God is the source of all activity throughout creation. He cannot be seen or described in his own nature and in all his greatness by any of his creatures. Yet he is certainly not unknown. Through his Word the whole creation learns that there is one God the Father, who holds all things together and gives them their being. As it is written in the Gospel, "No man has ever seen God, except the only-begotten Son, who is in the bosom of the Father; he has revealed him."
-- Saint Irenaeus of Lyons
