As an example of his mode of interpretation, and turning the plain sense of words from their proper meaning to proofs that Christ was God in the flesh, we will give his explanation of the prophecy of Isaiah, which relates to his birth from a virgin: "Therefore, the Lord himself shall give you a sign: Behold, a virgin shall conceive and bear a son; and ye shall call his name Emmanuel. Butter and honey shall he eat: before he knows or chooses out things that are evil, He shall exchange them for what is good; for before the child knows good or evil, He shall not consent to evil, that he may choose that which is good." Here follow the comments: "Carefully, then, has the holy Ghost pointed out, by what has been said--His birth from a virgin and His essence, for he is God (for the name of Emmanuel indicates this). And he shows that he is a man when he says, 'Butter and honey shall he eat;' and in that he terms him a child also, in saying, 'before he knows good from evil;' for these are all tokens of a human infant. But that he 'will not consent to evil that he may choose what is good,' this is proper to God; that by the fact, that He shall eat butter and honey, we would understand that He is a mere man only--nor on the other hand from the name Emmanuel, should suspect him to be Christ without flesh." (Book ill. ch. 21, sec. 4.) That is, Christ is in the flesh, because he is to eat butter and honey; and he is God, because he knows how to distinguish between good and evil; and as a consequence, the divine and human nature are united in his person, and he is the incarnate God. We have shown in another part of this work that the prophecy of Isaiah had nothing to do with a future Christ, but was meant as a measure of time, governed by the period of gestation.
