He who loves God both believes truly and performs the works of faith reverently.
But he who only believes and does not love, lacks even the faith he thinks he has; for he believes merely with a certain superficiality of intellect and is not energized by the full force of love’s glory. The chief part of virtue, then, is faith energized by love.
