And God saw everything that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.
All Commentaries on Genesis 1:31 Go To Genesis 1
Thomas Aquinas
AD 1274
God saw all the things that He had made, and they were very good: But among them were also the demons. Therefore the demons were at some time good.
Corporeal creatures according to their nature are good, though this good is not universal, but partial and limited, the consequence of which is a certain opposition of contrary qualities, though each quality is good in itself. To those, however, who estimate things, not by the nature thereof, but by the good they themselves can derive therefrom, everything which is harmful to themselves seems simply evil. For they do not reflect that what is in some way injurious to one person, to another is beneficial, and that even to themselves the same thing may be evil in some respects, but good in others. And this could not be, if bodies were essentially evil and harmful.
