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.

He that was greater than all who are born of women, the Prophet who received God's testimony that he surpassed all the Prophets, was born of the aged and barren Elizabeth (Luke 1: 7) and filled all his kinsmen, and those that lived round about, with gladness and wonder. But even more wondrous was that which followed on the eighth day when he was circumcised, that is, the day on which a male child receives his name. Those present called him Zacharias, the name of his father. But the mother said, "Not so, but he shall be called John." Since the child's father was unable to speak, he was asked, by means of a sign, to indicate the child's name. He then asked for a tablet and wrote, "His name is John." And immediately Zacharias' mouth was opened, his tongue was loosed from its silence of nine months, and filled with the Holy Spirit, he blessed the God of Israel, Who had fulfilled the promises made to their fathers, and had visited them that were sitting in darkness and the shadow of death, and had sent to them the light of salvation. Zacharias prophesied concerning the child also, saying that he would be a Prophet of the Most High and Forerunner of Jesus Christ. And the child John, who was filled with grace, grew and waxed strong in the Spirit; and he was in the wilderness until the day of his showing to Israel (Luke 1:57-80). His name is a variation of the Hebrew "Johanan," which means "Yah is gracious."

The divinely-blessed Peter was from Bethsaida of Galilee. He was the son of Jonas and the brother of Andrew the First-called. He was a fisherman by trade, unlearned and poor, and was called Simon; later he was renamed Peter by the Lord Jesus Christ Himself, Who looked at him and said, "Thou art Simon the son of Jonas; thou shalt be called Cephas (which is by interpretation, Peter)" (John 1:42). On being raised by the Lord to the dignity of an Apostle and becoming inseparable from Him as His zealous disciple, he followed Him from the beginning of His preaching of salvation up until the very Passion, when, in the court of Caiaphas the high priest, he denied Him thrice because of his fear of the Jews and of the danger at hand. But again, after many bitter tears, he received complete forgiveness of his transgression. After the Resurrection of Christ and the descent of the Holy Spirit, he preached in Judea, Antioch, and certain parts of Asia, and finally came to Rome, where he was crucified upside down by Nero, and thus he ascended to the eternal habitations about the year 66 or 68, leaving two Catholic (General) Epistles to the Church of Christ.

Paul, the chosen vessel of Christ, the glory of the Church, the Apostle of the Nations and teacher of the whole world, was a Jew by race, of the tribe of Benjamin, having Tarsus as his homeland. He was a Roman citizen, fluent in the Greek language, an expert in knowledge of the Law, a Pharisee, born of a Pharisee, and a disciple of Gamaliel, a Pharisee and notable teacher of the Law in Jerusalem. For this cause, from the beginning, Paul was a most fervent zealot for the traditions of the Jews and a great persecutor of the Church of Christ; at that time, his name was Saul (Acts 22:3-4). In his great passion of rage and fury against the disciples of the Lord, he went to Damascus bearing letters of introduction from the high priest. His intention was to bring the disciples of Christ back to Jerusalem in bonds. As he was approaching Damascus, about midday there suddenly shone upon him a light from Heaven. Falling on the earth, he heard a voice saying to him, "Saul, Saul, why persecutest thou Me?" And he asked, "Who art Thou, Lord?" And the Lord said, "I am Jesus Whom thou persecutest; it is hard for thee to kick against the pricks." And that heavenly voice and brilliance made him tremble, and he was blinded for a time. He was led by the hand into the city, and on account of a divine revelation to the Apostle Ananias (see Oct. 1), he was baptized by him, and both his bodily and spiritual eyes were opened to the knowledge of the Sun of Righteousness. And straightway- O wondrous transformation! - beyond all expectation, he spoke with boldness in the synagogues, proclaiming that "Christ is the Son of God" (Acts 9:1-21). As for his zeal in preaching the Gospel after these things had come to pass, as for his unabating labors and afflictions of diverse kinds, the wounds, the prisons, the bonds, the beatings, the stonings, the shipwrecks, the journeys, the perils on land, on sea, in cities, in wildernesses, the continual vigils, the daily fasting, the hunger, the thirst, the nakedness, and all those other things that he endured for the Name of Christ, and which he underwent before nations and kings and the Israelites, and above all, his care for all the churches, his fiery longing for the salvation of all, whereby he became all things to all men, that he might save them all if possible, and because of which, with his heart aflame, he continuously traveled throughout all parts, visiting them all, and like a bird of heaven flying from Asia and Europe, the West and East, neither staying nor abiding in any one place - all these things are related incident by incident in the Book of the Acts, and as he himself tells them in his Epistles. His Epistles, being fourteen in number, are explained in 250 homilies by the divine Chrysostom and make manifest the loftiness of his thoughts, the abundance of the revelations made to him, the wisdom given to him from God, wherewith he brings together in a wondrous manner the Old with the New Testaments, and expounds the mysteries thereof which had been concealed under types; he confirms the doctrines of the Faith, expounds the ethical teaching of the Gospel, and demonstrates with exactness the duties incumbent upon every rank, age, and order of man. In all these things his teaching proved to be a spiritual trumpet, and his speech was seen to be more radiant than the sun, and by these means he clearly sounded forth the word of truth and illumined the ends of the world. Having completed the work of his ministry, he likewise ended his life in martyrdom when he was beheaded in Rome during the reign of Nero, at the same time, some say, when Peter was crucified.
