Tertullian

If any material was necessary to God in the creation of the world, as Hermogenes supposed, God had a far nobler and more suitable one in His own wisdom -one which was not to be gauged by the writings of philosophers, but to be learnt from the words of prophets. This alone, indeed, knew the mind of the Lord. For "who knoweth the things of God, and the things in God, but the Spirit, which is in Him? " Now His wisdom is that Spirit. This was His counsellor, the very way of His wisdom and knowledge.
