Writings
Mark's surviving works are practical treatises on the spiritual life as it is to be led by monks, rather than works of dogmatic theology. Among the titles ascribed to him are discourses on the spiritual law, on those who think they are made righteous by works, on repentance, on baptism, and a letter addressed to a certain Nicholas on refraining from anger and lust. A treatise against the Nestorians is also attributed to him.
Several of his treatises were incorporated into the Philokalia, and his writings were praised by later authorities, including Patriarch Photius the Great. His works circulated widely: originally composed in Greek, a number were subsequently translated into Syriac and Arabic. Modern editions and English translations exist, but devotional and translated texts remain under their translators' rights and are not reproduced here.
