St. Narcissus (3rd century)
Narcissus was a bishop of Jerusalem. Late in life, after he was falsely accused of a crime, he resigned his post in order to prevent scandal and he became a desert hermit. After a complete acquittal, he returned to his see and served for several more years. He lived to the age of 116.

Reflections from the Saints

Belief in the Eucharist is a treasure we must seek by submissiveness, preserve by piety, and defend at any cost. Not to believe in the Blessed Sacrament is the greatest of misfortunes.
