Whether by Penance one sin can be pardoned without another?

❌ Objection 1 : It would seem that by Penance one sin can be pardoned without another. For it is written (Amos 4:7): "I caused it to rain upon one city, and caused it not to rain upon another city; one piece was rained upon: and the piece whereupon I rained not, withered." These words are expounded by Gregory, who says (Hom. x super Ezech.): "When a man who hates his neighbor, breaks himself of other vices, rain falls on one part of the city, leaving the other part withered, for there are some men who, when they prune some vices, become much more rooted in others." Therefore one sin can be forgiven by Penance, without another.

❌ Objection 2 : Further, Ambrose in commenting on Ps. 118, "Blessed are the undefiled in the way," after expounding verse 136 ("My eyes have sent forth springs of water"), says that "the first consolation is that God is mindful to have mercy; and the second, that He punishes, for although faith be wanting, punishment makes satisfaction and raises us up." Therefore a man can be raised up from one sin, while the sin of unbelief remains.

❌ Objection 3 : Further, when several things are not necessarily together, one can be removed without the other. Now it was stated in the FS, Question [73], Article [1] that sins are not connected together, so that one sin can be without another. Therefore also one sin can be taken away by Penance without another being taken away.

❌ Objection 4 : Further, sins are the debts, for which we pray for pardon when we say in the Lord's Prayer: "Forgive us our trespasses," etc. Now man sometimes forgives one debt without forgiving another. Therefore God also, by Penance, forgives one sin without another.

❌ Objection 5 : Further, man's sins are forgiven him through the love of God, according to Jer. 31:3: "I have loved thee with an everlasting love, therefore have I drawn thee, taking pity on thee." Now there is nothing to hinder God from loving a man in one respect, while being offended with him in another, even as He loves the sinner as regards his nature, while hating him for his sin. Therefore it seems possible for God, by Penance, to pardon one sin without another.
