He made His world of contradictions, opposites that combine as one.

At their nexus, a world is formed: Neither can exist without the other, all function together as a single whole.

Being and not being,
infinity and finitude,
light and darkness,
form and matter,
quantity and quality,
giving and withholding.
the whole and the fragment
the community and the individual
miracle and nature.

They are mere modalities—He Himself is none of them. He mixes and matches them at whim.

Paradox is our window upon the Unknowable.
