and make those who have nothing feel ashamed? What can I say to you? Shall I praise you? In this matter I do not praise you.

(CCC 2177) The Sunday celebration of the Lord's Day and his Eucharist is at the heart of the Church's life. "Sunday is the day on which the paschal mystery is celebrated in light of the apostolic tradition and is to be observed as the foremost holy day of obligation in the universal Church" (CIC, can. 1246 § 1). "Also to be observed are the day of the Nativity of Our Lord Jesus Christ, the Epiphany, the Ascension of Christ, the feast of the Body and Blood of Christi, the feast of Mary the Mother of God, her Immaculate Conception, her Assumption, the feast of Saint Joseph, the feast of the Apostles Saints Peter and Paul, and the feast of All Saints" (CIC, can. 1246 § 2: "The conference of bishops can abolish certain holy days of obligation or transfer them to a Sunday with prior approval of the Apostolic See"). (CCC 2178) This practice of the Christian assembly dates from the beginnings of the apostolic age (Cf. Acts 2:42-46; 1 Cor 11:17). The Letter to the Hebrews reminds the faithful "not to neglect to meet together, as is the habit of some, but to encourage one another" (Heb 10:25). Tradition preserves the memory of an ever-timely exhortation: Come to Church early, approach the Lord, and confess your sins, repent in prayer.... Be present at the sacred and divine liturgy, conclude its prayer and do not leave before the dismissal.... We have often said: "This day is given to you for prayer and rest. This is the day that the Lord has made, let us rejoice and be glad in it" (Sermo de die dominica 2 et 6: PG 86/1, 416C and 421C). (CCC 2176) The celebration of Sunday observes the moral commandment inscribed by nature in the human heart to render to God an outward, visible, public, and regular worship "as a sign of his universal beneficence to all" (St. Thomas Aquinas, STh II-II 122, 4). Sunday worship fulfills the moral command of the Old Covenant, taking up its rhythm and spirit in the weekly celebration of the Creator and Redeemer of his people.
