Augustine of Hippo : The central place they are all coming to is Christ; he is at the center, because he is equally related to all; anything placed in the center is common to all.…Approach the mountain, climb up the mountain, and you that climb it, do not go down it. There you will be safe, there you will be protected; Christ is your mountain of refuge. And where is Christ? At the right hand of the Father, since he has ascended into heaven. — SERMON 62A.3 Augustine of Hippo : It talks of a mountain, and the mountain is veiled to the party of Donatus. …The holy Daniel saw a vision and wrote down what he saw, and he said that he had seen a stone hewn out of a mountain without hands. It is Christ, coming from the nation of the Jews, which was also a mountain, you see, because it has the kingdom.… What is the mountain over which the heretics stumbled? Listen to Daniel again: "And that stone grew and became a great mountain, such that it filled all the face of the earth." How right the psalm is to say to Christ the Lord as he rises again, "Be exalted over the heavens, O God, and let your glory be over the whole earth." What is your glory over the whole earth? Over the whole earth your church, over the whole earth your bride. — SERMON 147A.4 Cyril of Jerusalem : He calls the church a mountain when he says, "In the last days the mountain of the Lord's house shall be established." — Catechetical Lecture 21:7 Eusebius of Caesarea : One can take the time to learn in what manner the prophecies of the call of the Gentiles should be understood and that they were fulfilled only after the coming of our Savior. The beginning of the prophecy is consistent with the reality that the Lord descended not only for the salvation of the Jewish race but also for that of all people, in announcing to all peoples and all the inhabitants of the earth, "Hear, all peoples, and let the earth and all in it listen." — PROOF OF THE GOSPEL 6:13 Gregory the Dialogist : Who is meant by "mountain of strength" but our Redeemer? — Forty Gospel Homilies, Homily 33 Jerome : (Verse 2) And it shall come to pass in the last days, that the mountain of the house of the Lord shall be prepared on the top of the mountains. In the Book of Genesis, we read about the last days, where Jacob called his sons and said to them: Come, that I may tell you what shall befall you in the last days (Gen. XLIX, 1): later to Judah, from whose lineage Christ was born, he said: The prince shall not fail from Judah, nor the ruler from his thigh, until he comes to whom it is laid up: and he shall be the expectation of the nations. In his last days there will be the final hour, of which the Apostle John speaks: Little children, it is the last hour (2 John 1:18); in which a stone cut without hands grew into a great mountain and filled the whole earth: from which the prince of Tyre is said to be wounded in Ezekiel (Ezekiel 8:16, according to the Septuagint). This mountain is in the house of the Lord, which the Prophet longs for, saying: One thing I have asked of the Lord, this I will seek: that I may dwell in the house of the Lord all the days of my life (Psalms 27:4); and of which Paul writes to Timothy: But if I delay, I write so that you may know how it is necessary to conduct yourself in the house of God, which is the Church of the living God, the pillar and foundation of truth (1 Timothy 3:15). This house has been built upon the foundation of the Apostles and Prophets, who themselves are also the mountains, as imitators of Christ (Ephesians 2). Of this house, the Psalmist proclaims: Those who trust in the Lord are like Mount Zion, which will not be moved forever, those who dwell in Jerusalem. Mountains surround it, and the Lord surrounds his people (Psalms 125:1). Therefore, Christ builds the Church upon one of the mountains and says to him: You are Peter, and upon this rock I will build my Church, and the gates of hell shall not prevail against it (Matthew 16:18). What does it matter to one who longs for his own soul, and eagerly desires to see the house of God, that the saint speaks: Why are you downcast, my soul, and why are you troubled? (Psalms 41:6) And again: I remembered this and poured out my soul within me, for I shall pass over to the place of the wonderful tabernacle, even to the house of God: in the voice of rejoicing and confession, the sound of those feasting. (Ibid., 5). They have moved, O Lord, your manifest mountain, and the house of God above the heads of the mountains. (Psalms 67:26). Which testimony Micah the prophet also gave in the same words, which I have explained in its place (Micah 1). And he shall be lifted up upon the hills. He who is shown and prepared on the heads of the mountains, he shall be lifted up upon the hills. Concerning those mountains and hills, in the Song of Songs the bride speaks: The voice of my brother: behold, he comes leaping upon the mountains, bounding over the hills: my brother is like a roe or a young hart on the mountains of Bethel (Song of Songs 2:8-9). And all nations shall flow unto him: all peoples shall come. For all nations shall serve him, to whom it was said: Ask of me, and I will give thee the nations for thy inheritance, and the ends of the earth for thy possession (Psalms 2:8); that they may serve him under one yoke, as the same prophet testifies: From beyond the rivers of Ethiopia my suppliants, the children of my dispersed, shall bring me an offering (Zephaniah 3:10). And in the seventy-first psalm we read: In his sight the Ethiopians shall fall down (Psalms 71:9). In the name of Jesus every knee shall bow, of those in heaven, on earth, and under the earth. — Commentary on Isaiah Leander of Seville : The mountain is Christ, and the house of the God of Jacob is his one church, toward which the concourse of nations and assembly of peoples is moving by this pronouncement. — HOMILY ON THE TRIUMPH OF THE CHURCH Theodoret of Cyrus : [Isaiah] announces the wonderful and widespread demonstration of piety everywhere: idolatry will be destroyed, while the house of God will receive its due sign of universal respect.… After our Savior's appearing, idolatry will be shown and the beauty of truth will be unveiled. In this we will see the fulfillment of this announcement. Furthermore, by "last days" he means that time following incarnation. — COMMENTARY ON Isaiah 2:2
