Obj. 2: Further, just as the habits of acquired virtue are engendered by acts, so too an increase of charity is caused by an act of charity. Now each virtuous act conduces to the engendering of virtue. Therefore also each virtuous act of charity conduces to the increase of charity.

Obj. 3: Further, Gregory [*St. Bernard, Serm. ii in Festo Purif.] says that "to stand still in the way to God is to go back." Now no man goes back when he is moved by an act of charity. Therefore whoever is moved by an act of charity goes forward in the way to God. Therefore charity increases through every act of charity.

On the contrary, The effect does not surpass the power of its cause. But an act of charity is sometimes done with tepidity or slackness. Therefore it does not conduce to a more excellent charity, rather does it dispose one to a lower degree.

I answer that, The spiritual increase of charity is somewhat like the increase of a body. Now bodily increase in animals and plants is not a continuous movement, so that, to wit, if a thing increase so much in so much time, it need to increase proportionally in each part of that time, as happens in local movement; but for a certain space of time nature works by disposing for the increase, without causing any actual increase, and afterwards brings into effect that to which it had disposed, by giving the animal or plant an actual increase. In like manner charity does not actually increase through every act of charity, but each act of charity disposes to an increase of charity, in so far as one act of charity makes man more ready to act again according to charity, and this readiness increasing, man breaks out into an act of more fervent love, and strives to advance in charity, and then his charity increases actually.
