[I-II.q.89.a.2.arg.1] It would seem that venial sins are unsuitably designated as "wood," "hay," and "stubble." Because wood hay and stubble are said (1 Corinthians 3:12) to be built on a spiritual foundation. Now venial sins are something outside a spiritual foundation, even as false opinions are outside the pale of science. Therefore, venial sins are not suitably designated as wood, hay and stubble.

[I-II.q.89.a.2.arg.2] Further, he who builds wood, hay and stubble, "shall be saved yet so as by fire" (1 Corinthians 3:15). But sometimes the man who commits a venial sin, will not be saved, even by fire, e.g. when a man dies in mortal sin to which venial sins are attached. Therefore, venial sins are unsuitably designated by wood, hay, and stubble.

[I-II.q.89.a.2.arg.3] Further, according to the Apostle (1 Corinthians 3:12) those who build "gold, silver, precious stones," i.e. love of God and our neighbor, and good works, are others from those who build wood, hay, and stubble. But those even who love God and their neighbor, and do good works, commit venial sins: for it is written (1 John 1:8): "If we say that we have no sin, we deceive ourselves." Therefore venial sins are not suitably designated by these three.

[I-II.q.89.a.2.arg.4] Further, there are many more than three differences and degrees of venial sins. Therefore they are unsuitably comprised under these three.

[I-II.q.89.a.2.sc] The Apostle says (1 Corinthians 3:15) that the man who builds up wood, hay and stubble, "shall be saved yet so as by fire," so that he will suffer punishment, but not everlasting. Now the debt of temporal punishment belongs properly to venial sin, as stated above (Question 87, Article 5). Therefore these three signify venial sins.

[I-II.q.89.a.2.co] Some have understood the "foundation" to be dead faith, upon which some build good works, signified by gold, silver, and precious stones, while others build mortal sins, which according to them are designated by wood, hay and stubble. But Augustine disapproves of this explanation (De Fide et Oper. xv), because, as the Apostle says (Galatians 5:21), he who does the works of the flesh, "shall not obtain the kingdom of God," which signifies to be saved; whereas the Apostle says that he who builds wood, hay, and stubble "shall be saved yet so as by fire." Consequently wood, hay, stubble cannot be understood to denote mortal sins.

Others say that wood, hay, stubble designate good works, which are indeed built upon the spiritual edifice, but are mixed with venial sins: as, when a man is charged with the care of a family, which is a good thing, excessive love of his wife or of his children or of his possessions insinuates itself into his life, under God however, so that, to wit, for the sake of these things he would be unwilling to do anything in opposition to God. But neither does this seem to be reasonable. For it is evident that all good works are referred to the love of God, and one's neighbor, wherefore they are designated by "gold," "silver," and "precious stones," and consequently not by "wood," "hay," and "stubble."

We must therefore say that the very venial sins that insinuate themselves into those who have a care for earthly things, are designated by wood, hay, and stubble. For just as these are stored in a house, without belonging to the substance of the house, and can be burnt, while the house is saved, so also venial sins are multiplied in a man, while the spiritual edifice remains, and for them, man suffers fire, either of temporal trials in this life, or of purgatory after this life, and yet he is saved for ever.

[I-II.q.89.a.2.ad.1] Venial sins are not said to be built upon the spiritual foundation, as though they were laid directly upon it, but because they are laid beside it; in the same sense as it is written (Psalm 136:1): "Upon the waters of Babylon," i.e. "beside the waters": because venial sins do not destroy the edifice.

[I-II.q.89.a.2.ad.2] It is not said that everyone who builds wood, hay and stubble, shall be saved as by fire, but only those who build "upon" the "foundation." And this foundation is not dead faith, as some have esteemed, but faith quickened by charity, according to Ephesians 3:17: "Rooted and founded in charity." Accordingly, he that dies in mortal sin with venial sins, has indeed wood, hay, and stubble, but not built upon the spiritual edifice; and consequently he will not be saved so as by fire.

[I-II.q.89.a.2.ad.3] Although those who are withdrawn from the care of temporal things, sin venially sometimes, yet they commit but slight venial sins, and in most cases they are cleansed by the fervor of charity: wherefore they do not build up venial sins, because these do not remain long in them. But the venial sins of those who are busy about earthly remain longer, because they are unable to have such frequent recourse to the fervor of charity in order to remove them.

[I-II.q.89.a.2.ad.4] As the Philosopher says (De Coelo i, text. 2), "all things are comprised under three, the beginning, the middle, the end." Accordingly all degrees of venial sins are reduced to three, viz. to "wood," which remains longer in the fire; "stubble," which is burnt up at once; and "hay," which is between these two: because venial sins are removed by fire, quickly or slowly, according as man is more or less attached to them.

[I-II.q.89.a.3.arg.1] It would seem that man could commit a venial sin in the state of innocence. Because on 1 Timothy 2:14, "Adam was not seduced," a gloss says: "Having had no experience of God's severity, it was possible for him to be so mistaken as to think that what he had done was a venial sin." But he would not have thought this unless he could have committed a venial sin. Therefore he could commit a venial sin without sinning mortally.

[I-II.q.89.a.3.arg.2] Further Augustine says (Gen. ad lit. xi, 5): "We must not suppose that the tempter would have overcome man, unless first of all there had arisen in man's soul a movement of vainglory which should have been checked." Now the vainglory which preceded man's defeat, which was accomplished through his falling into mortal sin, could be nothing more than a venial sin. In like manner, Augustine says (Gen. ad lit. xi, 5) that "man was allured by a certain desire of making the experiment, when he saw that the woman did not die when she had taken the forbidden fruit." Again there seems to have been a certain movement of unbelief in Eve, since she doubted what the Lord had said, as appears from her saying (Genesis 3:3): "Lest perhaps we die." Now these apparently were venial sins. Therefore man could commit a venial sin before he committed a mortal sin.

[I-II.q.89.a.3.arg.3] Further, mortal sin is more opposed to the integrity of the original state, than venial sin is. Now man could sin mortally notwithstanding the integrity of the original state. Therefore he could also sin venially.

[I-II.q.89.a.3.sc] Every sin deserves some punishment. But nothing penal was possible in the state of innocence, as Augustine declares (De Civ. Dei xiv, 10). Therefore he could commit a sin that would not deprive him of that state of integrity. But venial sin does not change man's state. Therefore he could not sin venially.

[I-II.q.89.a.3.co] It is generally admitted that man could not commit a venial sin in the state of innocence. This, however, is not to be understood as though on account of the perfection of his state, the sin which is venial for us would have been mortal for him, if he had committed it. Because the dignity of a person is circumstance that aggravates a sin, but it does not transfer it to another species, unless there be an additional deformity by reason of disobedience, or vow or the like, which does not apply to the question in point. Consequently what is venial in itself could not be changed into mortal by reason of the excellence of the original state. We must therefore understand this to mean that he could not sin venially, because it was impossible for him to commit a sin which was venial in itself, before losing the integrity of the original state by sinning mortally.

The reason for this is because venial sin occurs in us, either through the imperfection of the act, as in the case of sudden movements, in a genus of mortal sin or through some inordinateness in respect of things referred to the end, the due order of the end being safeguarded. Now each of these happens on account of some defect of order, by reason of the lower powers not being checked by the higher. Because the sudden rising of a movement of the sensuality in us is due to the sensuality not being perfectly subject to reason: and the sudden rising of a movement of reason itself is due, in us, to the fact that the execution of the act of reason is not subject to the act of deliberation which proceeds from a higher good, as stated above (Question 74, Article 10); and that the human mind be out of order as regards things directed to the end, the due order of the end being safeguarded, is due to the fact that the things referred to the end are not infallibly directed under the end, which holds the highest place, being the beginning, as it were, in matters concerning the appetite, as stated above (10, A1,2, ad 3; 72, 5). Now, in the state of innocence, as stated in the I, 95, 1, there was an unerring stability of order, so that the lower powers were always subjected to the higher, so long as man remained subject to God, as Augustine says (De Civ. Dei xiv, 13). Hence there can be no inordinateness in man, unless first of all the highest part of man were not subject to God, which constitutes a mortal sin. From this it is evident that, in the state of innocence, man could not commit a venial sin, before committing a mortal sin.

[I-II.q.89.a.3.ad.1] In the passage quoted, venial is not taken in the same sense as we take it now; but by venial sin we mean that which is easily forgiven.

[I-II.q.89.a.3.ad.2] This vainglory which preceded man's downfall, was his first mortal sin, for it is stated to have preceded his downfall into the outward act of sin. This vainglory was followed, in the man, by the desire to make and experiment, and in the woman, by doubt, for she gave way to vainglory, merely through hearing the serpent mention the precept, as though she refused to be held in check by the precept.

[I-II.q.89.a.3.ad.3] Mortal sin is opposed to the integrity of the original state in the fact of its destroying that state: this a venial sin cannot do. And because the integrity of the primitive state is incompatible with any inordinateness whatever, the result is that the first man could not sin venially, before committing a mortal sin.

[I-II.q.89.a.4.arg.1] It seems that a good or wicked angel can sin venially. Because man agrees with the angels in the higher part of his soul which is called the mind, according to Gregory, who says (Hom. xxix in Evang.) that "man understands in common with the angels." But man can commit a venial sin in the higher part of his soul. Therefore an angel can commit a venial sin also.

[I-II.q.89.a.4.arg.2] Further, He that can do more can do less. But an angel could love a created good more than God, and he did, by sinning mortally. Therefore he could also love a creature less than God inordinately, by sinning venially.

[I-II.q.89.a.4.arg.3] Further, wicked angels seem to do things which are venial sins generically, by provoking men to laughter, and other like frivolities. Now the circumstance of the person does not make a mortal sin to be venial as stated above (Article 3), unless there is a special prohibition, which is not the case in point. Therefore an angel can sin venially.

[I-II.q.89.a.4.sc] The perfection of an angel is greater than that of man in the primitive state. But man could not sin venially in the primitive state, and much less, therefore, can an angel.

[I-II.q.89.a.4.co] An angel's intellect, as stated above in the I, 58, 3; I, 79, 8, is not discursive, i.e. it does not proceed from principles to conclusions, so as to understand both separately, as we do. Consequently, whenever the angelic intellect considers a conclusion, it must, of necessity, consider it in its principles. Now in matters of appetite, as we have often stated (8, 2; 10, 1; 72, 5), ends are like principles, while the means are like conclusions. Wherefore, an angel's mind is not directed to the means, except as they stand under the order to the end. Consequently, from their very nature, they can have no inordinateness in respect of the means, unless at the same time they have an inordinateness in respect of the end, and this is a mortal sin. Now good angels are not moved to the means, except in subordination to the due end which is God: wherefore all their acts are acts of charity, so that no venial sin can be in them. On the other hand, wicked angels are moved to nothing except in subordination to the end which is their sin of pride. Therefore they sin mortally in everything that they do of their own will. This does not apply to the appetite for the natural good, which appetite we have stated to be in them (I, 63, 4; 64, 2, ad 5).

[I-II.q.89.a.4.ad.1] Man does indeed agree with the angels in the mind or intellect, but he differs in his mode of understanding, as stated above.

[I-II.q.89.a.4.ad.2] An angel could not love a creature less than God, without, at the same time, either referring it to God, as the last end, or to some inordinate end, for the reason given above.

[I-II.q.89.a.4.ad.3] The demons incite man to all such things which seem venial, that he may become used to them, so as to lead him on to mortal sin. Consequently in all such things they sin mortally, on account of the end they have in view.

[I-II.q.89.a.6.arg.1] It would seem that venial sin can be in a man with original sin alone. For disposition precedes habit. Now venial sin is a disposition to mortal sin, as stated above (Question 88, Article 3). Therefore in an unbeliever, in whom original sin is not remitted, venial sin exists before mortal sin: and so sometimes unbelievers have venial together with original sin, and without mortal sins.

[I-II.q.89.a.6.arg.2] Further, venial sin has less in common, and less connection with mortal sin, than one mortal sin has with another. But an unbeliever in the state of original sin, can commit one mortal sin without committing another. Therefore he can also commit a venial sin without committing a mortal sin.

[I-II.q.89.a.6.arg.3] Further, it is possible to fix the time at which a child is first able to commit an actual sin: and when the child comes to that time, it can stay a short time at least, without committing a mortal sin, because this happens in the worst criminals. Now it is possible for the child to sin venially during that space of time, however short it may be. Therefore venial sin can be in anyone with original sin alone and without mortal sin.

[I-II.q.89.a.6.sc] Man is punished for original sin in the children's limbo, where there is no pain of sense as we shall state further on (II-II, 69, 6): whereas men are punished in hell for no other than mortal sin. Therefore there will be no place where a man can be punished for venial sin with no other than original sin.

[I-II.q.89.a.6.co] It is impossible for venial sin to be in anyone with original sin alone, and without mortal sin. The reason for this is because before a man comes to the age of discretion, the lack of years hinders the use of reason and excuses him from mortal sin, wherefore, much more does it excuse him from venial sin, if he does anything which is such generically. But when he begins to have the use of reason, he is not entirely excused from the guilt of venial or mortal sin. Now the first thing that occurs to a man to think about then, is to deliberate about himself. And if he then direct himself to the due end, he will, by means of grace, receive the remission of original sin: whereas if he does not then direct himself to the due end, and as far as he is capable of discretion at that particular age, he will sin mortally, for through not doing that which is in his power to do. Accordingly thenceforward there cannot be venial sin in him without mortal, until afterwards all sin shall have been remitted to him through grace.

[I-II.q.89.a.6.ad.1] Venial sin always precedes mortal sin not as a necessary, but as a contingent disposition, just as work sometimes disposes to fever, but not as heat disposes to the form of fire.

[I-II.q.89.a.6.ad.2] Venial sin is prevented from being with original sin alone, not on account of its want of connection or likeness, but on account of the lack of use of reason, as stated above.

[I-II.q.89.a.6.ad.3] The child that is beginning to have the use of reason can refrain from other mortal sins for a time, but it is not free from the aforesaid sin of omission, unless it turns to God as soon as possible. For the first thing that occurs to a man who has discretion, is to think of himself, and to direct other things to himself as to their end, since the end is the first thing in the intention. Therefore this is the time when man is bound by God's affirmative precept, which the Lord expressed by saying (Zechariah 1:3): "Turn ye to Me . . . and I will turn to you."
