5 How then think we of the Lord Jesus Christ, that He lied? If it is a less evil to be deceived than to lie, dare we to say that He lies who we dare not to say is deceived? But He is neither deceived, nor does He lie; but in very deed as it is written (for of Him is it understood, of Him ought it to be understood), “Nothing false is said unto the King, and nothing false shall proceed out of His mouth.” If by King here he meant any man, let us prefer Christ the King, to a man-king.
But if, which is the truer understanding of it, it is Christ of whom he spoke, if I say, as is the truer understanding of it, it is Christ of whom he spoke (for to Him indeed nothing false is said, in that He is not deceived; from His Mouth nothing false proceeds, in that He does not lie); let us look how we are to understand the section of the Gospel, and let us not make the pitfall of a lie, as it were, on heavenly authority. But it is most absurd to be seeking to explain the truth, and to prepare a place for a lie.
What are you teaching me, I ask you, who art explaining this text to me, what would you teach me? I do not know whether you would dare to say, “Falsehood.” For if you should dare to say this, I turn away mine ears, and fasten them up with thorns, that if you should try to force your way, I might through their very pricking make away without the explanation of the Gospel. Tell me what you would wish to teach me, and you have resolved the difficulty. Tell me, I pray you; lo, here I am; mine ears are open, my heart is ready, teach me.
But I ask, what? I will not travel through many things. What are you going to teach me? Whatsoever learning you are about to bring forward, whatsoever strength to show in disputation, tell me this one thing only, one of two things I ask; are you going to teach me truth or falsehood? What do we suppose he will answer lest one depart; lest while he is open-mouthed and making an effort to bring out his words, I immediately leave him: what will he promise but truth? I am listening, standing, expecting, most earnestly expecting. See here, he who promised that he will teach me truth, insinuates falsehood concerning Christ. How then shall he teach truth, who would say that Christ is false? If Christ is false, can I hope that you will tell me the truth?
