BIBLE COMMENTARY ON "ROCK" OF MATTHEW 16:18
D.A. Carson (Protestant Evangelical) --
"Although it is true that petros and petra can mean 'stone' and 'rock' respectively in earlier Greek, the distinction is largely confined to poetry. Moreover, the underlying Aramaic is in this case unquestionable; and most probably kepha was used in both clauses ('you are kepha' and 'on this kepha'), since the word was used both for a name and for a 'rock.' The Peshitta (written in Syriac, a language cognate with Aramaic) makes no distinction between the words in the two clauses. The Greek makes the distinction between petros and petra simply because it is trying to preserve the pun, and in Greek the feminine petra could not very well serve as a masculine name." (Carson, The Expositor's Bible Commentary [Zondervan, 1984], volume 8, page 368, as cited in Butler/Dahlgren/Hess, page 17-18)
"The word Peter petros, meaning 'rock,' (Gk 4377) is masculine, and in Jesus' follow-up statement he uses the feminine word petra (Gk 4376). On the basis of this change, many have attempted to avoid identifying Peter as the rock on which Jesus builds his church yet if it were not for Protestant reactions against extremes of Roman Catholic interpretations, it is doubtful whether many would have taken 'rock' to be anything or anyone other than Peter." (Carson, Zondervan NIV Bible Commentary [Zondervan, 1994], volume 2, page 78, as cited in Butler/Dahlgren/Hess, page 18)
R.T. France (Anglican/Protestant Evangelical) --
"The name Peter means 'Rock', and Jesus played on this meaning to designate Peter as the foundation of the new people of God. His leadership would involve the authority of the steward, whose keys symbolized his responsibility to regulate the affairs of the household. Peter would exercise his leadership by his authority to declare what is and is not permissible in the kingdom of heaven (to bind and to loose have this meaning in rabbinic writings)....It is sometimes suggested that because the word for 'rock' (petra) differs from the name Petros, the 'rock' referred to is not Peter himself but the confession he has just made of Jesus as Messiah. In Aramaic, however, the same term kefa would appear in both places; the change in Greek is due to the fact that petra, the normal word for rock, is feminine in gender, and therefore not suitable as a name for Simon! The echo of Peter's name remains obvious, even in Greek; he is the rock, in the sense outlined above." (France, New Bible Commentary with consulting editors Carson, France, Motyer, Wenham [Intervarsity Press, 1994], page 925, 926)
Oscar Cullmann (Lutheran) from Kittel's Greek Standard Theological Dictionary of the New Testament --
"The obvious pun which has made its way into the Gk. text as well suggests a material identity between petra and petros, the more so as it is impossible to differentiate strictly between the meanings of the two words. On the other hand, only the fairly assured Aramaic original of the saying enables us to assert with confidence the formal and material identity between petra and petros: petra = Kepha = petros....Since Peter, the rock of the Church, is thus given by Christ Himself, the master of the house (Is. 22:22; Rev. 3:7), the keys of the kingdom of heaven, he is the human mediator of the resurrection, and he has the task of admitting the people of God into the kingdom of the resurrection...The idea of the Reformers that He is referring to the faith of Peter is quite inconceivable in view of the probably different setting of the story...For there is no reference here to the faith of Peter. Rather, the parallelism of 'thou art Rock' and 'on this rock I will build' shows that the second rock can only be the same as the first. It is thus evident that Jesus is referring to Peter, to whom He has given the name Rock. He appoints Peter, the impulsive, enthusiastic, but not persevering man in the circle, to be the foundation of His ecclesia. To this extent Roman Catholic exegesis is right and all Protestant attempts to evade this interpretation are to be rejected." (Cullmann, article on "Rock" (petros, petra) trans. and ed. by Geoffrey W. Bromiley, Theological Dictionary of the New Testament [Eerdmans Publishing, 1968], volume 6, page 98, 107, 108)
Herman Ridderbos (Protestant Evangelical) --
"It is well known that the Greek word (petra) translated 'rock' here is different from the proper name Peter. The slight difference between them has no special importance, however. The most likely explanation for the change from petros ('Peter') to petra is that petra was the normal word for 'rock.' Because the feminine ending of this noun made it unsuitable as a man's name, however, Simon was not called petra but petros. The word petros was not an exact synonym of petra; it literally meant 'stone.' Jesus therefore had to switch to the word petra when He turned from Peter's name to what it meant for the Church. There is no good reason to think that Jesus switched from petros to petra to show that He was not speaking of the man Peter but of his confession as the foundation of the Church. The words 'on this rock [petra]' indeed refer to Peter. Because of the revelation that he had received and the confession that it motivated in him, Peter was appointed by Jesus to lay the foundation of the future church." (Ridderbos, Bible Student's Commentary: Matthew [Zondervan, 1987], page 303 as cited in Butler/Dahlgren/Hess, page 35-36)
Craig Blomberg (Protestant Evangelical) --
"Acknowledging Jesus as The Christ illustrates the appropriateness of Simon's nickname 'Peter' (Petros=rock). This is not the first time Simon has been called Peter (cf. John 1:42 [wherein he is called Cephas]), but it is certainly the most famous. Jesus' declaration, 'You are Peter,' parallels Peter's confession, 'You are the Christ,' as if to say, 'Since you can tell me who I am, I will tell you who you are.' The expression 'this rock' almost certainly refers to Peter, following immediately after his name, just as the words following 'the Christ' in v. 16 applied to Jesus. The play on words in the Greek between Peter's name (Petros) and the word 'rock' (petra) makes sense only if Peter is the rock and if Jesus is about to explain the significance of this identification." (Blomberg, The New American Commentary: Matthew [Broadman, 1992], page 251-252, as cited in Butler/Dahlgren/Hess, page 31-32)
William F. Albright and C.S. Mann (from The Anchor Bible series) --
"Rock (Aram. Kepha). This is not a name, but an appellation and a play on words. There is no evidence of Peter or Kephas as a name before Christian times. On building on a rock, or from a rock, cf. Isa 51:1ff; Matt 7:24f. Peter as Rock will be the foundation of the future community (cf. I will build). Jesus, not quoting the OT, here uses Aramaic, not Hebrew, and so uses the only Aramaic word which would serve his purpose. In view of the background of vs. 19 (see below), one must dismiss as confessional interpretation any attempt to see this rock as meaning the faith, or the Messianic confession, of Peter. To deny the pre-eminent position of Peter among the disciples or in the early Christian community is a denial of the evidence. Cf. in this gospel 10:2; 14:28-31; 15:15. The interest in Peter's failures and vacillations does not detract from this pre-eminence; rather, it emphasizes it. Had Peter been a lesser figure his behavior would have been of far less consequence (cf. Gal 2:11ff)." (Albright/Mann, The Anchor Bible: Matthew [Doubleday, 1971], page 195)
Craig S. Keener (Protestant Evangelical) --
"'You are Peter,' Jesus says (16:18), paralleling Peter's 'You are the Christ' (16:16). He then plays on Simon's nickname, 'Peter,' which is roughly the English 'Rocky': Peter is 'rocky,' and on this rock Jesus would build his church (16:18)....Protestants...have sometimes argued that Peter's name in Greek (petros) differs from the Greek term for rock used here (petra)....But by Jesus' day the terms were usually interchangeable, and the original Aramaic form of Peter's nickname that Jesus probably used (kephas) means simply 'rock.' Further, Jesus does not say, 'You are Peter, but on this rock I will build my church'....the copulative kai almost always means 'and'.... Jesus' teaching is the ultimate foundation for disciples (7:24-27; cf. 1 Cor 3:11), but here Peter functions as the foundation rock as the apostles and prophets do in Ephesians 2:20-21....Jesus does not simply assign this role arbitrarily to Peter, however; Peter is the 'rock' because he is the one who confessed Jesus as the Christ in this context (16:15-16)...." (Keener, A Commentary on the Gospel of Matthew [Eerdmans, 1999], page 426-427)
Francis Wright Beare (Presbyterian/Reformed) --
"The play on words -- 'Peter', this 'rock' -- requires a change in Greek from petros (properly, 'stone') to petra. In Aramaic, the two words would be identical -- Kepha the name given to Peter, transliterated into Greek as Kephas (Gal. 2:9), and kepha, 'rock'. The symbol itself is Hebraic: Abraham is the 'rock' from which Israel was hewn, and in a rabbinic midrash, God finds in him a rock on which he can base and build the world..." (Beare, The Gospel According to Matthew [Harper and Row, 1981], page 355)
Eduard Schweizer (Presbyterian/Reformed) --
"The 'rock' is Peter himself, not his confession. Only on this interpretation does the pun make sense." (Schweizer, The Good News According to Matthew [John Knox Press, 1975], page 341)
Ivor H. Jones (Methodist) --
"...in 16.18 Peter is the rock on which the new community could be built, as Abraham was described in rabbinic writings as the rock on which God could erect a new world to replace the old....The arguments have raged across the centuries over the phrase 'on this rock' : does it mean on Peter, or on Peter's confession? But the text is clear: Peter was divinely inspired and this was the reason for his new function and the basis of his authorization. His function was to provide for Jesus Christ the beginnings of a stronghold, a people of God, to stand against all the powers of evil and death...They are God's people, the church...as the church they represent God's sovereign power over evil (18.18b) and rely upon a new kind of divine authorization...This authorization is given to Peter; so Peter is not only a stronghold against evil; he also is responsible for giving the community shape and direction." (Jones, The Gospel of Matthew [London: Epworth Press, 1994], page 99)
M. Eugene Boring (Disciples of Christ) --
"16:18, Peter as Rock. Peter is the foundation rock on which Jesus builds the new community. The name 'Peter' means 'stone' or 'rock' (Aramaic Kepha Cepha; Greek petros).... There are no documented instances of anyone's ever being named 'rock' in Aramaic or Greek prior to Simon. Thus English translations should render the word 'stone' or 'rock,' not 'Peter,' which gives the false impression that the word represented a common name and causes the contemporary reader to miss the word play of the passage: 'You are Rock, and on this rock I will build my church.' Peter is here pictured as the foundation of the church....On the basis of Isa 51:1-2 (cf. Matt 3:9), some scholars have seen Peter as here paralleled to Abraham; just as Abram stood at the beginning of the people of God, had his name changed, and was called a rock, so also Peter stands at the beginning of the new people of God and receives the Abrahamic name 'rock' to signify this." (The New Interpreter's Bible [Abingdon Press, 1995], volume 8, page 345)
Thomas G. Long (Presbyterian/Reformed) --
"Since, in the original Greek, Petros and petra both mean 'rock,' it is easy to spot this statement as a pun, a play on words: 'Your name is "Rock," and on this "rock" I will build my church.' Jesus' meaning is plain: Peter is the rock, the foundation, upon which he is going to erect his church...Jesus spoke Aramaic, however, not Greek. In Aramaic, the words for 'Peter' and 'rock' are the same (Kepha)...the most plausible interpretation of the passage is that Jesus is, indeed, pointing to Peter as the foundation stone, the principal leader, of this new people of God...there is much evidence that he also played a primary leadership role in the early Christian church....For the church, the new people of God, Peter was, indeed, the 'rock,' corresponding to Abraham of old, who was 'the rock from which you were hewn' (Isa. 51:1)." (Long, Matthew [Westminster John Knox Press, 1997], page 185, 186)
Richard B. Gardner (Brethren/Mennonite) --
"The key question here is whether the rock foundation of the church is Peter himself, or something to be distinguished from Peter. If the latter, Jesus could be speaking of Peter's faith, or of the revelation Peter received. It is more likely, however, that the rock on which Jesus promises to build the church is in fact Peter himself, Peter the first disciple (cf. 4:18; 10:2), who represents the whole group of disciples from which the church will be formed. At least four considerations support this view...." (Gardner, Believers Church Bible Commentary: Matthew [Herald Press, 1991], 247)
