utterly unknowable

"I have lived long enough to appreciate that Christianity is lived more in the valley than on the mountaintop, that faith is never doubt-free, and that although God has revealed Himself in creation and in history, the surest way to know God is, in the words of Thomas Aquinas, as tamquam ignotum, as utterly unknowable. No thought can contain Him, no word can express Him. He is beyond anything we can intellectualize or imagine." -Brennan Manning, Abba's Child
