4. But perhaps we ought to call Peter and John ignorant, both of whom could say of themselves, “though I be rude in speech, yet not in knowledge.” Was John a mere fisherman, rude and untaught? If so, whence did he get the words “In the beginning was the word, and the word was with God and the word was God.” Logos in Greek has many meanings. It signifies word and reason and reckoning and the cause of individual things by which those which are subsist. All of which things we rightly predicate of Christ. This truth Plato with all his learning did not know, of this Demosthenes with all his eloquence was ignorant. “I will destroy,” it is said, “the wisdom of the wise, and will bring to nothing the understanding of the prudent.” The true wisdom must destroy the false, and, although the foolishness of preaching is inseparable from the Cross, Paul speaks “wisdom among them that are perfect, yet not the wisdom of this world, nor of the princes of this world that come to nought,” but he speaks “the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world.” God’s wisdom is Christ, for Christ, we are told, is “the power of God and the wisdom of God.” He is the wisdom which is hidden in a mystery, of which also we read in the heading of the ninth psalm “for the hidden things of the son.” In Him are hidden all the treasures of wisdom and knowledge. He also who was hidden in a mystery is the same that was foreordained before the world. Now it was in the Law and in the Prophets that he was foreordained and prefigured. For this reason too the prophets were called seers, because they saw Him whom others did not see. Abraham saw His day and was glad. The heavens which were sealed to a rebellious people were opened to Ezekiel. “Open thou mine eyes,” saith David, “that I may behold wonderful things out of thy Law.” For “the law is spiritual” and a revelation is needed to enable us to comprehend it and, when God uncovers His face, to behold His glory.
