Acts 1:13

“"And when they were come in," it says, "they went up into an upper room, where they were making their abode:" so they then remained in Jerusalem after the Resurrection: "both Peter, and James, and John:" no longer is only the latter together with his brother mentioned, but together with Peter the two: "and Andrew, and Philip, and Thomas, Bartholomew, and Matthew, and James (the son) of Alphaeus, and Simon Zelotes, and Judas, (the brother) of James." He has done well to mention the disciples: for since one had betrayed Christ, and another had been unbelieving, he thereby shows that, except the first, all of them were preserved. They durst not appear in the town. They also did well to go up into an upper room, as it became less easy to arrest them at once.”

“[Daniel 6:10] "Now when Daniel learned of it, that is, of the law which had been enacted, he entered his house, and with the windows in his upper room opened up in the direction of Jerusalem, he continued to bow his knees three times a day and worshipped, and made confession before his God just as he was previously accustomed to do." We must quickly draw from our memory and bring together from all of Holy Scripture all the passages where we have read of domata, which mean in Latin either "walled enclosures" (menia) or "beds" or "sun-terraces," and also the references to anogaia, that is, "upper rooms." For after all, our Lord celebrated the passover in an upper room (Mark 14:15, Luke 22:12), and in the Acts of the Apostles the Holy Spirit came upon the one hundred and twenty souls of believers while they were in an upper room (Acts 1:13). And so Daniel in this case, despising the king's commands and reposing his confidence in God, does not offer his prayers in some obscure spot, but in a lofty place, and opens up his windows towards Jerusalem, from whence he looked for the peace . He prays, moreover, according to God's behest, and also according to what Solomon had said when he admonished the people that they should pray in the direction of the Temple. Furthermore, there are three times in the day when we should bow our knees unto God, and the tradition of the Church understands them to be the third hour, the sixth hour, and the ninth hour. Lastly, it was at the third hour that the Holy Spirit descended upon the Apostles (Acts 2:15) . It was at the sixth hour that Peter, purposing to eat, ascended to the upper room for prayer (Acts 10:9). It was at the ninth hour that Peter and John were on their way to the Temple (Acts 3:1).”

“Now although they lived beforehand the life of freedom, as a pledge, yet they did not receive this freedom in themselves until they had first of all laboured in the life of abstinence, for it is written concerning them that immediately our Redeemer was taken up they returned to that upper chamber in which they were abiding, and that they lived there with much fasting, and in close confinement, and with sincere prayers, and bitter weeping, and that afterwards they were held to be worthy to receive the Paraclete. And if from the ascension of Christ into heaven, unto the descent of the Spirit the days of their abstinence were few, we must learn that they also tarried in this service of fasting and abstinence after they had received the Spirit, and in every place is it written concerning them that they fasted and prayed.”

“James of Alphaeus, and Simon the Zealot, and Judas of James. Some think that there were two apostles called James, namely James of Zebedee and James of Alphaeus, and that the third James, the brother of the Lord, was not an apostle but the bishop of Jerusalem. That is by no means true, but according to the faith of the Gospels, it should be known that this same James, the son of Alphaeus and an apostle, was in charge of Jerusalem, who was called the brother of the Lord, because he was the son of the Lord's maternal aunt, of whom John the evangelist mentions. However, he says, "standing by the cross of Jesus were his mother, and his mother's sister, Mary of Clopas" (John 19). Naming this Mary of Clopas from her father or family. For how could the brother of the Lord be said to be not an apostle but the third James, when Paul also names him an apostle: "But I saw none of the other apostles except James, the brother of the Lord" (Galatians 1)? And the evangelist Mark calls him the same, not the third but the other, saying: "There were also women looking on from afar, among whom were Mary Magdalene, and Mary the mother of James the Younger and Joses, and Salome" (Mark 15). For since "greater" and "lesser" usually provide a distinction not among three but between two, the lesser James is called the son of Alphaeus, in distinction from the greater who was the son of Zebedee. Read the book of blessed Jerome against Helvidius. However, Simon the Zealot is the one who is written in the Gospels as the Canaanite. For Cana interprets as zeal. He was from a village in Galilee, Cana, where the Lord turned water into wine, and after his brother James, he ruled the Church of Jerusalem and at the age of one hundred and twenty ascended the cross under Trajan. He is declared to be according to the flesh a cousin of the Savior, because Hegesippus testified that his father Clopas was the brother of Joseph. And Judas of James, that is, the brother of James, is the same as the one called Thaddeus in the Gospels, and he was sent to Edessa to Abgarus, the king of Osroene, as ecclesiastical history tells. It continues:”

“Peter, interpreting or knowing: James, supplanter of labor. John, by the grace of God: Andrew, becoming powerful or condemned: Philip, the mouth of widows or the mouth of the lamp: Thomas, the abyss or twin or doubting. Bartholomew, son of him who suspends waters: Matthew, gifted: James son of Alphaeus, supplantation. Simon the Zealot, discipline of life: Judas son of James, he was also called Thaddeus. He names the disciples individually to show that, since they had fallen away at the time of the passion, Judas indeed completely cast himself out from the band of the apostles. But Peter agreed, and through the threefold question was summoned back to the Teacher. And if John is recorded among the same as taking the Mother of Christ, yet with John present to the apostles, she herself was also present.”

“He does not compile a list of the disciples in vain: but wishing to show that they had suffered something human, yet had not remained in apostasy. For indeed Peter, who had denied, was absolved from his denial by bitter tears, as is made evident from this, that shortly afterwards the spiritual flock was entrusted to him. Thomas, who had been unbelieving, was healed of his unbelief when the wounds and the side were touched with his hands. Therefore, although all the others were present together, Judas alone was missing. And Mary, Mother of God, was present, as indeed was John, who had received her into his house, and the brothers were present. What if Joseph, the bridegroom, had been alive, certainly he would also have been present: especially he, who, when his sons doubted, never doubted concerning the privilege. But it is clear that he had long since died: for he himself was not then present, when his kinsmen wished to see Jesus teaching. For what does he say? "Your mother and your brothers are seeking you outside," (Matt. 12:47) nor is it added: "And your father."”
