The heresiarch Arius was a Libyan by race and a protopresbyter of the Church of Alexandria. In 315, he began to blaspheme against the Son and Word of God, saying that He is not true God, consubstantial with the Father, but is rather a work and creation, alien to the essence and glory of the Father, and that there was a time when He was not. This frightful blasphemy shook the faithful of Alexandria. Alexander, his Archbishop, after trying in vain to correct him through admonitions, cut him off from communion and finally in a local council deposed him in the year 321. Yet neither did the blasphemer wish to be corrected, nor did he cease sowing the deadly tares of his heretical teachings; but writing to the bishops of other cities, Arius and his followers requested that his doctrine be examined, and if it were unsound, that the correct teaching be declared to him. By this means, his heresy became universally known and won many supporters, so that the whole Church was soon in an uproar.

Therefore, moved by divine zeal, the first Christian Sovereign, Saint Constantine the Great, the equal to the Apostles, summoned the renowned First Ecumenical Council in Nicaea, a city of Bithynia. It was there that the shepherds and teachers of the Church of Christ gathered from all regions in the year 325. All of them, with one mouth and one voice, declared that the Son and Word of God is one in essence with the Father, true God of true God, and they composed the holy Symbol of Faith up to the seventh article (since the remainder, beginning with "And in the Holy Spirit," was completed by the Second Ecumenical Council). Thus they anathematized the impious Arius of evil belief and those of like mind with him, and cut them off as rotten members from the whole body of the faithful.

Therefore, recognizing the divine Fathers as heralds of the Faith after the divine Apostles, the Church of Christ has appointed this present Sunday for their annual commemoration, in thanksgiving and unto the glory of God, unto their praise and honour, and unto the strengthening of the true Faith.

Saint Dorotheus became Bishop of Tyre in Phoenicia about the end of the third century. During the persecution of Diocletian and Maximian, about the year 303, he fled to Odyssopolis in Thrace to preserve his life, and after the death of the tyrants he returned to Tyre. He lived until the reign of Julian the Apostate (361-363), from whose persecution he again fled to Odyssopolis (or, according to Theophylact of Bulgaria, Edessa), but was found by Julian's men and slain in great torments, at the age of 107, in 361. He was very learned, and has left behind writings in both Latin and Greek relating the lives of the holy Prophets, Apostles, and other Saints.

Saint Bartholomew was one of the Twelve Apostles, and had Galilee as his homeland; this is all that is known of him for certain according to the history of the Gospels. Concerning his apostolic work, certain say that he preached in Arabia and Persia, and especially in India, bringing to them the Gospel written by Saint Matthew, which had been written originally in Hebrew, and which was found there one hundred years later by Pantaenus, formerly a stoic philosopher and later an illustrious teacher of the Christian school in Alexandria (see Eusebius, Eccl. Hist., 5: 10). Other accounts say that he went to Armenia. According to some, he ended his life by being crucified, or by being flayed alive, in Albanopolis (Urbanopolis) of Armenia. This also confirms an ancient tradition preserved by the Armenians. According to some, Bartholomew and Nathanael are the same person, because the Evangelists who mention Bartholomew do not mention Nathanael; and John, who alone mentions Nathanael as one of the Twelve, says nothing of Bartholomew. Indeed, Bartholomew is a patronymic, "son of Talmai," which means "bold, spirited" (see also Jesus of Navi 15:14; II Kings 3:3), and Nathanael could have had this as a surname. According to the Synaxarion of the Menaion on April 22, however, it is Simon the Zealot and Nathanael who are the same; the Evangelists who mention Simon the Zealot (or "the Canaanite") do not mention Nathanael.

Saint Barnabas, one of the Seventy, was from Cyprus, of the tribe of Levi, and a fellow disciple with Paul under Gamaliel. He was called Joses, but was renamed Barnabas, which means "son of consolation," perhaps to distinguish him from the Joses called Barsabas and surnamed Justus (Acts 1:23). Saint Barnabas had a field, which he sold and brought the money to the Apostles (Acts 4:36-37). Before the conversion of Saul to Paul, it was Barnabas who was the leader of the Seventy Apostles, the first in preaching and chief spokesman. After Saul's vision on the road to Damascus, it was Barnabas who joined him to the Apostles when the others, because of Saul's reputation as a persecutor of the Church, still feared him (Acts 9:26-27); again it was Saint Barnabas who conscripted Paul as a preacher, bringing him from Tarsus to Antioch after the stoning of Stephen, to assist in spreading the Gospel (Acts 11:25-26). Saint Barnabas preached the Gospel in many places, traveled together with Paul, and finally was stoned to death by the Jews in his native Cyprus. During the reign of Zeno, in the year 478, his sacred relics were found, having on his chest the Gospel according to Matthew written in Greek by Barnabas' own hand. This Gospel was brought to Zeno. Because of this the Church of Cyprus received the right of autonomy, and its archbishop was given the privilege, like the emperor, of signing his decrees and encyclicals in vermilion.

After the Saviour's Ascension into the Heavens, the eleven Apostles and the rest of His disciples, the God-loving women who followed after Him from the beginning, His Mother, the most holy Virgin Mary, and His brethren-all together about 120 souls returned from the Mount of Olives to Jerusalem. Entering into the house where they gathered, they went into the upper room, and there they persevered in prayer and supplication, awaiting the coming of the Holy Spirit, as their Divine Teacher had promised them. In the meanwhile, they chose Matthias, who was elected to take the place of Judas among the Apostles.

Thus, on this day, the seventh Sunday of Pascha, the tenth day after the Ascension and the fiftieth day after Pascha, at the third hour of the day from the rising of the sun, there suddenly came a sound from Heaven, as when a mighty wind blows, and it filled the whole house where the Apostles and the rest with them were gathered. Immediately after the sound, there appeared tongues of fire that divided and rested upon the head of each one. Filled with the Spirit, all those present began speaking not in their native tongue, but in other tongues and dialects, as the Holy Spirit instructed them.

The multitudes that had come together from various places for the feast, most of whom were Jews by race and religion, were called Parthians, Medes, Elamites, and so forth, according to the places where they dwelt. Though they spoke many different tongues, they were present in Jerusalem by divine dispensation. When they heard that sound that came down from Heaven to the place where the disciples of Christ were gathered, all ran together to learn what had taken place. But they were confounded when they came and heard the Apostles speaking in their own tongues. Marvelling at this, they said one to another, "Behold, are not all these which speak Galileans? And how hear we every man in our own tongue, wherein we were born?" But others, because of their foolishness and excess of evil, mocked the wonder and said that the Apostles were drunken.

Then Peter stood up with the eleven, and raising his voice, spoke to all the people, proving that that which had taken place was not drunkenness, but the fulfilment of God's promise that had been spoken by the Prophet Joel: "And it shall come to pass in the last days, that I shall pour out of My Spirit upon all flesh, and your sons and daughters shall prophesy" (Joel 2:28), and he preached Jesus of Nazareth unto them, proving in many ways that He is Christ the Lord, Whom the Jews crucified but God raised from the dead. On hearing Peter's teaching, many were smitten with compunction and received the word. Thus, they were baptized, and on that day about three thousand souls were added to the Faith of Christ.

Such, therefore, are the reasons for today's feast: the coming of the All-holy Spirit into the world, the completion of the Lord Jesus Christ's promise, and the fulfilment of the hope of the sacred disciples, which we celebrate today. This is the final feast of the great mystery and dispensation of God's incarnation. On this last, and great, and saving day of Pentecost, the Apostles of the Saviour, who were unlearned fishermen, made wise now of a sudden by the Holy Spirit, clearly and with divine authority spoke the heavenly doctrines. They became heralds of the truth and teachers of the whole world. On this day they were ordained and began their apostleship, of which the salvation of those three thousand souls in one day was the comely and marvellous first fruit.

Some erroneously hold that Pentecost is the "birthday of the Church." But this is not true, for the teaching of the holy Fathers is that the Church existed before all other things. In the second vision of The Shepherd of Hermas we read: "Now brethren, a revelation was made unto me in my sleep by a youth of exceeding fair form, who said to me, 'Whom thinkest thou the aged woman, from whom thou receivedst the book, to be?' I say, 'The Sibyl.' 'Thou art wrong,' saith he, 'she is not.' 'Who then is she?' I say. 'The Church,' saith he. I said unto him, 'Wherefore then is she aged?' 'Because,' saith he, 'she was created before all things; therefore is she aged, and for her sake the world was framed."' Saint Gregory the Theologian also speaks of "the Church of Christ ... both before Christ and after Christ" (PG 35:1108-9). Saint Epiphanius of Cyprus writes, "The Catholic Church, which exists from the ages, is revealed most clearly in the incarnate advent of Christ" (PG 42:640). Saint John Damascene observes, "The Holy Catholic Church of God, therefore, is the assembly of the holy Fathers, Patriarchs, Prophets, Apostles, Evangelists, and Martyrs who have been from the very beginning, to whom were added all the nations who believed with one accord" (PG 96, 1357c). According to Saint Gregory the Theologian, "The Prophets established the Church, the Apostles conjoined it, and the Evangelists set it in order" (PG 35, 589 A). The Church existed from the creation of the Angels, for the Angels came into existence before the creation of the world, and they have always been members of the Church. Saint Clement, Bishop of Rome, says in his second epistle to the Corinthians, the Church "was created before the sun and moon"; and a little further on, "The Church existeth not now for the first time, but hath been from the beginning" (II Cor. 14).

That which came to pass at Pentecost, then, was the ordination of the Apostles, the commencement of the apostolic preaching to the nations, and the inauguration of the priesthood of the new Israel. Saint Cyril of Alexandria says that "Our Lord Jesus Christ herein ordained the instructors and teachers of the world and the stewards of His divine Mysteries ... showing together with the dignity of Apostleship, the incomparable glory of the authority given them ... Revealing them to be splendid with the great dignity of the Apostleship and showing them forth as both stewards and priests of the divine altars . . . they became fit to initiate others through the enlightening guidance of the Holy Spirit" (PG 74, 708-712). Saint Gregory Palamas says, "Now, therefore ... the Holy Spirit descended ... showing the Disciples to be supernal luminaries ... and the distributed grace of the Divine Spirit came through the ordination of the Apostles upon their successors" (Homily 24, 10). And Saint Sophronius, Bishop of Jerusalem, writes, "After the visitation of the Comforter, the Apostles became high priests" (PG 87, 3981B). Therefore, together with the baptism of the Holy Spirit which came upon them who were present in the upper chamber, which the Lord had foretold as recorded in the Acts, "ye shall be baptized with the Holy Spirit not many days hence" (Acts 1:5), the Apostles were also appointed and raised to the high priestly rank, according to Saint John Chrysostom (PG 60, 21). On this day commenced the celebration of the Holy Eucharist by which we become "partakers of the Divine Nature" (II Peter 1:4). For before Pentecost, it is said of the Apostles and disciples only that they abode in "prayer and supplication" (Acts 1:14); it is only after the coming of the Holy Spirit that they persevered in the "breaking of bread,"that is, the communion of the Holy Mysteries-"and in prayer" (Acts 2:42).

The feast of holy Pentecost, therefore, determined the beginning of the priesthood of grace, not the beginning of the Church. Henceforth, the Apostles proclaimed the good tidings "in country and town," preaching and baptizing and appointing shepherds, imparting the priesthood to them whom they judged were worthy to minister, as Saint Clement writes in his first Epistle to the Corinthians (I Cor. 42).
