"S. Clement of Alexandria says quite bluntly, after alluding to the Mysteries: "Even now I fear, as it is said, 'to cast the pearls before swine, lest they tread them underfoot, and turn and rend us.' For it is difficult to exhibit the really pure and transparent words respecting the true Light to swinish and untrained hearers." (Clarke's Ante-Nicene Christian Library, Vol. IV. Clement of Alexandria. Stromata, bk. I., ch. xii.)"
