This volume includes translations of several works by St. Anastasius Sinaite, the holy father of the 7th century: “Three Words about the creation of man in the image and likeness of God”, the first three chapters of the “Guide” (the most important for understanding the main points of the theology of St. Anastasius), “A Homily on the Sixth Psalm” and “A Homily on the Holy Assembly.” All these creations of a little-known ancient church thinker in Russia are striking monuments of patristic theology and precious evidence of the enduring value of Holy Tradition.
