Liturgically, each day in the octave of Easter is Easter all over again. While the world around us quickly forgets, the Church keeps on celebrating the Lord's resurrection.
In today's reading from Acts, Peter tells the crowd, "Repent...and be converted, that your sins may be wiped away." And Jesus says in the Gospel that "Thus it is written that the Christ would suffer and rise from the dead on the third day, and that repentance for the forgiveness of sins would be preached in his name."
This coming Sunday is divine mercy Sunday. We celebrate the resurrection because it means our sins are forgiven, wiped away, when we repent of them. Scripture is so clear on this. How could we doubt it?
