|Bernard of Clairvaux (1090-1153)|
To love in this way is to become like God. As a drop of water seems to disappear completely in a quantity of wine, taking the wine's flavor and color; as red-hot iron becomes indistinguishable from the glow of fire and its own original form disappears; as air suffused with the light of the sun seems transformed into the brightness of the light, as if it were itself light rather than merely lit up; so, in those who are holy, it is necessary for human affection to dissolve in some ineffable way, and be poured into the will of God. How will God be all in all (1 Cor 15:26), if anything of man remains in man? The substance remains, but in another form, with another glory, another power."
(Bernard of Clairvaux, "On Loving God")
