Why Sunday? It’s obvious: the Resurrection. The only event that might be more astonishing is that God chose to come in human form, and walk among us, as one of us. But no doubt, the Resurrection has eternal implications for all those invited to follow in the path of Jesus Christ:
2. The Resurrection of Jesus is the fundamental event upon which Christian faith rests (cf. 1 Cor 15:14). It is an astonishing reality, fully grasped in the light of faith, yet historically attested to by those who were privileged to see the Risen Lord. It is a wondrous event which is not only absolutely unique in human history, but which lies at the very heart of the mystery of time. In fact, “all time belongs to [Christ] and all the ages”, as the evocative liturgy of the Easter Vigil recalls in preparing the Paschal Candle.
Why an Easter every Sunday? Because …
Therefore, in commemorating the day of Christ’s Resurrection not just once a year but every Sunday, the Church seeks to indicate to every generation the true fulcrum of history, to which the mystery of the world’s origin and its final destiny leads.
Sunday is the fundamental day of Christianity, and for a number of reasons. It gives us the evangelical impulse–the reason why we have good news for everybody. There’s the fact that the Resurrection changed history, and perhaps we need a reminder of that every week. Vatican II taught that it is the primordial feast day.
It is right, therefore, to claim, in the words of a fourth century homily, that “the Lord’s Day” is “the lord of days”.(Pseudo-Eusebius of Alexandria, Sermon 16: PG 86, 416) Those who have received the grace of faith in the Risen Lord cannot fail to grasp the significance of this day of the week with the same deep emotion which led Saint Jerome to say: “Sunday is the day of the Resurrection, it is the day of Christians, it is our day”.(In Die Dominica Paschae II, 52: CCL 78, 550) For Christians, Sunday is “the fundamental feastday”,(Sacrosanctum Concilium 106) established not only to mark the succession of time but to reveal time’s deeper meaning.
Has that vital weekly reminder become a ho-hum everyday experience of leisure? A day like any other day: enslaved to work, play, and the whims of our masters in the world and in our selves?
