Matt 16:18 isQ: in the verse why is Peter referred to as Petros then as Petra? Shouldn’t it go “thou art Petros and on Petros I will build my Church”?
And I tell you, you are Peter, and on this rock I will build my church, and the gates of Hades will not prevail against it.
The Holy Bible : New Revised Standard Version (Nashville: Thomas Nelson Publishers, 1989), Mt 16:18.
Here Peter is PETROS and rock is PETRA. Thus Paul wrote thou art Petros and on this PETRA I will build my Church. The Greek is correct since PETRA (rock) is feminine.κἀγὼ δέ σοι λέγω ὅτι σὺ εἶ Πέτρος, καὶ ἐπὶ ταύτῃ τῇ** πέτρᾳ **οἰκοδομήσω μου τὴν ἐκκλησίαν καὶ πύλαι ᾅδου οὐ κατισχύσουσιν αὐτῆς.
Barbara Aland et al., The Greek New Testament (4th ed.; Federal Republic of Germany: United Bible Societies, 1993, c1979),
Again I hope this is clear.
Basically PETROS is masculine, and PETRA is feminine always.
