The papal preacher Fr Raniero Cantalamessa had this reflection in his sermon on good Friday
There exists now, within the Trinity and in the world, a human heart that beats not just metaphorically but physically. If Christ, in fact, has been raised from the dead, then his heart has also been raised from the dead; it is alive like the rest of his body, in a different dimension than before, a real dimension, even if it is mystical. If the Lamb is alive in heaven, “slain, but standing,” then his heart shares in that same state; it is a heart that is pierced but living—eternally pierced, precisely because he lives eternally.
There has been a phrase created to describe the depths of evil that can accumulate in the heart of humanity: “the heart of darkness.” After the sacrifice of Christ, more intense than the heart of darkness, a heart of light beats in the world. Christ, in fact, in ascending into heaven, did not abandon the earth, just as he did not abandon the Trinity in becoming incarnate.
