If you dont believe in the divine, God-breathed inspiration of Scripture and Divine Providence, then theres nothing to say.
And I also say to you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overpower it.
In the language Jesus spoke it would have been.
And I also say to you that you are Cephas, and on this Cephas I will build my church, and the gates of Hades will not overpower it.
Since it was written in Greek it was changed to petros but that mistake has been fixed as it is now in English and Jesus plainly said rock, Peter is the rock in English amd also in Aramaic.
