When the most pure Mother and Ever-Virgin Mary's forty days of purification had been fulfilled, she took her first-born Son to Jerusalem on this, the fortieth day after His birth, that she might present Him in the temple according to the Law of Moses, which teaches that every first-born male child be dedicated to God, and also that she might offer the sacrifice of a pair of turtle-doves or two young pigeons, as required by the Law (Luke 2:22-24; Exod. 13:2; Lev. 12:6-8). On this same day, a just and devout man, the greatly aged Symeon, was also present in the temple, being guided by the Holy Spirit. For a long time, this man had been awaiting the salvation of God, and he had been informed by divine revelation that he would not die until he beheld the Lord's Christ. Thus, when he beheld Him at that time and took Him up into his aged arms, he gave glory to God, singing: "Now lettest Thou Thy servant depart in peace, O Master. . ." And he confessed that he would close his eyes joyfully, since he had seen the Light of revelation for the nations and the Glory of Israel (Luke 2:25-32). From ancient times, the Holy Church has retained this tradition of the churching of the mother and new-born child on the fortieth day and of the reading of prayers of purification.

Saint Isidore of Pelusium lived during the fourth and fifth centuries. He was a native of Alexandria, and was raised among pious Christians. He was a relative of Theophilus, Archbishop of Alexandria, and of his successor, Saint Cyril. While still a youth he quit the world and withdrew to Egypt to Mount Pelusium.

Saint Isidore’s spiritual wisdom and strict asceticism, combined with his broad learning and innate knowledge of the human soul, enabled him to win the respect and love of his fellow monks in a short time. They chose him as their head and had him ordained a priest.

Following the example of Saint John Chrysostom, whom he had managed to see and hear during a trip to Constantinople, Saint Isidore devoted himself primarily to Christian preaching, that “practical wisdom” which, in his own words, is both “the foundation of the edifice and the edifice itself”, while logic is “its embellishment, and contemplation its crown”.

He was a teacher and a willingly provided counsel for anyone who turned to him for spiritual encouragement, whether it was a simple man, a dignitary, a bishop, the Patriarch of Alexandria, or even the emperor. He left behind about 10,000 letters, of which 2,090 have survived. A large portion of these letters reveal profound theological thought and contain morally edifying interpretations of Holy Scripture. Saint Photius calls Isidore a model of priestly and ascetical life.

Saint Isidore’s love for Saint John Chrysostom resulted in his support of Saint John when he was persecuted by the empress Eudoxia and Archbishop Theophilus. After the death of Saint John, Saint Isidore persuaded Theophilus’ successor Saint Cyril to inscribe the name of Saint John Chrysostom into the Church diptychs as a confessor. Through the initiative of Saint Isidore the Third Ecumenical Council was convened at Ephesus, at which the false teaching of Nestorius concerning the person of Jesus Christ was condemned.

Saint Isidore lived into old age and died around the year 436. The Church historian Evagrius writes of Saint Isidore, “his life seemed to everyone the life of an angel upon the earth.” Another historian, Nikēphóros Callistus, praises Saint Isidore thus: “He was a vital and inspired pillar of monastic rules and divine vision, and as such he presented a very lofty image of most fervent example and spiritual teaching.”
