Fr. Cantalamessa's homily for this sunday is quite beautiful:
"All this tells us something important about the Resurrection. The latter is not only a great miracle, an argument or a proof in favor of the truth of Christ. More than that, it is a new world in which one enters with faith accompanied by wonder and joy. Christ's resurrection is the 'new creation.'"
You can check out Zenit for the whole thing. And don't miss Fr. Cantalamessa's site either.
