This practice of the Christian assembly dates from the beginnings of the apostolic age.[112] 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."[113]

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."[114]
