He was disciple of the hermits Barsanuphius and John the Prophet and is venerated as saint by the Eastern Orthodox Church on 13 August.
Seridus was an extreme ascetic and nearly died due to his practices before he was healed by Barsanuphius who then became his spiritual director.
Seridus' monastery functioned in the typical manner of Gazan monasticism: a coenobium that supported surrounding hermit cells.
[3] Seridus also became the only person allowed to communicate with Barsanuphius and acted as an intermediary for those who wished to receive council and spiritual direction from the hermit known as the "Old Man".
[1] Feeling his end near, Seridus ordained that the next abbot should pass to one of the monks he ranked on a list.
