Mark 12:10

This rejected stone, which is borne by that corner where the lamb and the bread met in the supper, ending the Old and beginning the New Testament, does things marvellous in our eyes as the topaz. (Ps. 118, Ps. 127. Vulg.)

(ubi sup.) But that this was done by Divine interposition he affirms, by immediately afterwards adding, And have ye not read this Scripture, The stone which the builders refused is become the head-stone in the corner? As if he had said, how is this prophecy to be fulfilled, save in that Christ, being rejected and slain by you, is to be preached to the Gentiles, who will believe on Him? Thus then as a corner stone, He will found the two people on Himself, and of the two people will build for Himself a city of the faithful, one temple. For the masters of the synagogue, whom He had just called husbandmen, He now calls builders, because the same persons, who seemed to cultivate His people, that they might bear the fruits of life, like a vineyard, were also commanded to construct and adorn this people, to be, as it were, a house worthy to have God for its inhabitant.

Have you not read this Scripture: The stone that the builders rejected has become the cornerstone? This was the Lord's doing, and it is marvelous in our eyes. How, he says, will this prophecy be fulfilled, that the stone rejected by the builders is said to be placed as the cornerstone, unless because Christ, rejected and killed by you, is to be preached to the Gentiles who will believe, so that, like a cornerstone, he may unite the two in himself and build from both peoples one faithful city for himself, one temple? For he now calls the same synagogue teachers, whom he previously called tenants, builders. For those who were commanded to cultivate the people subject to them to bear the fruits of life, like a vineyard, were also commanded to construct and adorn it as a house worthy of God as its inhabitant. Hence, the Apostle, writing to the faithful, says: You are God's field, God's building (I Cor. III). But those who refused to return the fruit of God's vineyard to the great householder, like the worst tenants, the same, like evil masons, strive to remove from the house of God the precious and chosen stone, which was to be placed either in the foundation or in the corner, that is, they sought to take away the faith of Christ from their listeners.
