Reading from the Synaxarion:

Sabbas the Sanctified

This Saint was born in 439 in Moutalaska, a small village of Cappadocia. He entered the arena of the monastic life from childhood and was under that master trainer of monastics, Euthymius, the Great, the teacher of the desert. He became the spiritual Father of many monks and an instructor for the monasteries in Palestine, and was appointed leader (archimandrite) of the desert-dwellers of Palestine by the Patriarch of Jerusalem. In his old age he went to Constantinople, to the Emperors Anastasius and Saint Justinian the Great, in behalf of the Orthodox Faith and the dogmas of the Council of Chalcedon. Having lived ninety-four years, he reposed in 533. The Typicon for the ecclesiastical services had its beginning in the monastery established by this righteous one.
