The 14th century was the time of the Palamite controversy in the Eastern Church. St Gregory Palamas (1296–1359), a monk of Mount Athos, was a practitioner of the method of prayer called hesychasm (hesychia means ‘silence’). This method of prayer is centered in the continuous repetition of the name of Jesus, usually in the form of the Jesus Prayer: “Lord Jesus Christ, Son of God, have mercy on me, a sinner.” And a rigorous bodily discipline—emphasizing certain sitting postures and breathing techniques—is employed in order to help unite the mind and heart in God. Through the use of this method of prayer, the hesychast monks claimed to experience genuine communion with God, including sometimes a vision of the Uncreated Light of Divinity such as that seen by Moses on Mount Sinai, and by the Apostles Peter, James, and John at the Transfiguration of Christ on Mount Tabor.

In 1330 Barlaam the Calabrian, an Italo-Greek monk raised in an Orthodox family in southern Italy but educated in the Scholastic spirit prevailing in Western Europe at that time, came to Constantinople and accepted a chair in philosophy at the University of Constantinople. Barlaam, along with a number of other Byzantine humanists who were highly influenced by Western philosophical and theological ideas, ridiculed the practice of hesychastic prayer. They denied the possibility for human beings to be in direct, genuine communion with God.

Essence and Energies

In 1337 Gregory Palamas confronted Barlaam’s position and began his defense of hesychasm and the various contemplative practices of the Athonite monks. He confirmed the Orthodox doctrine that man can truly know God and can enter into living communion and relationship with Him through Christ and the Holy Spirit in the Church. He explained that the Essence (or Super-Essence) of God is utterly unknowable and incomprehensible, while at the same time, the actions, operations, or Energies of God, which are also uncreated and fully divine (such as the Divine Light), are communicated to people by divine grace and are open to human knowledge and experience. This is what is meant when Christians are said to become “partakers of the divine nature” (2 Pet 1.4).

A local council held in 1341 in Constantinople upheld Gregory’s teaching. Amid ten more years of political turmoil and theological controversy, local councils held in 1347 and in 1351 reaffirmed Gregory’s position as that of the Bible and the whole Tradition of the Orthodox Church. From that time this crucial theological distinction between the divine Super-Essence and the divine Energies became an official part of the doctrine of the Orthodox Church.

This Saint gave himself over to the ascetical life from his early youth. Experienced both in the solitary life of the hermit and in the communal life of cenobitic monasticism, he was appointed Abbot of the Monastery at Mount Sinai and wrote a book containing thirty homilies on virtue. Each homily deals with one virtue, and progressing from those that deal with holy and righteous activity (praxis) unto those that deal with divine vision (theoria), they raise a man up as though by means of steps unto the height of Heaven. For this cause his work is called "The Ladder of Divine Ascent." The day he was made Abbot of Sinai, the Prophet Moses was seen giving commands to those who served at table. Saint John reposed in 603, at eighty years of age. See also the Fourth Sunday of the Fast.

When Mary was only twelve years old, she left her parents and departed to Alexandria, where she lived a depraved life for seventeen years. Then, moved by curiosity, she went with many pilgrims to Jerusalem, that she might see the Exaltation of the venerable Cross. Even in the Holy City she gave herself over to every kind of licentiousness and drew many into the depth of perdition. Desiring to go into the church on the day of the Exaltation of the Cross, time and again she perceived a certain invisible power preventing her entrance, whereas the multitude of people about her entered unhindered. Therefore, wounded in heart by this, she decided to change her way of life and reconcile herself to God by means of repentance. Invoking our Lady the Theotokos as her protectress, she asked her to open the way for her to worship the Cross, and vowed that she would renounce the world. And thus, returning once again to the church, she entered easily. When she had worshipped the precious Wood, she departed that same day from Jerusalem and passed over the Jordan. She went into the inner wilderness and for forty-seven years lived a most harsh manner of life, surpassing human strength; alone, she prayed to God alone. Toward the end of her life, she met a certain hermit named Zosimas, and she related to him her life from the beginning. She requested of him to bring her the immaculate Mysteries that she might partake of them. According to her request, he did this the following year on Holy and Great Thursday. One year after this, Zosimas again went thither and found her dead, laid upon the ground, and letters written in the sand near her which said: "Abba Zosimas, bury here the body of wretched Mary. I died on the very day I partook of the immaculate Mysteries. Pray for me." Her death is reckoned by some to have taken place in 378, by some, in 437, and by others, in 522. She is commemorated also on the Fifth Sunday of Great Lent. Her life was recorded by Saint Sophronius of Jerusalem.
