One day Paschal heard the bells of a convent announce the approaching consecration at Mass. Such an ardent longing for God overcame him that, prompted by yearning and love, he involuntarily cried out: "O God, most worthy of all adoration, please let me see You!" Hardly had he uttered the prayer when a glowing star appeared in the sky. As he watched, the heavens opened; the star disappeared and was replaced by a chalice with the Host, flanked by two adoring angels. Christian art has selected this vision to show his chief virtue, viz., love for the most holy Eucharist.
