No one could be more reserved than me before any attempt to employ Being to think theologically about God. There’s nothing to expect from Being here. I believe that Being can never be thought as the ground and essence of God, but that nevertheless the experience of God and of his manifestedness, to the extent that the latter can indeed meet man, flashes in the field of Being, which in no way means that Being can be seen as a possible ground for God.
— Heidegger
