SUNDAY - (In Russian it is called the Resurrection Day). First day of the week consecrated in a special way to Christian worship. It is observed from Apostolic times. Sunday, the Lord’s Day, is a special day consecrated to the service and worship of God. It is “the day the Lord has made” (Ps. 117 (118):24). Its nature is holy and joyful. Sunday is the day on which we believe God acted decisively to liberate the world from the tyranny of sin, death, and corruption through the Holy Resurrection of Jesus. The Church precepts forbid manual labor on Sunday, and command attendance at Divine Liturgy.
Sunday is more than just the first day of the week. In our faith we see how it is the ultimate day of new beginnings: “It is a Pascha which returns week by week, celebrating Christ's victory over sin and death, the fulfillment in him of the first creation and the dawn of "the new creation" (cf. 2 Cor 5:17). It is the day which recalls in grateful adoration the world's first day and looks forward in active hope to "the last day", when Christ will come in glory (cf. Acts 1:11; 1 Th 4:13-17) and all things will be made new (cf. Rev 21:5. The Lord’s Day, 1).
