Pope Saint John Paul II instituted Divine Mercy Sunday in 2000. But Christ’s unfathomable mercy has been available to us long before the Church officially established a day to celebrate it. Saint Paul, one of the first Christians, was eager to remind us of that:
We know from the Bible that there is a temporal connection between Passover and Easter—Jesus’ Passion takes place right after he eats the Passover meal with his disciples. But this timing is more than just a coincidence. Jesus’ Passion, death, and resurrection is actually the fulfillment of the Passover.
"O sublime humility! O humble sublimity!"
