Now, in this precept by which we are forbidden to give what is holy to the dogs, and to cast our pearls before swine, we must carefully require what is meant by holy, what by pearls, what by dogs, what by swine. A holy thing is something which it is impious to violate and to corrupt; and the very attempt and wish to commit that crime is held to be criminal, although that holy thing should remain in its nature inviolable and incorruptible. By pearls, again, are meant whatever spiritual things we ought to set a high value upon, both because they lie hid in a secret place, are as it were brought up out of the deep, and are found in wrappings of allegory, as it were in shells that have been opened. We may therefore legitimately understand that one and the same thing may be called both holy and a pearl: but it gets the name of holy for this reason, that it ought not to be corrupted; of a pearl for this reason, that it ought not to be despised. Every one, however, endeavours to corrupt what he does not wish to remain uninjured: but he despises what he thinks worthless, and reckons to be as it were beneath himself; and therefore whatever is despised is said to be trampled on. And hence, inasmuch as dogs spring at a thing in order to tear it in pieces, and do not allow what they are tearing in pieces to remain in its original condition, "Give not," says He, "that which is holy unto the dogs:" for although it cannot be torn in pieces and corrupted, and remains unharmed and inviolable, yet we must think of what is the wish of those parties who bitterly and in a most unfriendly spirit resist, and, as far as in them lies, endeavour, if it were possible, to destroy the truth. But swine, although they do not, like dogs, fall upon an object with their teeth, yet by recklessly trampling on it defile it: "Do not therefore cast your pearls before swine, lest they trample them under their feet, and turn again and rend you." We may therefore not unsuitably understand dogs as used to designate the assailants of the truth, swine the despisers of it.
