And one should note that earthly affections imitate remotely in some way spiritual affections by which the mind is joined to God, but they can in no way arrive at a similarity with them. For earthly love, and consequently every affection, falls short of the love of God, for love is the source of any affection.
[Thomas Aquinas, The Literal Exposition on Job, Damico, tr. Scholars Press (Atlanta, GA: 1989) p. 80.]
