Aseitous

Now we return to our other analogue in the framework of our analogy between the Absolute and God. The same difference distinguishing the former from any other entity (emergent or part) also holds with regard to differentiating God from any other ‘truth,' thereby establishing His transcendency and uniqueness. The same difference applies to the aseitous Truth-God as contrasted with any other (or all) partial, limited, aspectual, ephemeral, contingent, dependent, derived, empirical or merely rational (a sub-division of Wisdom) truth however comprehensive it be but short of being applicable to and explanatory of the All-under-the-aspect-of-eternity from chaos to cosmos to the Absolute.

My contingence can be presented in two languages: my existence is pure fact, and my existence is not aseitous, even though of myself I necessarily possess sovereign control of choice and of motion.

Revelation is a free act of divine self-disclosure, the act of a personal God who chooses to make himself known, and God remains inapprehensible -- unknowable and inaccessible -- aprt from his revealing himself. Yet we cannot think of this freedom in a nominalistic way. God need not create or engage in any ad extra work, for he is aseitous (self-contained).
