Lactantius

“ For if you will contemplate the world, with all the things which it contains, you will assuredly understand how much the work of God surpasses the works of men. Thus, as great as is the difference between divine and human works, so great must be the distance between the wisdom of God and man. For because God is incorruptible and immortal, and therefore perfect because He is everlasting, His wisdom also is perfect, as He Himself is ”

“ But because man is subject to passion, his wisdom also is subject to error; and as many things hinder the life of man, so that it cannot be perpetual, so also his wisdom must be hindered by many things: so that it is not perfect in entirely perceiving the truth. Therefore there is no human wisdom, if it strives by itself to attain to the conception and knowledge of the truth; inasmuch as the mind of man, being bound up with a frail body, and enclosed in a dark abode, is neither able to wander at large, nor clearly to perceive the truth, the knowledge of which belongs to the divine nature. ”

“ And this knowledge, as I have often said already, cannot exist in a man unless it is derived from the teaching of God. For if a man is able to understand divine things, he will be able also to perform them; for to understand is, as it were, to follow in their track. But he is not able to do the things which God does, because he is clothed with a mortal body; therefore he cannot even understand those things which God does. ”
