Therefore thus says the Lord GOD,
Behold, I lay in Zion for a foundation a stone, a tested stone, a precious cornerstone, a sure foundation: he that believes shall not be in haste.
Read Chapter 28
Ambrose of Milan
The foundation of justice therefore is faith, for the hearts of the just dwell on faith. And the just man that accuses himself builds justice on faith, for his justice becomes plain when he confesses the truth. So the Lord says through Isaiah: “Behold, I lay a stone for a foundation in Zion.” This means Christ as the foundation of the church. For Christ is the object of faith to all; but the church is as it were the outward form of justice; it is the common right of all. - "Duties of the Clergy 1.29"
Here is what one believes with the heart unto justice and makes confession of with the mouth unto salvation. But you’re afraid to confess it, in case people taunt you with it; and not ones who have not come to believe, because they too believe it inwardly. But in case those who are ashamed to confess it should taunt you with it, listen to what comes next. For Scripture says, “Nobody who believes in him shall be put to shame.” Reflect on all this; stick to it all. This is prey, food not for the belly but for the intelligence. - "Sermon 279.9"
To the one group, the infant at birth is shown as the chief cornerstone announced by the prophet; to the other group he is manifested at the very outset of his career. He has already begun to weld together in himself the two walls originally set in different directions, bringing shepherds from Judea and magi from the East. - "Sermon 199.1"
Therefore, with the exception of this cornerstone, I do not see how people are to be built into a house of God, to contain God dwelling in them, without being born again, which cannot happen before they are born. - "Letter 187.31"
A stone anointed; why a stone? “Behold, I lay in Zion a stone, elect, precious; and he that believes on him shall not be confounded.” Why anointed? Because Christ comes from “anointing” (chrisma). - "Tractates on the Gospel of John 7.23"
Was his tomb made with hands? Does it rise above the ground, like the tombs of kings? Was the sepulcher made of stones joined together? And what is laid upon it? Tell us exactly, O prophets, about his tomb also, where it lies, and where we shall look for it. But they answer, “Look upon the solid rock which you have hewn,” look and see.… I, who am “the chief corner stone, chosen, precious,” lie for a while within a stone, I, who am “a stone of stumbling” to the Jews but of salvation to them that believe. - "Catechetical Lectures 13.35"
Who can the cornerstone be other than the one who is the living and precious stone supporting two structures with his teaching making them one? He established the building of Moses, which was to remain until his day, and then he joined on to one side our building of the gospel. This is why he is called the cornerstone. - "Proof of the Gospel 1.7"
Jacob, hastening to seek a bride, met Rachel unexpectedly at the well. And a great stone lay upon the well, which a multitude of shepherds were [accustomed] to roll away when they came together and then gave water to themselves and to their flocks. But Jacob alone rolls away the stone and waters the flocks of his spouse. The thing is, I think, a dark saying, a shadow of what should come. For what is the stone that is laid but Christ? For of him Isaiah says, “And I will lay in the foundations of Zion a costly stone, precious, elect”; and Daniel likewise, “A stone was cut out but not by hand,” that is, Christ was born without a man. - "On the Baptism of Christ"
Peter also spoke confidently about this stone of assistance: “This is the stone rejected by you builders, which was made the cornerstone.” And Isaiah said, “Behold, I will lay a cornerstone in Zion as its foundation, elect and precious; the one who believes in it will not be ashamed.”
“Therefore I say to you that the kingdom of God will be taken from you and given to the people who produce its fruit.” As I have said, the kingdom of God is often to be understood as sacred Scripture, which the Lord removed from the Jews and gave to us that we might produce its fruits. This is the vineyard that was given to the tenant farmers and vinedressers who did no work in it; possessing the Scriptures in name only, they will lose the fruits of the vineyard.
“Whoever falls on this stone will be broken, but the one upon whom it falls will be destroyed.” It is one thing to offend Christ through evil deeds but another thing to deny him. The sinner who nevertheless still believes in him is the one who fa...
This cornerstone joins together both walls and restores two peoples to unity, concerning which God said through Isaiah: “Behold, I will lay a cornerstone in Zion as its foundation, elect and precious; the one who believes in it will not be ashamed.” It was his will to build further upon this cornerstone and other cornerstones, so that the apostle Paul would be able to say boldly, “built upon the foundation of the apostles and the prophets, with Jesus Christ himself being the chief cornerstone.” - "Commentary on Zechariah 3.14.10–11"
Your stone is one that ruin follows and the disastrous collapse of tumbling towers; but our stone, laid by the hand of God, builds up, strengthens, lifts, fortifies and adorns the grace of the restored work with the splendor of everlasting immortality.
For Isaiah says of this at the behest of the Holy Spirit: “Thus says the Lord: Behold, I lay a stone for the foundations of Zion, a precious stone, elect, a chief cornerstone, honored, and he that shall believe in it shall not be confounded.” - "Error of the Pagan Religions 20"
Therefore, brothers, we should be careful neither to give scandal to others nor to take it ourselves when another gives it. It is scandal that troubles the senses, perturbs the mind, confuses our judgment otherwise sharp. It is a scandal that changed an angel into the devil, an apostle into a traitor; that brought sin into the world and allured humankind to death.… Scandal tempts the saints, fatigues the cautious, throws down the incautious, disturbs all things, confuses all people.… He uttered a warning to keep anyone else from coming to this, by saying, “It is impossible that scandals should not come; but woe to him through whom they come! It would be better for him if a millstone were hung about his neck and he were thrown into the sea, rather than that he should cause one of these little ones to sin.”
Why a millstone and not an ordinary stone? Because, while a millstone is grinding the grain, and pouring out the flour and separating the bran from the meal, it is simultaneously furn...
Isaiah wrote, “Behold, I lay a cornerstone in Zion as its foundation, elect and precious; he who believes in it will not be ashamed.” The cornerstone is Christ, who, when Nathaniel came to him, explained what Jacob had seen in his dream: “You will see the heavens opened and the angels of God ascending and descending upon the Son of man.” For the Christ who descended “is the same one who ascends above all the heavens that he might fill everything.” But he lays a narrow path that leads to life. - "The Book of Promises and Predictions of God 1.33–34"
