We have seen how former adherents of the ancient customs have since attained to a new hope; so that they have given up keeping the sabbath, and now order their lives by the Lord’s Day instead, the day when life first dawned for us, thanks to Him and His death.
Saint Ignatius to the Magnesians
1. The Lord’s Day — as Sunday was called from Apostolic times(1) — has always been accorded special attention in the history of the Church because of its close connection with the very core of the Christian mystery. In fact, in the weekly reckoning of time Sunday recalls the day of Christ’s Resurrection. It is Easter which returns week by week, celebrating Christ’s victory over sin and death, the fulfilment 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).
DIES DOMINI–Saint John Paul II
On the 7th day God rest. I know a friend of mine probably has an answer, but why did God need a day of rest? He is God after all. And if our day of rest is Sunday, why is it the first day on the calendar? Different cultures and religions have it different though.
I know the Romans and religions have a lot to do with it. And does it really matter?
