Context

“and these sins, indeed, are like obstacles interposed between us and God, according to Isa. 59:2: "Our sins have divided between us and God." Yet the aforesaid aptitude of the soul is not wholly taken away, for it belongs to its very nature. Reply Obj. 1: The good which is opposed to evil is wholly taken away; but other goods are not wholly removed, as said above. Reply Obj. 2: The aforesaid aptitude is a medium between subject and act. Hence, where it touches act, it is diminished by evil; but where it touches the subject, it remains as it was.” source
