You appeal to the Aramaic. I know nothing of that, nor of the Latin, nor of the Greek. I accept the Bible in its English form, in which the two words are Peter and rock, and nothing whatever alike.

The Catholic Answers

How can you appeal to the English form, if the English translation does not adequately express what Christ meant? Surely you want the exact teaching of Christ! The English version is not an infallible rendering, nor does anyone versed in these matters claim that the English language fully expresses the sense of the originals. But apparently you are content to be without the truth, if it is not to be discovered superficially by the reading of your talismanic English version.
