It is curious that there is such an insistence that the doctrine divine simplicity be understood in a univocal or concrete way when its inventors were clear that the language is allegorical. So misunderstood, "God is love" is heard as "God has love," like Santa has love for children. So misunderstood, "God is rational" is heard as "God has an intelligence that can be discerned in the way intelligence is discerned in creatures. So misunderstood, "God is all-powerful" is heard as "God has power" and can therefore be held responsible for human suffering. So misunderstood, the term "God" is understood as something that designates something apart from one's subjective life-experience.
The author of The Cloud of Unknowing, written anonymously in the latter half of the 14th century wrote, "By love he may be gotten and holden; by thought, never." This means that the reality of what human beings call "God" is beyond all debate
