It is not inconsistent with this, that the twelve apostles, of whom Peter was one, are called twelve foundation stones,[51] upon which, as John says, the city of God, that descended from heaven, was built. Rev. 21:14. For, even if it were admitted that by the words, _city of God_, in this place, there is to be understood the church of God here on earth, this would only prove, that Peter, as well as the other apostles, was one of the twelve foundation stones of the church of Christ; which by no means confirms the proposed objection, _that Peter alone is the foundation stone, or foundation, of the church_. [51] “The wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb.” Rev. 21:14. In the first place it is questionable (even if it be admitted that by this description of the city of God we are to understand the church of God) whether thereby is meant the church of God as it is here on earth, or the glorified church of God, as it will be afterwards in heaven; for only the former, and not the latter, is to be considered here. In the second place, it is certain that the name “_foundation stone_” is ascribed here not to Peter alone, but to all the twelve apostles; hence he is here called a foundation not any more than any of the others. Again, the word “_foundation stones_” here does not signify the foundation itself, since, properly speaking, in nature, the foundation, as the ground or bottom of a building, is something different from the stones built upon it, which are called foundation stones; for, upon the ground or bottom the foundation-stones are laid, and upon the foundation-stones the building; so that the ground of foundation must support both, the foundation-stones and the building. Thus, Christ is the ground, bottom, or foundation of his church; the apostles, through their doctrine, are the foundation-stones; and the church is the building erected upon these foundation-stones and the foundation. It stands fast, therefore, that they err, who make Peter the only foundation of the church of Christ, and that, consequently the building which they erect thereon, is erroneous and false.[52] [52] “James, Cephas” (or Peter), “and John, who seemed to be pillars,” etc. Gal. 2:9. Here James is mentioned before Cephas (or Peter). Again, John and James are called pillars as well as Cephas (or Peter), in order to show that the worthiness or the ministry of one was not more than that of the other, and that they, without distinction, were all equal therein. REPLY TO THE SECOND PASSAGE. The second passage is taken from Matt. 16:19: “And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven; and whatsoever thou shalt loose on earth shall be loosed in heaven.”
