A worked analysis beyond the introductory statement
The divine attributes are not independent pieces assembled into a supreme object. They are distinct concepts by which the finite intellect knows one simple actuality. God's being, goodness, knowledge and power are identical in reality, though each term removes a different creaturely limitation and expresses a different relation to effects.
Pure act excludes passive potency. What can acquire or lose a perfection is not the first source of actuality. This yields immutability, not inertness: God possesses the fullness of actuality in one eternal act and causes temporal change without passing from potency to act.
Simplicity excludes composition of matter and form, essence and existence, substance and accidents, or metaphysical parts. Every composition depends upon principles and a unifier. The first cause cannot receive unity from components. Divine simplicity therefore follows from causal primacy rather than from an arbitrary preference for minimality.
Immateriality follows because matter is potency to form and quantity. Eternity follows because time measures change; the immutable source does not pass through successive states. Infinity follows not as endless quantity but as absence of a limiting receptive principle in subsistent being.
Intellect is attributed because the first cause contains eminently the intelligibility found in effects and because ordered finality presupposes knowledge. Will follows intellect's apprehension of good. Divine freedom means the created order is not a necessary emanation; God wills His own goodness necessarily and creatures freely as finite participations.
Omnipotence extends to every real possibility, not contradictions, which describe no possible being. Goodness is not external conformity to a law above God; the divine essence is subsistent good and the source of the order by which creaturely acts are measured.
