Pachomius the Great

Saint Pachomius (Greek:Παχώμιος, Coptic: ⲡⲁϩⲱⲙ ca. 292–348), also known as Pachome and Pakhomius (/pəˈkoʊmiəs/), is generally recognized as the founder of Christian cenobitic monasticism. Coptic churches celebrate his feast day on 9 May, and Eastern Orthodox and Roman Catholic churches mark his feast on 15 May or 28 May. In the Lutheran Church, the saint is remembered as a renewer of the church, along with his contemporary (and fellow desert saint), Anthony of Egypt on January 17.
