Bede : Now Peter and John were going up to the temple, etc. The apostles, about to enter the temple at the ninth hour, first heal a man lame from birth, and then, laboring until evening, imbue many thousands of men with the word of faith. For the teachers of the Church, coming toward the end of the world, preach both to Israel, who were first languishing, and afterwards to the Gentiles. For these are the laborers whom the father of the family brings into the vineyard at the ninth and eleventh hour (Matt. XX). — Commentary on Acts Bede : Now Peter and John were going up to the temple at the hour of prayer, the ninth hour. Which can be adapted to the previous sentence thus: Since the Lord daily was gathering the believers to his Church through the preaching of the apostles, the foremost of the apostles were going up to the temple to pray to God for the same thing, that is, so that he might always provide increases to his Church. — Retractions on Acts Cyprian : But for us, beloved brethren, besides the hours of prayer observed of old, both the times and the sacraments have now increased in number. For we must also pray in the morning, that the Lord's resurrection may be celebrated by morning prayer. And this formerly the Holy Spirit pointed out in the Psalms, saying, "My King, and my God, because unto Thee will I cry; O Lord, in the morning shalt Thou hear my voice; in the morning will I stand before Thee, and will look up to Thee." And again, the Lord speaks by the mouth of the prophet: "Early in the morning shall they watch for me, saying, Let us go, and return unto the Lord our God." Also at the sunsetting and at the decline of day, of necessity we must pray again. For since Christ is the true sun and the true day, as the worldly sun and worldly day depart, when we pray and ask that light may return to us again, we pray for the advent of Christ, which shall give us the grace of everlasting light. Moreover, the Holy Spirit in the Psalms manifests that Christ is called the day. "The stone," says He, "which the builders rejected, is become the head of the corner. This is the Lord's doing; and it is marvellous in our eyes. This is the day which the Lord hath made; let us walk and rejoice in it." Also the prophet Malachi testifies that He is called the Sun, when he says, "But to you that fear the name of the Lord shall the Sun of righteousness arise, and there is healing in His wings." But if in the Holy Scriptures the true sun and the true day is Christ, there is no hour excepted for Christians wherein God ought not frequently and always to be worshipped; so that we who are in Christ-that is, in the true Sun and the true Day-should be instant throughout the entire day in petitions, and should pray; and when, by the law of the world, the revolving night, recurring in its alternate changes, succeeds, there can be no harm arising from the darkness of night to those who pray, because the children of light have the day even in the night. For when is he without light who has light in his heart? or when has not he the sun and the day, whose Sun and Day is Christ? — Treatise IV On the Lord's Prayer Jerome : [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). — St. Jerome, Commentary on Daniel, CHAPTER SIX John Chrysostom : Everywhere we find these two Apostles in great harmony together. "To him Simon Peter beckoned." These two also "came together to the sepulchre." And concerning John, Peter said unto Christ, "And what shall this man do?" Now as for the other miracles, the writer of this book omits them; but he mentions the miracle by which they were all put in commotion. Observe again that they do not come to them purposely; so clear were they of ambition, so closely did they imitate their Master. Why now did they go up to the temple? Did they still live as Jews? No, but for expediency. — Homily on Acts 8 John Chrysostom : You observe how they continued in prayer. "The ninth hour:" there they prayed together. — Homily on Acts 8 Oecumenius : There was great unity and friendship between these two. For Peter here implies that the Lord's suffering was to be learned from the teacher, and again they ran together to the tomb, and concerning them Peter again says to Christ, "But what about this one?" (Jn. 21:21) They used to go up into the sanctuary, not any longer as those who observe Jewish customs, but appropriately and accommodatingly doing this, and so that when the lame man had been healed in the temple, they would have all who had seen it as witnesses. For many gathered there because of the reverence of the place. By indicating the hour he teaches that they were always attentive in their prayers. And he also mentions the temple, I say, relied on by both time and place for what he writes. And although many miracles were performed by the apostles, as Luke who wrote this also remembered above, he does not mention any of them by name, but he writes only that from which all began; for perhaps they overlooked those things as insignificant, or because this composition was undertaken by him not for the sake of flashiness. — Commentary on Acts Shepherd of Hermas : Having fasted frequently, and having prayed to the Lord that He would show me the revelation which He promised to show me through that old woman, the same night that old woman appeared to me, and said to me, "Since you are so anxious and eager to know all things, go into the part of the country where you tarry; and about the fifth hour I shall appear unto you, and show you all that you ought to see." ... Accordingly, I went to the country, and counted the hours, and reached the place where I had promised to meet her. ... But on coming back to myself and calling to mind the glory of God, I took courage, bent my knees, and again confessed my sins to God as I had done before. Whereupon the old woman approached, accompanied by six young men whom I had also seen before; and she stood behind me, and listened to me, as I prayed and confessed my sins to the Lord. — Shepherd of Hermas, Vision 3 Tertullian : Peter, on the day on which he experienced the vision of Universal Community, (exhibited) in that small vessel, had ascended into the more lofty parts of the house, for prayer's sake "at the sixth hour." The same (apostle) was going into the temple, with John, at the ninth hour," when he restored the paralytic to his health. — On Prayer Tertullian : For they both raised the dead, which God alone (can do), and restored the debilitated to their integrity, which none but Christ (can do); nay, they inflicted plagues too, which Christ would not do. — On Modesty
