XI. Now 'tis plainly impossible that any things should have place in the Essence of God, of such a Nature as Species, or Magnitude, or Quantity; because on all accounts God, must be free from all Composition. But now, if it can never be agreeable to Piety, to suppose these or any the like Circumstances connected with the Substance of God, how can Reason admit us to equal a Begotten Substance to that which is Unbegotten? seeing that all Likeness, or Comparifon, or Communication of Substance leaves no Supereminence, or Difference, but implies a plain Equality; and by that Equality declares him that is so intire like the other, to be equally Unbegotten also. But no one is so mad and daring in his Impiety, as to assert that the Son is Equal to the Father, when the Lord himself expressly says, The Father, who sent me, is Greater than I:³ or to apply both of the Names at random, while each claims the Appropriation, nor does admit the Communication thereof to the other. For if either Person be Unbegotten, he is not a Son; and if he be a Son, he is not Unbegotten. But that there is only one God of the Universe Unbegotten, and beyond all comparison, besides the many Arguments omitted here, what we have said already upon that Subject does sufficiently demonstrate.
