Desert Fathers
Romanos 14:12
A brother asked Ammon, 'Speak a word to me.' He said to him, 'Go and meditate like the criminals in prison. They keep asking, where is the judge, when will he come? and because they are waiting for him they dread their punishment. The monk should always be waiting for his trial, chiding his soul, saying: "Alas, how shall I stand before the judgement seat of Christ? How shall I give an account of my actions?" If you always meditate like this, you will be saved.' — The Desert Fathers, Sayings of the Early Christian Monks
Romanos 14:13
Joseph asked Poemen, 'Tell me how to become a monk.' He said, 'If you want to find rest in this life and the next, say at every moment, "Who am I?" and judge no one.' — The Desert Fathers, Sayings of the Early Christian Monks
