Chapter 2. The Catholic Doctrine of the Trinity and Unity, Sometimes Called the Divine Economy, or Dispensation of the Personal Relations of the Godhead
In the course of time, then, the Father forsooth was born, and the Father suffered, God Himself, the Lord Almighty, whom in their preaching they declare to be Jesus Christ. We, however, as we indeed always have done (and more especially since we have been better instructed by the Paraclete, who leads men indeed into all truth), believe that there is one only God, but under the following dispensation, or οἰκονομία, as it is called, that this one only God has also a Son, His Word, who proceeded from Himself, by whom all things were made, and without whom nothing was made. Him we believe to have been sent by the Father into the Virgin, and to have been born of her— being both Man and God, the Son of Man and the Son of God, and to have been called by the name of Jesus Christ; we believe Him to have suffered, died, and been buried, according to the Scriptures, and, after He had been raised again by the Father and taken back to heaven, to be sitting at the right hand of the Father, and that He will come to judge the quick and the dead; who sent also from heaven from the Father, according to His own promise, the Holy Ghost, the Paraclete, the sanctifier of the faith of those who believe in the Father, and in the Son, and in the Holy Ghost. That this rule of faith has come down to us from the beginning of the gospel, even before any of the older heretics, much more before Praxeas, a pretender of yesterday, will be apparent both from the lateness of date which marks all heresies, and also from the absolutely novel character of our new-fangled Praxeas. In this principle also we must henceforth find a presumption of equal force against all heresies whatsoever— that whatever is first is true, whereas that is spurious which is later in date. But keeping this prescriptive rule inviolate, still some opportunity must be given for reviewing (the statements of heretics), with a view to the instruction and protection of various persons; were it only that it may not seem that each perversion of the truth is condemned without examination, and simply prejudged; especially in the case of this heresy, which supposes itself to possess the pure truth, in thinking that one cannot believe in One Only God in any other way than by saying that the Father, the Son, and the Holy Ghost are the very selfsame Person. As if in this way also one were not All, in that All are of One, by unity (that is) of substance; while the mystery of the dispensation is still guarded, which distributes the Unity into a Trinity, placing in their order the three Persons— the Father, the Son, and the Holy Ghost: three, however, not in condition, but in degree; not in substance, but in form; not in power, but in aspect; yet of one substance, and of one condition, and of one power, inasmuch as He is one God, from whom these degrees and forms and aspects are reckoned, under the name of the Father, and of the Son, and of the Holy Ghost. How they are susceptible of number without division, will be shown as our treatise proceeds.
Chapter 3. Sundry Popular Fears and Prejudices. The Doctrine of the Trinity in Unity Rescued from These Misapprehensions
The simple, indeed, (I will not call them unwise and unlearned,) who always constitute the majority of believers, are startled at the dispensation (of the Three in One), on the ground that their very rule of faith withdraws them from the world’s plurality of gods to the one only true God; not understanding that, although He is the one only God, He must yet be believed in with His own οἰκονομία . The numerical order and distribution of the Trinity they assume to be a division of the Unity; whereas the Unity which derives the Trinity out of its own self is so far from being destroyed, that it is actually supported by it. They are constantly throwing out against us that we are preachers of two gods and three gods, while they take to themselves pre-eminently the credit of being worshippers of the One God; just as if the Unity itself with irrational deductions did not produce heresy, and the Trinity rationally considered constitute the truth. We, say they, maintain the Monarchy (or, sole government of God). And so, as far as the sound goes, do even Latins (and ignorant ones too) pronounce the word in such a way that you would suppose their understanding of the μοναρχία ( or Monarchy) was as complete as their pronunciation of the term. Well, then Latins take pains to pronounce the μοναρχία (or Monarchy), while Greeks actually refuse to understand the οἰκονομία, or Dispensation (of the Three in One). As for myself, however, if I have gleaned any knowledge of either language, I am sure that μοναρχία (or Monarchy) has no other meaning than single and individual rule; but for all that, this monarchy does not, because it is the government of one, preclude him whose government it is, either from having a son, or from having made himself actually a son to himself, or from ministering his own monarchy by whatever agents he will. Nay more, I contend that no dominion so belongs to one only, as his own, or is in such a sense singular, or is in such a sense a monarchy, as not also to be administered through other persons most closely connected with it, and whom it has itself provided as officials to itself. If, moreover, there be a son belonging to him whose monarchy it is, it does not immediately become divided and cease to be a monarchy, if the son also be taken as a sharer in it; but it is as to its origin equally his, by whom it is communicated to the son; and being his, it is quite as much a monarchy (or sole empire), since it is held together by two who are so inseparable. Therefore, inasmuch as the Divine Monarchy also is administered by so many legions and hosts of angels, according as it is written, “Thousand thousands ministered unto Him, and ten thousand times ten thousand stood before Him;” Daniel 7:10 and since it has not from this circumstance ceased to be the rule of one (so as no longer to be a monarchy), because it is administered by so many thousands of powers; how comes it to pass that God should be thought to suffer division and severance in the Son and in the Holy Ghost, who have the second and the third places assigned to them, and who are so closely joined with the Father in His substance, when He suffers no such (division and severance) in the multitude of so many angels? Do you really suppose that Those, who are naturally members of the Father’s own substance, pledges of His love, instruments of His might, nay, His power itself and the entire system of His monarchy, are the overthrow and destruction thereof? You are not right in so thinking. I prefer your exercising yourself on the meaning of the thing rather than on the sound of the word. Now you must understand the overthrow of a monarchy to be this, when another dominion, which has a framework and a state peculiar to itself (and is therefore a rival), is brought in over and above it: when, e.g., some other god is introduced in opposition to the Creator, as in the opinions of Marcion; or when many gods are introduced, according to your Valentinuses and your Prodicuses. Then it amounts to an overthrow of the Monarchy, since it involves the destruction of the Creator.
Chapter 4. The Unity of the Godhead and the Supremacy and Sole Government of the Divine Being. The Monarchy Not at All Impaired by the Catholic Doctrine
But as for me, who derive the Son from no other source but from the substance of the Father, and (represent Him) as doing nothing without the Father’s will, and as having received all power from the Father, how can I be possibly destroying the Monarchy from the faith, when I preserve it in the Son just as it was committed to Him by the Father? The same remark (I wish also to be formally) made by me with respect to the third degree in the Godhead, because I believe the Spirit to proceed from no other source than from the Father through the Son. Look to it then, that it be not you rather who are destroying the Monarchy, when you overthrow the arrangement and dispensation of it, which has been constituted in just as many names as it has pleased God to employ. But it remains so firm and stable in its own state, notwithstanding the introduction into it of the Trinity, that the Son actually has to restore it entire to the Father; even as the apostle says in his epistle, concerning the very end of all: “When He shall have delivered up the kingdom to God, even the Father; for He must reign till He has put all enemies under His feet;” 1 Corinthians 15:24-25 following of course the words of the Psalm: “Sit on my right hand, until I make Your enemies Your footstool.” “When, however, all things shall be subdued to Him, (with the exception of Him who did put all things under Him,) then shall the Son also Himself be subject unto Him who put all things under Him, that God may be all in all.” 1 Corinthians 15:27-28 We thus see that the Son is no obstacle to the Monarchy, although it is now administered by the Son; because with the Son it is still in its own state, and with its own state will be restored to the Father by the Son. No one, therefore, will impair it, on account of admitting the Son (to it), since it is certain that it has been committed to Him by the Father, and by and by has to be again delivered up by Him to the Father. Now, from this one passage of the epistle of the inspired apostle, we have been already able to show that the Father and the Son are two separate Persons, not only by the mention of their separate names as Father and the Son, but also by the fact that He who delivered up the kingdom, and He to whom it is delivered up— and in like manner, He who subjected (all things), and He to whom they were subjected— must necessarily be two different Beings.
