The little that is known about the life of Anastasius of Sinai is gathered from his own works. In Antiquity, he was often confused with the presbyter and writer Anastasius I of Antioch (559 – 598), and the authorship of various works attributed to Anastasius of Sinai is still vigorously disputed. A canon has been tentatively accepted by modern scholars, but even among these Anastasian works there are spurious sections.
His writings concern questions and answers about issues of Christian dogma, ritual, and lifestyle (catechism).
Sermons; and exegesis. He was fond of tracing the etymologies of key Christian terms.
He was erudite in the Bible and early Patristic literature. And he had a pervasive interest in the nature of God and man, especially in the Person of Christ (Christology).
