“The Father is made of none,” says the Athanasian Creed, “neither created nor begotten. The Son is of the Father alone, not made, nor created, but begotten. The Holy Spirit is of the Father and the Son: not made nor created, nor begotten, but proceeding.” God exists in Himself and of Himself. His being He owes to no one. His substance is indivisible. He has no parts but is single in His unitary being.
