Matthew Poole and continuators on Ephesians 2:20

20. And are built upon the foundation of the apostles and prophets , Jesus Christ himself being the chief corner stone .

The foundation which the Apostles and Prophets laid by their Preaching, viz. Christ whom they held forth as the onely Mediatour between God and Man, the onely Saviour and Head of the Church: see 1 Cor. 3.11. Foundation in the Singular Number, to imply the unity of their Doctrine centring in Christ, Apostles and Prophets, whose Office was to Preach, not Kings and Patriarchs.

As both supporting the building by his strength, and uniting the several parts of it, Iew and Gentile: see Mat. 21.42. Psal. 118.22. They that are of chief Authority are called the corners of a People, as sustaining the greatest burthen, 1 Sam. 14.38. Isai. 19.13. Obj. If Christ be the corner Stone, how is he the Foundation? Ans. The same thing may have different denominations in different respects; Christ is called a Foundation 1 Cor. 3.11. a corner Stone, 1 Pet. 2.6. a Temple, Ioh. 2.19. a Door, Ioh. 10.7. a Builder, Mat. 16.18. so here again a corner Stone, and yet laid for a Foundation, Isai. 28.16.
