{15} And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the {r} chief corner stone;

(15) The Lord committed the doctrine of salvation, first to the prophets, and then to the apostles, the end of which, and matter as it were and substance, is Christ. Therefore that is indeed the true and universal Church which is built upon Christ by the prophets and apostles, as a spiritual temple consecrated to God.

(r) That is the corner stone of the building, for the foundations are as it were corner stone of the building.

People's New Testament

2:20 Built upon the foundation of the apostles and prophets. They have been built into the temple of the Lord. The word of God, declared by apostles and prophets, is the foundation of their faith,

Jesus Christ himself being the chief corner stone. The corner-stone was a stone of double size at the corner, which became a part of both walls and joined them together. So he had joined the Jews and Gentiles in the building. He is the foundation-stone on which the building rests, and the stone of union. Compare Isa 28:16 Mt 21:42 Ac 4:11 1Pe 2:7.

Wesley's Notes

2:20 And are built upon the foundation of the apostles and prophets - As the foundation sustains the building, so the word of God, declared by the apostles and prophets, sustains the faith of all believers. God laid the foundation by them; but Christ himself is the chief corner - stone of the foundation. Elsewhere he is termed the foundation itself, 1Cor 3:11.

Jamieson-Fausset-Brown Bible Commentary

20. Translate as Greek, "Built up upon," &c. (participle; having been built up upon; omit, therefore, "and are"). Compare 1Co 3:11, 12. The same image in Eph 3:18, recurs in his address to the Ephesian elders (Ac 20:32), and in his Epistle to Timothy at Ephesus (1Ti 3:15; 2Ti 2:19), naturally suggested by the splendid architecture of Diana's temple; the glory of the Christian temple is eternal and real, not mere idolatrous gaud. The image of a building is appropriate also to the Jew-Christians; as the temple at Jerusalem was the stronghold of Judaism; as Diana's temple, of paganism.

foundation of the apostles, &c.-that is, upon their ministry and living example (compare Mt 16:18). Christ Himself, the only true Foundation, was the grand subject of their ministry, and spring of their life. As one with Him and His fellow workers, they, too, in a secondary sense, are called "foundations" (Re 21:14). The "prophets" are joined with them closely; for the expression is here not "foundations of the apostles and the prophets," but "foundations of the apostles and prophets." For the doctrine of both was essentially one (1Pe 1:10, 11; Re 19:10). The apostles take the precedency (Lu 10:24). Thus he appropriately shows regard to the claims of the Jews and Gentiles: "the prophets" representing the old Jewish dispensation, "the apostles" the new. The "prophets" of the new also are included. Bengel and Alford refer the meaning solely to these (Eph 3:5; 4:11). These passages imply, I think, that the New Testament prophets are not excluded; but the apostle's plain reference to Ps 118:22, "the head stone of the corner," proves that the Old Testament prophets are a prominent thought. David is called a "prophet" in Ac 2:30. Compare also Isa 28:16; another prophet present to the mind of Paul, which prophecy leans on the earlier one of Jacob (Ge 49:24). The sense of the context, too, suits this: Ye were once aliens from the commonwealth of Israel (in the time of her Old Testament prophets), but now ye are members of the true Israel, built upon the foundation of her New Testament apostles and Old Testament prophets. Paul continually identifies his teaching with that of Israel's old prophets (Ac 26:22; 28:23). The costly foundation-stones of the temple (1Ki 5:17) typified the same truth (compare Jer 51:26). The same stone is at once the corner-stone and the foundation-stone on which the whole building rests. Paul supposes a stone or rock so large and so fashioned as to be both at once; supporting the whole as the foundation, and in part rising up at the extremities, so as to admit of the side walls meeting in it, and being united in it as the corner-stone [Zanchius]. As the corner-stone, it is conspicuous, as was Christ (1Pe 2:6), and coming in men's way may be stumbled over, as the Jews did at Christ (Mt 21:42; 1Pe 2:7).

Matthew Henry's Concise Commentary

2:19-22 The church is compared to a city, and every converted sinner is free of it. It is also compared to a house, and every converted sinner is one of the family; a servant, and a child in God's house. The church is also compared to a building, founded on the doctrine of Christ; delivered by the prophets of the Old Testament, and the apostles of the New. God dwells in all believers now; they become the temple of God through the working of the blessed Spirit. Let us then ask if our hopes are fixed on Christ, according to the doctrine of his word? Have we devoted ourselves as holy temples to God through him? Are we habitations of God by the Spirit, are we spiritually-minded, and do we bring forth the fruits of the Spirit? Let us take heed not to grieve the holy Comforter. Let us desire his gracious presence, and his influences upon our hearts. Let us seek to discharge the duties allotted to us, to the glory of God.
