QUESTION 24
THE BOOK OF LIFE (In Three Articles) We now consider the book of life; concerning which there are three points of inquiry: (1) What is the book of life? (2) Of what life is it the book? (3) Whether anyone can be blotted out of the book of life? _______________________ FIRST ARTICLE [I, Q. 24, Art. 1] Whether the Book of Life Is the Same As Predestination? Objection 1: It seems that the book of life is not the same thing as predestination. For it is said, "All things are the book of life" (Ecclus. 4:32)--i.e. the Old and New Testament according to a gloss. This, however, is not predestination. Therefore the book of life is not predestination. Obj. 2: Further, Augustine says (De Civ. Dei xx, 14) that "the book of life is a certain divine energy, by which it happens that to each one his good or evil works are recalled to memory." But divine energy belongs seemingly, not to predestination, but rather to divine power. Therefore the book of life is not the same thing as predestination. Obj. 3: Further, reprobation is opposed to predestination. So, if the book of life were the same as predestination, there should also be a book of death, as there is a book of life. _On the contrary,_ It is said in a gloss upon Ps. 68:29, "Let them be blotted out of the book of the living," "This book is the knowledge of God, by which He hath predestined to life those whom He foreknew."
_I answer that,_ The book of life is in God taken in a metaphorical sense, according to a comparison with human affairs. For it is usual among men that they who are chosen for any office should be inscribed in a book; as, for instance, soldiers, or counsellors, who formerly were called "conscript" fathers. Now it is clear from the preceding (Q. 23, A. 4) that all the predestined are chosen by God to possess eternal life. This conscription, therefore, of the predestined is called the book of life. A thing is said metaphorically to be written upon the mind of anyone when it is firmly held in the memory, according to Prov. 3:3: "Forget not My Law, and let thy heart keep My commandments," and further on, "Write them in the tables of thy heart." For things are written down in material books to help the memory. Whence, the knowledge of God, by which He firmly remembers that He has predestined some to eternal life, is called the book of life. For as the writing in a book is the sign of things to be done, so the knowledge of God is a sign in Him of those who are to be brought to eternal life, according to 2 Tim. 11:19: "The sure foundation of God standeth firm, having this seal; the Lord knoweth who are His."
SECOND ARTICLE [I, Q. 24, Art. 2] Whether the Book of Life Regards Only the Life of Glory of the Predestined? Objection 1: It seems that the book of life does not only regard the life of glory of the predestined. For the book of life is the knowledge of life. But God, through His own life, knows all other life. Therefore the book of life is so called in regard to divine life; and not only in regard to the life of the predestined. Obj. 2: Further, as the life of glory comes from God, so also does the life of nature. Therefore, if the knowledge of the life of glory is called the book of life; so also should the knowledge of the life of nature be so called. Obj. 3: Further, some are chosen to the life of grace who are not chosen to the life of glory; as it is clear from what is said: "Have not I chosen you twelve, and one of you is a devil?" (John 6:71). But the book of life is the inscription of the divine election, as stated above (A. 1). Therefore it applies also to the life of grace. _On the contrary,_ The book of life is the knowledge of predestination, as stated above (ibid.). But predestination does not regard the life of grace, except so far as it is directed to glory; for those are not predestined who have grace and yet fail to obtain glory. The book of life altogether is only so called in regard to the life of glory.
THIRD ARTICLE [I, Q. 24, Art. 3] Whether Anyone May Be Blotted Out of the Book of Life? Objection 1: It seems that no one may be blotted out of the book of life. For Augustine says (De Civ. Dei xx, 15): "God's foreknowledge, which cannot be deceived, is the book of life." But nothing can be taken away from the foreknowledge of God, nor from predestination. Therefore neither can anyone be blotted out from the book of life. Obj. 2: Further, whatever is in a thing is in it according to the disposition of that thing. But the book of life is something eternal and immutable. Therefore whatsoever is written therein, is there not in a temporary way, but immovably, and indelibly. Obj. 3: Further, blotting out is the contrary to inscription. But nobody can be written a second time in the book of life. Neither therefore can he be blotted out. _On the contrary,_ It is said, "Let them be blotted out from the book of the living" (Ps. 68:29).
_I answer that,_ Some have said that none could be blotted out of the book of life as a matter of fact, but only in the opinion of men. For it is customary in the Scriptures to say that something is done when it becomes known. Thus some are said to be written in the book of life, inasmuch as men think they are written therein, on account of the present righteousness they see in them; but when it becomes evident, either in this world or in the next, that they have fallen from that state of righteousness, they are then said to be blotted out. And thus a gloss explains the passage: "Let them be blotted out of the book of the living." But because not to be blotted out of the book of life is placed among the rewards of the just, according to the text, "He that shall overcome, shall thus be clothed in white garments, and I will not blot his name out of the book of life" (Apoc.
3:5) (and what is promised to holy men, is not merely something in the opinion of men), it can therefore be said that to be blotted out, and not blotted out, of the book of life is not only to be referred to the opinion of man, but to the reality of the fact. For the book of life is the inscription of those ordained to eternal life, to which one is directed from two sources; namely, from predestination, which direction never fails, and from grace; for whoever has grace, by this very fact becomes fitted for eternal life. This direction fails sometimes; because some are directed by possessing grace, to obtain eternal life, yet they fail to obtain it through mortal sin. Therefore those who are ordained to possess eternal life through divine predestination are written down in the book of life simply, because they are written therein to have eternal life in reality; such are never blotted out from the book of life. Those, however, who are ordained to eternal life, not through divine predestination, but through grace, are said to be written in the book of life not simply, but relatively, for they are written therein not to have eternal life in itself, but in its cause only. Yet though these latter can be said to be blotted out of the book of life, this blotting out must not be referred to God, as if God foreknew a thing, and afterwards knew it not; but to the thing known, namely, because God knows one is first ordained to eternal life, and afterwards not ordained when he falls from grace.
