Truth, goodness, and beauty are so fully transcendental properties of being that they can be grasped only in and through one another. In their communion, they furnish proof of the inexhaustible depth and overflowing richness of being. Finally, they show that in the end everything is comprehensible and unveiled only because it is grounded in an ultimate mystery, whose mysteriousness rests, not upon a lack of clarity, but rather upon a super abundance of light. For what is more incomprehensible than the fact that the core of being consists in love and that its emergence as essence and existence has no ground other than groundless grace?
Hans urs van Balthasar, Truth of the World
