On the part of the person who loves, charity is perfect, when he loves as much as he can. This happens in three ways. First, so that a man's whole heart is always actually borne towards God: this is the perfection of the charity of heaven, and is not possible in this life, wherein, by reason of the weakness of human life, it is impossible to think always actually of God, and to be moved by love towards Him. Secondly, so that man makes an earnest endeavor to give his time to God and Divine things, while scorning other things except in so far as the needs of the present life demand. This is the perfection of charity that is possible to a wayfarer; but is not common to all who have charity. Thirdly, so that a man gives his whole heart to God habitually, viz. by neither thinking nor desiring anything contrary to the love of God; and this perfection is common to all who have charity. Reply Obj. 1: The Apostle denies that he has the perfection of heaven, wherefore a gloss on the same passage says that "he was a perfect wayfarer, but had not yet achieved the perfection to which the way leads." Reply Obj. 2: This is said on account of venial sins, which are contrary, not to the habit, but to the act of charity: hence they are incompatible, not with the perfection of the way, but with that of heaven. Reply Obj. 3: The perfection of the way is not perfection simply, wherefore it can always increase. _______________________ NINTH ARTICLE [II-II, Q. 24, Art. 9] Whether Charity Is Rightly Distinguished into Three Degrees, Beginning, Progress, and Perfection? Objection 1: It would seem unfitting to distinguish three degrees of charity, beginning, progress, and perfection. For there are many degrees between the beginning of charity and its ultimate perfection. Therefore it is not right to put only one. Obj. 2: Further, charity begins to progress as soon as it begins to be. Therefore we ought not to distinguish between charity as progressing and as beginning. Obj. 3: Further, in this world, however perfect a man's charity may be, it can increase, as stated above (A. 7). Now for charity to increase is to progress. Therefore perfect charity ought not to be distinguished from progressing charity: and so the aforesaid degrees are unsuitably assigned to charity. _On the contrary,_ Augustine says (In prim. canon. Joan. Tract. v) "As soon as charity is born it takes food," which refers to beginners, "after taking food, it waxes strong," which refers to those who are progressing, "and when it has become strong it is perfected," which refers to the perfect. Therefore there are three degrees of charity.
