Greg Peters draws on Augustine, Cassian, and Pseudo-Dionysius to show that, although “monasticism is associated historically with celibacy and other forms of asceticism (such as poverty, stability, and unwavering obedience), single-mindedness is another consistent element of monasticism, and the one that seems to be more essential in the earliest tradition . . . . Thus, to be a monk is to be one, not divided; to be unified in one’s goal of coming into union with God. Though many believers live in a multitudinous manner, a μοναχός will set herself apart by living simply and singly. A monk is single-minded.”
