10. But lest this difficulty perhaps should be sup­posed to exist only in the language of the prophets, seeing the prophetic style is allowed by all to abound in figures and enigmas, what do we find when we come to the Gospels? Is there not hidden there also an inner, namely a divine sense, which is re­vealed by that grace alone which he had received who said, “But we have the mind of Christ, that we might know the things freely given to us by God. Which things also we speak, not in the words which man’s wisdom teaches, but which the Spirit teach­eth?” And if one now were to read the revelations which were made to John, how amazed would he not be that there should be contained within them so great an amount of hidden, ineffable mysteries, in which it is clearly understood, even by those who cannot comprehend what is concealed, that some­thing certainly is concealed. And yet are not the Epistles of the Apostles, which seem to some to be plainer, filled with meanings so profound, that by means of them, as by some small receptacle, the clearness of incalculable light appears to be poured into those who are capable of understanding the meaning of divine wisdom? And therefore, because this is the case, and because there are many who go wrong in this life, I do not consider that it is easy to pronounce, without danger, that anyone knows or understands those things, which, in order to be opened up, need the key of knowledge; which key, the Saviour declared, lay with those who were skilled in the law. And here, although it is a digression, I think we should inquire of those who assert that be­fore the advent of the Saviour there was no truth among those who were engaged in the study of the law, how it could be said by our Lord Jesus Christ that the keys of knowledge were with them, who had the books of the prophets and of the law in their hands. For thus did He speak: “Woe unto you, ye teachers of the law, who have taken away the key of knowledge: ye entered not in yourselves, and them who wished to enter in ye hindered.”
