That the contrary propensities in good and bad angels have arisen, not from a difference in their nature and origin, since God, the good Author and Creator of all essences, created them both, but from a difference in their wills and desires, it is impossible to doubt. While some stedfastly continued in that which was the common good of all, namely, in God Himself, and in His eternity, truth, and love; others, being enamoured rather of their own power, as if they could be their own good, lapsed to this private good of their own, from that higher and beatific good which was common to all, and, bartering the lofty dignity of eternity for the inflation of pride, the most assured verity for the slyness of vanity, uniting love for factious partisanship, they became proud, deceived, envious. The cause, therefore, of the blessedness of the good is adherence to God. And so the cause of the others' misery will be found in the contrary, that is, in their not adhering to God. Wherefore, if when the question is asked, why are the former blessed, it is rightly answered, because they adhere to God; and when it is asked, why are the latter miserable, it is rightly answered, because they do not adhere to God,—then there is no other good for the rational or intellectual creature save God only. Thus, though it is not every creature that can be blessed (for beasts, trees, stones, and things of that kind have not this capacity), yet that creature which has the capacity cannot be blessed of itself, since it is created out of nothing, but only by Him by whom it has been created. For it is blessed by the possession of that whose loss makes it miserable. He, then, who is blessed not in another, but in himself, cannot be miserable, because he cannot lose himself.
