Chapter I.—There is but one God: the impossibility of its being otherwise. 1. It is proper, then, that I should begin with the first and most important head, that is, God the Creator, who made the heaven and the earth, and all things that are therein (whom these men blasphemously style the fruit of a defect), and to demonstrate that there is nothing either above Him or after Him; nor that, influenced by any one, but of His own free will, He created all things, since He is the only God, the only Lord, the only Creator, the only Father, alone containing all things, and Himself commanding all things into existence. 2. For how can there be any other Fulness, or Principle, or Power, or God, above Him, since it is matter of necessity that God, the Pleroma (Fulness) of all these, should contain all things in His immensity, and should be contained by no one? But if there is anything beyond Him, He is not then the Pleroma of all, nor does He contain all. For that which they declare to be beyond Him will be wanting to the Pleroma, or, [in other words,] to that God 360 who is above all things. But that which is wanting, and falls in any way short, is not the Pleroma of all things. In such a case, He would have both beginning, middle, and end, with respect to those who are beyond Him. And if He has an end in regard to those things which are below, He has also a beginning with respect to those things which are above. In like manner, there is an absolute necessity that He should experience the very same thing at all other points, and should be held in, bounded, and enclosed by those existences that are outside of Him. For that being who is the end downwards, necessarily circumscribes and surrounds him who finds his end in it. And thus, according to them, the Father of all (that is, He whom they call Proön and Proarche), with their Pleroma, and the good God of Mar- cion, is established and enclosed in some other, and is surrounded from without by another mighty Being, who must of necessity be greater, inasmuch as that which contains is greater than that which is contained. But then that which is greater is also stronger, and in a greater degree Lord; and that which is greater, and stronger, and in a greater degree Lord—must be God. 3. Now, since there exists, according to them, also something else which they declare to be outside of the Pleroma, into which they further hold there descended that higher power who went astray, it is in every way necessary that the Pleroma either contains that which is beyond, yet is contained (for otherwise, it will not be beyond the Pleroma; for if there is anything beyond the Pleroma, there will be a Pleroma within this very Pleroma which they declare to be outside of the Pleroma, and the Pleroma will be contained by that which is beyond: and with the Pleroma is understood also the first God); or, again, they must be an infinite distance separated from each other —the Pleroma [I mean], and that which is beyond it. But if they maintain this, there will then be a third kind of existence, which separates by immensity the Pleroma and that which is beyond it. This third kind of existence will therefore bound and contain both the others, and will be greater both than the Pleroma, and than that which is beyond it, inasmuch as it contains both in its bosom.
