But in the Greek text the word for Peter is Petros, and for slone, petra. They are not the same.

There is no value in pointing out the differences of form in this word according to the Latin or Greek languages, in which they are accommodated to the masculine for Peter as a man, and to the feminine for stone. Our Lord spoke in Aramaic, in which the form is the same in both cases, simply Kepha.
