For the East it has had the same importance as the similar writings of Jerome, Sulpicius Severus and Cassian for the West.
C. Creed of Antioch quoted by Cassian.
Many disciples put themselves under his guidance; but his influence must have been limited to south Palestine, for there is no mention of him in Palladius or Cassian.
His chief work was against Cassian's Collatio, his De gratia dei ut libero arbitrio (432).
He also induced Pope Celestine to publish an Epistola ad episcopos Gallorum against Cassian.
