Understanding Divine Simplicity
- Divine simplicity means God is not complex in any respect, lacking parts or components unlike creatures.
- This simplicity coexists with God being tri-personal and the incarnation being composite, showing theological nuance.
Essence as a Metaphysical Component
- Essence is not a separate thing but the defining traits making a being what it is.
- A being's essence can be seen as a component only in a broader metaphysical sense, not a tangible part.
Existence Actualizes Essence
- Existence actualizes essence; essence is potential, existence is actuality.
- Every substance has essence and existence as distinct internal metaphysical principles or components, producing that being's reality.
