On the contrary, In Scripture, charity is compared to fire, according to Cant 8:6: "The lamps thereof," i.e. of charity, "are fire and flames." Now fire ever mounts upward so long as it lasts. Therefore as long as charity endures, it can ascend, but cannot descend, i.e. decrease.

I answer that, The quantity which charity has in comparison with its proper object, cannot decrease, even as neither can it increase, as stated above (A. 4, ad 2).

Since, however, it increases in that quantity which it has in comparison with its subject, here is the place to consider whether it can decrease in this way. Now, if it decrease, this must needs be either through an act, or by the mere cessation from act. It is true that virtues acquired through acts decrease and sometimes cease altogether through cessation from act, as stated above (I-II, Q. 53, A. 3). Wherefore the Philosopher says, in reference to friendship (Ethic. viii, 5) "that want of intercourse," i.e. the neglect to call upon or speak with one's friends, "has destroyed many a friendship." Now this is because the safe-keeping of a thing depends on its cause, and the cause of human virtue is a human act, so that when human acts cease, the virtue acquired thereby decreases and at last ceases altogether. Yet this does not occur to charity, because it is not the result of human acts, but is caused by God alone, as stated above (A. 2). Hence it follows that even when its act ceases, it does not for this reason decrease, or cease altogether, unless the cessation involves a sin.
