"The virtue of gratitude is extremely commendable and pleasing in the sight of God, as its opposite is a detestable vice before him. Of which subject, thus speaks St. Bernard: Learn to be thankful for every grace received. Consider diligently the favors heaped upon you, that no gift of God be defrauded of the due return of gratitude and thanksgiving you ought to make, whether the gift be great, middling, or little."
