St. Peter, Prince of the Apostles
‘By the word “rock” the Saviour cannot have meant Himself, but only Peter, as is so much more apparent in Aramaic in which the same word (Kipha) is used for “Peter” and “rock”. His statement then admits of but one explanation, namely, that He wishes to make Peter the head of the whole community of those who believed in Him as the true Messias; that through this foundation (Peter) the Kingdom of Christ would be unconquerable; that the spiritual guidance of the faithful was placed in the hands of Peter, as the special representative of Christ. This meaning becomes so much the clearer when we remember that the words “bind” and “loose” are not metaphorical, but Jewish juridical terms. It is also clear that the position of Peter among the other Apostles and in the Christian community was the basis for the Kingdom of God on earth, that is, the Church of Christ. **Peter was personally installed as Head of the Apostles by Christ Himself. This foundation created for the Church by its Founder could not disappear with the person of Peter, but was intended to continue and did continue (as actual history shows) in the primacy of the Roman Church and its bishops.

‘Objections have been raised against the genuineness of the wording of the passage, but the unanimous testimony of the manuscripts, the parallel passages in the other Gospels, and the fixed belief of pre-Constantine literature furnish the surest proofs of the genuineness and untampered state of the text of Matthew (cf. “Stimmen aus Maria Laach”, I, 1896,129 sqq.; “Theologie und Glaube”, II, 1910, 842 sqq.).’

'The word for Peter and for rock in the original Aramaic is one and the same; this renders it evident that the various attempts to explain the term “rock” as having reference not to Peter himself but to something else are misinterpretations. It is Peter who is the rock of the Church. The term ecclesia (
ekklesia) here employed is the Greek rendering of the Hebrew
qahal, the name which denoted the Hebrew nation viewed as God’s Church (see THE CHURCH, I).
’ “And upon this rock I will build my Church. . .” Here then Christ teaches plainly that in the future the Church will be the society of those who acknowledge Him, and that this Church will be built on Peter.
'The expression presents no difficulty. In both the Old and New Testaments the Church is often spoken of under the metaphor of God’s house (Numbers 12:7; Jeremiah 12:7; Hosea 8:1; 9:15; 1 Corinthians 3:9-17, Ephesians 2:20-2; 1 Timothy 3:5; Hebrews 3:5; 1 Peter 2:5). Peter is to be to the Church what the foundation is in regard to a house.
‘He is to be the principle of unity, of stability, and of increase. He is the principle of unity, since what is not joined to that foundation is no part of the Church; of stability, since it is the firmness of this foundation in virtue of which the Church remains unshaken by the storms which buffet her; of increase, since, if she grows, it is because new stones are laid on this foundation.’
