The pinnacle of the gospel drama may be Jesus’ dramatic statement, “You are Petros and on this petra I will build my church.” The saying seems to contain an obvious Greek wordplay, perhaps indicating that Jesus spoke in Greek. However, it is possible that “Petros…petra” is a Hebrew wordplay.
The recognition that the synoptic gospels are derived from a Semitic source or sources seems essential to any productive methodology of interpretation. Often, unless one translates the Greek texts of the synoptic gospels to Hebrew, one cannot fully understand their meaning. For example, when the Beatitudes are translated to Hebrew, one sees that they are not eschatological, but, like the beatitudes of the Hebrew Scriptures, speak of rewards in the here and now.
The Greek words πέτρος (petros) and πέτρα (petra) employed by Jesus in Matthew 16:18 make a nice wordplay. This Greek wordplay appears to be a direct contradiction to the assumption that Jesus taught in Hebrew. If Jesus delivered this saying in Hebrew, as many scholars in Israel assume, how could it have contained a Greek wordplay?
Some scholars have suggested an Aramaic background to Jesus’ saying. Joseph A. Fitzmyer, Professor Emeritus of The Catholic University of America in Washington, D.C., and one of the world’s most distinguished New Testament scholars, suggests that Jesus employed an Aramaic wordplay (Kepha-kepha) in his response to Peter’s declaration. However, Fitzmyer acknowledges a difficulty: he wonders why the Matthean Jesus did not say, “On this petros I will build….” This difficulty is a product of Fitzmyer’s Aramaic reconstruction. He has been forced in Aramaic to reconstruct Jesus’ wordplay using only one word; therefore, he is unable to preserve the wordplay reflected in Greek, a play on two different words.

Wilson (Cambridge, UK: Cambridge University Press, 1979), pp. 121-132. Fitzmyer suggests that in Aramaic Jesus said: antah hu Kepha we’al kepha den ebneh… (You are Kepha [Cephas], and on this kepha [rock] I will build…). ↩
-  Substituting the Greek masculine petros for the Greek feminine petra, the reading of all Greek manuscripts. See Fitzmyer, ibid., pp. 130-131: “The problem that confronts one is to explain why there is in the Matthean passage a translation of the Aramaic substratum, which is claimed to have the same word kepha twice, by two Greek words, πέτρος and πέτρα… If the underlying Aramaic of Matt. xvi.18 had kepha twice, then we should expect σὺ εἶ Πέτρος, καὶ ἐπὶ τούτῳ τῷ πέτρῳ οἰκοδομήσω….” Cf. Fitzmyer’s recent comments in response to a magazine reader’s letter (“Queries & Comments,”Biblical Archaeology Review 19.3 , 70). For Fitzmyer’s Aramaic reconstruction to be correct, the Greek text should read, “on this petros I will build….” ↩
-  The word כֵּפָא (kepha). The only difference between Kepha and kepha in Fitzmyer’s reconstruction is the capitalization of the former. This distinction, however, does not exist in Aramaic, since in Aramaic there are no capital letters. ↩
