St. Poimen (or Pimen, or Poemen) the Great was born in Egypt in about 340. He and his two brothers joined themselves to a monastery in Scetis. After raids on Scetis caused the monastics to disperse, they began to assemble the Sayings of the Desert Fathers (the Apophthegmata Patrum), in which St. Poimen is the abba or poemen (“shepherd”) most often quoted.

“For many of the monks, Saint Pimen was a spiritual guide and instructor. They wrote down his answers to serve for the edification of others besides themselves. A certain monk asked, ‘If I see my brother sinning, should I conceal his fault?’ The Elder answered, ‘If we reproach the sins of brothers, then God will reproach our sins. If you see a brother sinning, do not believe your eyes. Know that your own sin is like a beam of wood, but the sin of your brother is like a splinter (Mt. 7:3-5), and then you will not enter into distress or temptation.'”

“Once, a monk from another country came to the saint to receive his guidance. He began to speak about sublime matters difficult to grasp. The saint turned away from him and was silent. They explained to the bewildered monk that the saint did not like to speak of lofty matters. Then the monk began to ask him about the struggle with passions of soul. The saint turned to him with a joyful face, ‘Now you have spoken well, and I will answer.’ For a long while he provided instruction on how one ought to struggle with the passions and conquer them.

“Saint Pimen died at age 110, about the year 450. Soon after his death, he was acknowledged as a saint pleasing to God. He was called ‘the Great’ as a sign of his great humility, uprightness, ascetic struggles, and self-denying service to God.” oca
