The trouble is that our eyes cannot see the true glory of the Resurrection. It is as if the Sun has risen, not just on one day, but on the whole of History. It is a Sunrise from Eternity that cuts across the ages casting a shadow of the Cross on all human activity. It is this aspect that allows us to consider each and every Mass as part of the same, one, perfect oblation for the remission of our sins. We are looking in a direction perpendicular to the passage of Time as we know it. This truly is the Dawn from on High that has broken upon us.
We must remember that Our Lord's life is indivisible. We can never separate Bethlehem, Galilee, Jerusalem, Calvary, and the Empty tomb. Each of these are part of the sunrise, dispelling darkness and allowing us to open sleepy eyes to behold the reality that lies beyond reality summed up in that tiny phrase "The Word became Flesh and dwelt among us."
This is the true Victory over darkness. All the subterfuge of the Devil and his minions is exposed in the light of God's Sunrise from Eternity. It has nowhere to hide, and though shadows are cast, the nature of what is casting those shadows becomes utterly obvious to those who use the sunrise to see the Eternal Truth. Let those who question the nature of this light disperse in their unbelief. If they cannot believe in Eternity with some conviction but remain with their eyes firmly fixed upon the secular, then they are the ones who will miss gazing upon things that transcend the pressing problems of a fleeting age.
As we stand gazing up at the sunrise and see the Risen Lord radiating the warmth for our souls from His person, we say "This is the Day that the Lord has made! We will rejoice and be glad in it!"
