Mark the Ascetic - On the Spiritual Law 126-130

126. He who seeks forgiveness of his sins loves humility, but if he condemns another he seals his own wickedness.
127. Do not leave unobliterated any fault, however small, for it may lead you on to greater sins.
128. If you wish to be saved, welcome words of truth, and never reject criticism uncritically.
129. Words of truth converted the 'progeny of vipers' and warned them 'to flee from the anger to come' (Matt. 3:7).
130. To accept words of truth is to accept the divine Word; for He says: 'He that receives you receives me' (Matt. 10:40).
