It does not follow because men are endowed with greater and less degrees of intelligence, that they should therefore change the subject-matter [of the faith] itself, and should conceive of some other God besides Him who is the Framer, Maker, and Preserver of this universe, (as if He were not sufficient for them), or of another Christ, or another Only-begotten. But the fact referred to simply implies this, that one may [more accurately than another] bring out the meaning of those things which have been spoken in parables, and accommodate them to the general scheme of the faith; and explain [with special clearness] the operation and dispensation of God connected with human salvation; and show that God manifested longsuffering in regard to the apostasy of the angels who transgressed, as also with respect to the disobedience of men; and set forth why it is that one and the same God has made some things temporal and some eternal, some heavenly and others earthly; and understand for what reason God, though invisible, manifested Himself to the prophets not under one form, but differently to different individuals; and show why it was that more covenants than one were given to mankind; and teach what was the special character of each of these covenants; and search out for what reason "God hath concluded every man in unbelief, that He may have mercy upon all;" and gratefully describe on what account the Word of God became flesh and suffered; and relate why the advent of the Son of God took place in these last times, that is, in the end, rather than in the beginning [of the world]; and unfold what is contained in the Scriptures concerning the end [itself], and things to come; and not be silent as to how it is that God has made the Gentiles, whose salvation was despaired of, fellow-heirs, and of the same body, and partakers with the saints; and discourse how it is that "this mortal body shall put on immortality, and this corruptible shall put on incorruption;" and proclaim in what sense [God] says, "That is a people who was not a people; and she is beloved who was not beloved;" and in what sense He says that "more are the children of her that was desolate, than of her who possessed a husband." For in reference to these points, and others of a like nature, the apostle exclaims: "Oh! the depth of the riches both of the wisdom and knowledge of God; how unsearchable are His judgments, and His ways past finding out!" But [the superior skill spoken of] is not found in this, that any one should, beyond the Creator and Framer [of the world], conceive of the Enthymesis of an erring Aeon, their mother and his, and should thus proceed to such a pitch of blasphemy; nor does it consist in this, that he should again falsely imagine, as being above this [fancied being], a Pleroma at one time supposed to contain thirty, and at another time an innumerable tribe of Aeons, as these teachers who are destitute of truly divine wisdom maintain; while the Catholic Church possesses one and the same faith throughout the whole world, as we have already said.

They moreover affirm that the Saviour is shown to be derived from all the Aeons, and to be in Himself everything by the following passage: "Every male that openeth the womb." For He, being everything, opened the womb of the enthymesis of the suffering Aeon, when it had been expelled from the Pleroma. This they also style the second Ogdoad, of which we shall speak presently. And they state that it was clearly on this account that Paul said, "And He Himself is all things;" and again, "All things are to Him, and of Him are all things;" and further, "In Him dwelleth all the fulness of the Godhead;" and yet again, "All things are gathered together by God in Christ." Thus do they interpret these and any like passages to be found in Scripture.

(de Trin. ii. 1 &c.) For what part of the salvation of men is there that is not contained in this Sacrament? All things are full and perfect, as proceeding from Him who is full and perfect. The nature of His relation is expressed in the title Father; but He is nothing but Father; for not after the manner of men does He derive from somewhat else that He is Father, being Himself Unbegotten, Eternal, and having the source of His being in Himself, known to none, save the Son. The Son is the Offspring of the Unbegotten, One of the One, True of the True, Living of the Living, Perfect of the Perfect, Strength of Strength, Wisdom of Wisdom, Glory of Glory; the Image of the Unseen God, the Form of the Unbegotten Father. Neither can the Holy Spirit be separated from the confession of the Father and the Son. And this consolation of our longing desires is absent from no place. He is the pledge of our hope in the effects of His gifts, He is the light of our minds, He shines in our souls. These things as the heretics cannot change, they introduce into them their human explanations. As Sabellius who identifies the Father with the Son, thinking the distinction to be made rather in name than in person, and setting forth one and the same Person as both Father and Son. As Ebion, who deriving the beginning of His existence from Mary, makes Him not Man of God, but God of man. As the Arians, who derive the form, the power, and the wisdom of God out of nothing, and in time. What wonder then that men should have diverse opinions about the Holy Spirit, who thus rashly after their own pleasure create and change the Son, by whom that Spirit is bestowed?
