"the Divine love produces ecstasy, for it takes the lover away from himself and gives him to the beloved." Therefore devotion is an act of charity rather than of religion.
Obj. 2: Further, charity precedes religion; and devotion seems to precede charity; since, in the Scriptures, charity is represented by fire, while devotion is signified by fatness which is the material of fire [*Cant. 8:6; Ps. 52:6]. Therefore devotion is not an act of religion.
Obj. 3: Further, by religion man is directed to God alone, as stated above (Q. 81, A. 1). But devotion is directed also to men; for we speak of people being devout to certain holy men, and subjects are said to be devoted to their masters; thus Pope Leo says [*Serm. viii, De Pass. Dom.] that the Jews "out of devotion to the Roman laws," said: "We have no king but Caesar." Therefore devotion is not an act of religion.
On the contrary, Devotion is derived from devovere, as stated (A. 1). But a vow is an act of religion. Therefore devotion is also an act of religion.
I answer that, It belongs to the same virtue, to will to do something, and to have the will ready to do it, because both acts have the same object. For this reason the Philosopher says (Ethic. v, 1): "It is justice whereby men both will end do just actions." Now it is evident that to do what pertains to the worship or service of God, belongs properly to religion, as stated above (Q. 81). Wherefore it belongs to that virtue to have the will ready to do such things, and this is to be devout. Hence it is evident that devotion is an act of religion.
Reply Obj. 1: It belongs immediately to charity that man should give himself to God, adhering to Him by a union of the spirit; but it belongs immediately to religion, and, through the medium of religion, to charity which is the principle of religion, that man should give himself to God for certain works of Divine worship.
Reply Obj. 2: Bodily fatness is produced by the natural heat in the process of digestion, and at the same time the natural heat thrives, as it were, on this fatness. In like manner charity both causes devotion (inasmuch as love makes one ready to serve one's friend) and feeds on devotion. Even so all friendship is safeguarded and increased by the practice and consideration of friendly deeds.
Reply Obj. 3: Devotion to God's holy ones, dead or living, does not terminate in them, but passes on to God, in so far as we honor God in His servants. But the devotion of subjects to their temporal masters is of another kind, just as service of a temporal master differs from the service of God.
THIRD ARTICLE [II-II, Q. 82, Art. 3]
Whether Contemplation or Meditation Is the Cause of Devotion?
Objection 1: It would seem that contemplation or meditation is not the cause of devotion. No cause hinders its effect. But subtle considerations about abstract matters are often a hindrance to devotion. Therefore contemplation or meditation is not the cause of devotion.
Obj. 2: Further, if contemplation were the proper and essential cause of devotion, the higher objects of contemplation would arouse greater devotion. But the contrary is the case: since frequently we are urged to greater devotion by considering Christ's Passion and other mysteries of His humanity than by considering the greatness of His Godhead. Therefore contemplation is not the proper cause of devotion.
Obj. 3: Further, if contemplation were the proper cause of devotion, it would follow that those who are most apt for contemplation, are also most apt for devotion. Yet the contrary is to be noticed, for devotion is frequently found in men of simplicity and members of the female sex, who are defective in contemplation. Therefore contemplation is not the proper cause of devotion.
