Philo Judaeus Quod Deterius Potiori Insidiari Soleat 86

Let us then no longer doubt, we who are the disciples of Moses, how man conceived an idea of God who is destitute of all figure, for he was taught the reason of this by the divine oracle, and afterwards he explained it to us. And he spoke as follows:—"He said that the Creator made no soul in any body capable of seeing its Creator by its own intrinsic powers. But having considered that the knowledge of the Creator and the proper understanding of the work of Creation, would be of great advantage to the creature (for such knowledge is the boundary of happiness and blessedness), he breathed into him from above something of his own divine nature. And his divine nature stamped her own impression in an invisible manner on the invisible soul, in order that even the earth might not be destitute of the image of God.
