SECOND ARTICLE [I, Q. 111, Art. 3]

Whether the Angels Can Change the Will of Man?

Objection 1: It would seem that the angels can change the will of

man. For, upon the text, "Who maketh His angels spirits and His

ministers a flame of fire" (Heb. 1:7), the gloss notes that "they are

fire, as being spiritually fervent, and as burning away our vices."

This could not be, however, unless they changed the will. Therefore

the angels can change the will.

Obj. 2: Further, Bede says (Super Matth. xv, 11), that, "the devil

does not send wicked thoughts, but kindles them." Damascene, however,

says that he also sends them; for he remarks that "every malicious

act and unclean passion is contrived by the demons and put into men"

(De Fide Orth. ii, 4); in like manner also the good angels introduce

and kindle good thoughts. But this could only be if they changed the

will. Therefore the will is changed by them.

Obj. 3: Further, the angel, as above explained, enlightens the human

intellect by means of the phantasms. But as the imagination which

serves the intellect can be changed by an angel, so can the sensitive

appetite which serves the will, because it also is a faculty using a

corporeal organ. Therefore as the angel enlightens the mind, so can

he change the will.

_On the contrary,_ To change the will belongs to God alone, according

to Prov. 21:1: "The heart of the king is in the hand of the Lord,

whithersoever He will He shall turn it."

_I answer that,_ The will can be changed in two ways. First, from

within; in which way, since the movement of the will is nothing but

the inclination of the will to the thing willed, God alone can thus

change the will, because He gives the power of such an inclination to

the intellectual nature. For as the natural inclination is from God

alone Who gives the nature, so the inclination of the will is from

God alone, Who causes the will.

Secondly, the will is moved from without. As regards an angel, this

can be only in one way--by the good apprehended by the intellect.

Hence in as far as anyone may be the cause why anything be apprehended

as an appetible good, so far does he move the will. In this way also

God alone can move the will efficaciously; but an angel and man move

the will by way of persuasion, as above explained (Q. 106, A. 2).

In addition to this mode the human will can be moved from without in

another way; namely, by the passion residing in the sensitive

appetite: thus by concupiscence or anger the will is inclined to will

something. In this manner the angels, as being able to rouse these

passions, can move the will, not however by necessity, for the will

ever remains free to consent to, or to resist, the passion.

Reply Obj. 1: Those who act as God's ministers, either men or angels,

are said to burn away vices, and to incite to virtue by way of

persuasion.

Reply Obj. 2: The demon cannot put thoughts in our minds by causing

them from within, since the act of the cogitative faculty is subject

to the will; nevertheless the devil is called the kindler of

thoughts, inasmuch as he incites to thought, by the desire of the

things thought of, by way of persuasion, or by rousing the passions.

Damascene calls this kindling "a putting in" because such a work is

accomplished within. But good thoughts are attributed to a higher

principle, namely, God, though they may be procured by the ministry

of the angels.

Reply Obj. 3: The human intellect in its present state can understand

only by turning to the phantasms; but the human will can will

something following the judgment of reason rather than the passion of

the sensitive appetite. Hence the comparison does not hold.
