Whether charity increases by addition?

❌ Objection 1 : It would seem that charity increases by addition. For just as increase may be in respect of bodily quantity, so may it be according to virtual quantity. Now increase in bodily quantity results from addition; for the Philosopher says (De Gener. i, 5) that "increase is addition to pre-existing magnitude." Therefore the increase of charity which is according to virtual quantity is by addition.

❌ Objection 2 : Further, charity is a kind of spiritual light in the soul, according to 1 Jn. 2:10: "He that loveth his brother abideth in the light." Now light increases in the air by addition; thus the light in a house increases when another candle is lit. Therefore charity also increases in the soul by addition.

❌ Objection 3 : Further, the increase of charity is God's work, even as the causing of it, according to 2 Cor. 9:10: "He will increase the growth of the fruits of your justice." Now when God first infuses charity, He puts something in the soul that was not there before. Therefore also, when He increases charity, He puts something there which was not there before. Therefore charity increases by addition.
