Yesterday, by the way, was also the Feast of St. Alypius, who was the life long friend of St. Augustine of Hippo, who became the bishop of Augustine’s home town. Here is his entry in the Martyrologium Romanum:
5. Commemoratio sancti Alypii, episcopi Thagastensis in Numidia, qui sancti Augustini olim discipulus, postea in conversione socius, in munere pastorali collega et in certaminibus adversus haereticos commilito strenuus ac demum in caelesti gloria consors fuit. … The commemoration of Saint Alypius, bishop of Thagaste in Numidia, who having once been the student of Saint Augustine, later was his companion in conversion, his colleague in pastoral care and a fellow soldier, strenuous in their battles against heretics, and later his fellow participant in heavenly glory.
