Dorotheus of Gaza ( Dorotheos tes Gazes; 505 – 565 or 620,) or Abba Dorotheus, was a Christian monk and abbot. Life He joined the monastery Abba Serid (or Abba Sveridus) near Gaza through the influence of elders Barsanuphius and John. Around 540 he founded his own monastery nearby and became abbot there. It was to the monks of this monastery that he addressed his instructions/teaching (, "ascetics") of which a considerable number have survived and have been compiled into Directions on Spiritual Training, originally composed in Greek and translated in medieval Syriac, Arabic, Georgian, and Church Slavonic. It is typical that at the heading of his teachings he announces that he offers his teaching "following the death of Abba John the Prophet and the complete silence of Abba Barsanuphius". It seems that as long his holy spiritual fathers lived he thought that he should live in obedience, keep silent and not give his own teaching. Only after the demise of one and the decision of the other not to speak did he decide to record his ascetic experiences, in order to edify the monks at the new monastery. He presents his teaching looking to one sole aim, the edification of those to whom it is addressed. He is not interested in elegance of expression or style. Thus, his words are uncontrived, clear and simple. A careful study of the teachings of Abba Dorotheus shows a strict logical structure in an intelligible and analytic manner. The matters are not approached in a theoretical way, but on the basis of everyday reality and on his monastic experience. He primarily links his teaching with the Holy Scripture and often introduces the subjects by starting from a biblical quote or passage, mainly from the Old Testament. Furthermore, he uses biblical citations from both the Old and New Testament throughout the development of his thought. In his practical teaching, Abba Dorotheus does not ignore the theology of the Church. In his thought, theology and the practical-ascetic life coexist. He certainly is not interested in giving some doctrinal teaching. Nevertheless, his practical teaching is saturated by the faith of the Church. Abba Dorotheus (St. Dorotheus the Hermit of Kemet) is recognized as a saint by the Eastern Orthodox Church and Roman Catholic Church and Oriental Orthodox Church with his Feast Day on June 5 in the Roman Catholic Church, June 18 (June 5 old style)
