There are three sacred languages: Hebrew, Greek, and Latin, which are the most outstanding in the entire world. For in these three languages, the case of the Lord was written upon the cross by Pontius Pilate. For this reason, and on account of the obscurity of Sacred Scriptures, the understanding of these three languages is necessary so that you may reference one of the others if an expression in one of the languages presents some doubt to your mind about the meaning of a word or its interpretation.
