He was not enclosed in the body, nor was he in the body but nowhere else. Nor did he move the latter while the universe was deprived of his action and providence. But was is most wonderful is that, being the Word, he was not contained by anyone, but rather himself contained everything. And as he is in all creation, he is in essence outside the universe but in everything by his power, ordering everything and extending his providence over everything. And giving life to all, separately and together, he contains the universe and is not contained, but in his Father only he is complete in everything. So also being in a human body and giving it life himself, he accordingly gives life to everything, and was both in all and outside all. And although he was known by his body through his works, yet he was not invisible by his action on the universe.
