15.
To sum up generally and briefly the view which, so far as relates to holy living, I entertain concerning virtue,--virtue is the love with which that which ought to be loved is loved. This is in some greater, in others less, and there are men in whom it does not exist at all; but in the absolute fulness which admits of no increase, it exists in no man while living on this earth; so long, however, as it admits of being increased there can be no doubt that, in so far as it is less than it ought to be, the shortcoming proceeds from vice. Because of this vice there is "not a just man upon earth that doeth good and sinneth not;" 1 because of this vice, "in God's sight shall no man living be justified." 2 On account of this vice, "if we say that we have no sin, we deceive ourselves, and the truth is not in us." 3 On account of this also, whatever progress we may have made, we must say, "Forgive us our debts," 4 although all debts in word, deed, and thought were washed away in baptism. He, then, who sees aright, sees whence, and when, and where he must hope for that perfection to which nothing can be added. Moreover, if there had been no commandments, there would have been no means whereby a man might certainly examine himself and see from what things he ought to turn aside, whither he should aspire, and in what things he should find occasion for thanksgiving or for prayer. Great, therefore, is the benefit of commandments, if to free will so much liberty be granted that the grace of God may be more abundantly honoured.
