Martyrs and Catacombs

Also known as Sayings of the Desert Fathers or Apophthegmata Patrum, are a collection of moral and spiritual maxims from early Christian monks (3rd to 5th centuries) emphasizing humility, asceticism, discernment, and constant prayer. Key themes include taking responsibility for one's own sins, the importance of humility to overcome temptations, the need for inner stillness and struggle, and striving to put God's will before one's own. During this period several churches record martyrdom deeds of various saints to commemorate at different times of years, and their relics are preserved at specific locations.
