How this man dies not of debt; and in what sense he can or cannot sin; and how neither he nor an angel deserves praise for their holiness, if it is impossible for them to sin.
Anselm. We ought not to question whether this man was about to die as a debt, as all other men do. 252For, if Adam would not have died had he not committed sin, much less should this man suffer death, in whom there can be no sin, for he is God.
Boso. Let me delay you a little on this point. For in either case it is no slight question with me whether it be said that he can sin or that he cannot. For if it be said that he cannot sin, it should seem hard to be believed. For to say a word concerning him, not as of one who never existed in the manner we have spoken hitherto, but as of one whom we know and whose deeds we know; who, I say, will deny that he could have done many things which we call sinful? For, to say nothing of other things, how shall we say that it was not possible for him to commit the sin of lying? For, when he says to the Jews, of his Father: “If I say that I know him not, I shall be a liar, like unto you,” and, in this sentence, makes use of the words: “I know him not,” who says that he could not have uttered these same four words, or expressing the same thing differently, have declared, “I know him not?” Now had he done so, he would have been a liar, as he himself says, and therefore a sinner. Therefore, since he could do this, he could sin.
Anselm. It is true that he could say this, and also that he could not sin.
Boso. How is that?
Anselm. All power follows the will. For, when I say that I can speak or walk, it is understood, if I choose. For, if the will be not implied as acting, there is no power, but only necessity. For, when I say that I can be dragged or bound unwillingly, this is not my power, but necessity and the power of another; since I am able to be dragged or bound in no other sense than this, that another can drag or bind 253me. So we can say of Christ, that he could lie, so long as we understand, if he chose to do so. And, since he could not lie unwillingly and could not wish to lie, none the less can it be said that he could not lie. So in this way it is both true that he could and could not lie.
Boso. Now let us return to our original inquiry with regard to that man, as if nothing were known of him. I say, then, if he were unable to sin, because, according to you, he could not wish to sin, he maintains holiness of necessity, and therefore he will not be holy from free will. What thanks, then, will he deserve for his holiness? For we are accustomed to say that God made man and angel capable of sinning on this account, that, when of their own free will they maintained holiness, though they might have abandoned it, they might deserve commendation and reward, which they would not have done had they been necessarily holy.
Anselm. Are not the angels worthy of praise, though unable to commit sin?
Boso. Doubtless they are, because they deserved this present inability to sin from the fact that when they could sin they refused to do so.
Anselm. What say you with respect to God, who cannot sin, and yet has not deserved this, by refusing to sin when he had the power? Must not he be praised for his holiness?
Boso. I should like to have you answer that question for me; for if I say that he deserves no praise, I know that I speak falsely. If, on the other hand, I say that he does deserve praise, I am afraid of invalidating my reasoning with respect to the angels.
Anselm. The angels are not to be praised for their 254holiness because they could sin, but because it is owing to themselves, in a certain sense, that now they cannot sin. And in this respect are they in a measure like God, who has, from himself, whatever he possesses. For a person is said to give a thing, who does not take it away when he can; and to do a thing is but the same as not to prevent it, when that is in one’s power. When, therefore, the angel could depart from holiness and yet did not, and could make himself unholy yet did not, we say with propriety that he conferred virtue upon himself and made himself holy. In this sense, therefore, has he holiness of himself (for the creature cannot have it of himself in any other way), and, therefore, should be praised for his holiness, because he is not holy of necessity but freely; for that is improperly called necessity which involves neither compulsion nor restraint. Wherefore, since whatever God has he has perfectly of himself, he is most of all to be praised for the good things which he possesses and maintains not by any necessity, but, as before said, by his own infinite unchangeableness. Therefore, likewise, that man who will be also God since every good thing which he possesses comes from himself, will be holy not of necessity but voluntarily, and, therefore, will deserve praise. For, though human nature will have what it has from the Divine nature, yet it will likewise have it from itself, since the two natures will be united in one person.
Boso. You have satisfied me on this point; and I see clearly that it is both true that he could not sin, and yet that he deserves praise for his holiness. But now I think the question arises, since God could make such a man, why he did not create angels and our 255first parents so as to be incapable of sin, and yet praiseworthy for their holiness?
Anselm. Do you know what you are saying?
Boso. I think I understand, and it is therefore I ask why he did not make them so.
Anselm. Because it was neither possible nor right for any one of them to be the same with God, as we say that man was. And if you ask why he did not bring the three persons, or at least the Word, into unity with men at that time, I answer: Because reason did not at all demand any such thing then, but wholly forbade it, for God does nothing without reason.
Boso. I blush to have asked the question. Go on with what you have to say.
Anselm. We must conclude, then, that he should not be subject to death, inasmuch as he will not be a sinner.
Boso. I must agree with you.
