[Footnote 90: That is, after we have demonstrated that which is involved in the idea of being.]
This is the doctrine of St. Paul, the great father of Christian theology.
"Quis enim hominum, scit quae sunt hominis, nisi spiritus hominis qui in ipso est? Ita, et quae Dei sunt, nemo cognovit, nisi Spiritus Dei."
"For what man knoweth the things of a man, but the spirit of man which is in him? So the things also that are of God, no one knoweth but the Spirit of God."
We understand this to mean, that God alone has naturally the immediate intuition of his own essence and of the interior life and activity of his own being within himself.
"Quod notum est Dei manifestum est in illis, Deus enim illis manifestavit. Invisibilia enim ipsius, a creatura mundi, per ea quae facta sunt intellecta, conspiciuntar; sempiterna quoqne ejus virtus et divinitas." "That which is known of God is manifest in them. For God hath manifested it to them. For the invisible things of him, from the creation of the world, are clearly seen, being understood by the things that are made; his eternal power also and divinity."
That is, God affirms himself distinctly to the reason by the creative act, and simultaneously with the showing which he makes of his works.
"Videmus nunc per speculum in enigmate."
"We see now through a glass in an obscure manner, or more literally, in a riddle, parable, or allegory." [Footnote 91]
