Honouring the friends of God with much reverence, the Prophet-King David says, "But to me, exceedingly honourable are Thy friends, O Lord" (Ps. 138:16). And the divine Apostle, recounting the achievements of the Saints, and setting forth their memorial as an example that we might turn away from earthly things and from sin, and emulate their patience and courage in the struggles for virtue, says, "Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every burden, and the sin which doth so easily beset us, and let us run with patience the race that is set before us" (Heb. 12:1).

This commemoration began as the Sunday (Synaxis) of All Martyrs; to them were added all the ranks of Saints who bore witness (the meaning of "Martyr" in Greek) to Christ in manifold ways, even if occasion did not require the shedding of their blood.

Therefore, guided by the teaching of the Divine Scriptures and Apostolic Tradition, we the pious honour all the Saints, the friends of God, for they are keepers of God's commandments, shining examples of virtue, and benefactors of mankind. Of course, we honour the known Saints especially on their own day of the year, as is evident in the Menologion. But since many Saints are unknown, and their number has increased with time, and will continue to increase until the end of time, the Church has appointed that once a year a common commemoration be made of all the Saints. This is the feast that we celebrate today. It is the harvest of the coming of the Holy Spirit into the world; it is the "much fruit" brought forth by that "Grain of wheat that fell into the earth and died" (John 12:24); it is the glorification of the Saints as "the foundation of the Church, the perfection of the Gospel, they who fulfilled in deed the sayings of the Saviour" (Sunday of All Saints, Doxasticon of Vespers).

In this celebration, then, we reverently honour and call blessed all the Righteous, the Prophets, Apostles, Martyrs, Confessors, Shepherds, Teachers, and Holy Monastics, both men and women alike, known and unknown, who have been added to the choirs of the Saints and shall be added, from the time of Adam until the end of the world, who have been perfected in piety and have glorified God by their holy lives. All these, as well as the orders of the Angels, and especially our most holy Lady and Queen, the Ever-virgin Theotokos Mary, do we honour today, setting their life before us as an example of virtue, and entreating them to intercede in our behalf with God, Whose grace and boundless mercy be with us all. Amen.

This great and renowned sovereign of the Christians was the son of Constantius Chlorus (the ruler of the westernmost parts of the Roman empire), and of the blessed Helen. He was born in 272, in (according to some authorities) Naissus of Dardania, a city on the Hellespont. In 306, when his father died, he was proclaimed successor to his throne. In 312, on learning that Maxentius and Maximinus had joined forces against him, he marched into Italy, where, while at the head of his troops, he saw in the sky after midday, beneath the sun, a radiant pillar in the form of a cross with the words: "By this shalt thou conquer." The following night, our Lord Jesus Christ appeared to him in a dream and declared to him the power of the Cross and its significance. When he arose in the morning, he immediately ordered that a labarum be made (which is a banner or standard of victory over the enemy) in the form of a cross, and he inscribed on it the Name of Jesus Christ. On the 28th Of October, he attacked and mightily conquered Maxentius, who drowned in the Tiber River while fleeing. The following day, Constantine entered Rome in triumph and was proclaimed Emperor of the West by the Senate, while Licinius, his brother-in-law, ruled in the East. But out of malice, Licinius later persecuted the Christians. Constantine fought him once and again, and utterly destroyed him in 324, and in this manner he became monarch over the West and the East. Under him and because of him all the persecutions against the Church ceased. Christianity triumphed and idolatry was overthrown. In 325 he gathered the First Ecumenical Council in Nicaea, which he himself personally addressed. In 324, in the ancient city of Byzantium, he laid the foundations of the new capital of his realm, and solemnly inaugurated it on May 11, 330, naming it after himself, Constantinople. Since the throne of the imperial rule was transferred thither from Rome, it was named New Rome, the inhabitants of its domain were called Romans, and it was considered the continuation of the Roman Empire. Falling ill near Nicomedia, he requested to receive divine Baptism, according to Eusebius (The Life of Constantine. Book IV, 61-62), and also according to Socrates and Sozomen; and when he had been deemed worthy of the Holy Mysteries, he reposed in 337, on May 21 or 22, the day of Pentecost, having lived sixty-five years, of which he ruled for thirty-one years. His remains were transferred to Constantinople and were deposed in the Church of the Holy Apostles, which had been built by him (see Homily XXVI on Second Corinthians by Saint John Chrysostom).

As for his holy mother Helen, after her son had made the Faith of Christ triumphant throughout the Roman Empire, she undertook a journey to Jerusalem and found the Holy Cross on which our Lord was crucified (see Sept. 13 and 14). After this, Saint Helen, in her zeal to glorify Christ, erected churches in Jerusalem at the sites of the Crucifixion and Resurrection, in Bethlehem at the cave where our Saviour was born, another on the Mount of Olives whence He ascended into Heaven, and many others throughout the Holy Land, Cyprus, and elsewhere. She was proclaimed Augusta, her image was stamped upon golden coins, and two cities were named Helenopolis after her in Bithynia and in Palestine. Having been thus glorified for her piety, she departed to the Lord being about eighty years of age, according to some in the year 330, according to others, in 336.
