Matthew 16:18 - Exposition

And I say also ( I also say ) unto thee. As thou hast said unto me, "Thou art the Christ," so I say unto thee, etc. Thou art Peter ( πέτρος , Petrus ) , and upon this rock ( πέτρα , petra ) I will build my Church. In classical Greek, the distinction between πέτρα and πέτρος is well known—the former meaning "a rock," the latter "a piece of rock," or "a stone." But probably no such distinction is intended here, as there would be none in Aramaic. There is plainly a paronomasia here in the Greek; and, if our Lord spoke in Aramaic, the same play of words was exhibited in Kephas or kepha. When Jesus first called Peter to be a disciple, he imposed upon him the name Cephas, which the evangelist explains to be Peter ( John 1:42 ). The name was bestowed in anticipation of Peter's great confession: "Thou shalt be called." This preannouncement was here fulfilled and confirmed. Upon this passage chiefly the claims of the Roman Church, which for fifteen centuries have been the subject of acrimonious controversy, are founded. It is hence assumed that the Christian Church is founded upon Peter and his successors, and that these successors are the Bishops of Rome. The latter assertion may be left to the decision of history, which fails to prove that Peter was ever at Rome, or that he transmitted his supposed supremacy to the episcopate of that city. We have in this place to deal with the former assertion. Who or what is the rock on which Christ says that he will hereafter build his Church? French Romanists consider it a providential coincidence that they can translate the passage, "Je te disque, Tu es Pierre; et sur cette pierre je batirai," etc.; but persons outside the papal communion are not satisfied to hang their faith on a play of words. The early Fathers are by no means at one in their explanations of the paragraph. Living before Rome had laid claim to the tremendous privileges which it afterwards affected, they did not regard the statement in the light of later controversies; and even those who held Peter to be the rock would have indignantly repelled the assumptions which have been built on that interpretation. The apostolic Fathers seem to have mentioned the passage in none of their writings; and they could scarcely have failed to refer to it had they been aware of the tremendous issues dependent thereon. It was embodied in no Catholic Creed, and never made an article of the Christian faith. We may remark also that of the evangelists St. Matthew alone records the promise to Peter; Mark and Luke give his confession, which was the one point which Christ desired to elicit, and omit that which is considered to concern his privileges. This looks as though, in their view, the chief aim of the passage was not Peter, but Christ; not Peter's pre-eminence, but Christ's nature and office. At the same time, to deny all allusion to Peter in the "rock" is quite contrary to the genius of the language and to New Testament usage, and would not have been so pressed in modern times except for polemical purposes. Three views have been held on the interpretation of this passage.
