Chapter 14.—The Father and the Son the Only Beginning (Principium) of the Holy Spirit.

15. But in their mutual relation to one another in the Trinity itself, if the begetter is a beginning in relation to that which he begets, the Father is a beginning in relation to the Son, because He begets Him; but whether the Father is also a beginning in relation to the Holy Spirit, since it is said, “He proceeds from the Father,” is no small question. Because, if it is so, He will not only be a beginning to that thing which He begets or makes, but also to that which He gives. And here, too, that question comes to light, as it can, which is wont to trouble many, Why the Holy Spirit is not also a son, since He, too, comes forth from the Father, as it is read in the Gospel.585    John xv. 26 For the Spirit came forth, not as born, but as given; and so He is not called a son, because He was neither born, as the Only-begotten, nor made, so that by the grace of God He might be born into adoption, as we are. For that which is born of the Father, is referred to the Father only when called Son, and so the Son is the Son of the Father, and not also our Son; but that which is given is referred both to Him who gave, and to those to whom He gave; and so the Holy Spirit is not only the Spirit of the Father and of the Son who gave Him, but He is also called ours, who have received Him: as “The salvation of the Lord,”586    Ps. iii. 8 who gives salvation, is said also to be our salvation, who have received it. Therefore, the Spirit is both the Spirit of God who gave Him, and ours who have received Him. Not, indeed, that spirit of ours by which we are, because that is the spirit of a man which is in him; but this Spirit is ours in another mode, viz. that in which we also say, “Give us this day our bread.”587    Matt. vi. 11 Although certainly we have received that spirit also, which is called the spirit of a man. “For what hast thou,” he says, “which thou didst not receive?”588    1 Cor. iv. 7 But that is one thing, which we have received that we might be; another, that which we have received that we might be holy. Whence it is also written of John, that he “came in the spirit and power of Elias;”589    Luke i. 17 and by the spirit of Elias is meant the Holy Spirit, whom Elias received. And the same thing is to be understood of Moses, when the Lord says to him, “And I will take of thy spirit, and will put it upon them;”590    Num. xi. 17 that is, I will give to them of the Holy Spirit, which I have already given to thee. If, therefore, that also which is given has him for a beginning by whom it is given, since it has received from no other source that which proceeds from him; it must be admitted that the Father and the Son are a Beginning of the Holy Spirit, not two Beginnings; but as the Father and Son are one God, and one Creator, and one Lord relatively to the creature, so are they one Beginning relatively to the Holy Spirit. But the Father, the Son, and the Holy Spirit is one Beginning in respect to the creature, as also one Creator and one God.591    [The term “beginning” (principium), when referring to the relation of the Trinity, or of any person of the Trinity, to the creature, denotes creative energy, whereby a new substance is originated from nothing. This is the reference in chapter 13. But when the term refers to the relations of the persons of the Trinity to each other, it denotes only a modifying energy, whereby an existing uncreated substance is communicated by generation and spiration. This is the reference in chapter 14.   When it is said that the Father is the “beginning” of the Son, and the Father and Son are the “beginning” of the Spirit, it is not meant that the substance of the Son is created ex nihilo by the Father, and the substance of the Spirit is created by the Father and Son, but only that the Son by eternal generation receives from the Father the one uncreated and undivided substance of the Godhead, and the Spirit by eternal spiration receives the same numerical substance from the Father and Son. The term “beginning” relates not to the essence, but to the personal peculiarity. Sonship originates in fatherhood; but deity is unoriginated. The Son as the second person “begins” from the Father, because the Father communicates the essence to him. His sonship, not his deity or godhood, “begins” from the Father. And the same holds true of the term “beginning” as applied to the Holy Spirit. The “procession” of the Holy Spirit “begins” by spiration from the Father and Son, but not his deity or godhood.—W.G.T.S.]

CAPUT XIV.

15. Pater et Filius unicum principium Spiritus sancti. Ad se autem invicem in Trinitate, si gignens ad id quod gignit principium est, Pater ad Filium principium est, quia gignit eum . Utrum autem et ad Spiritum sanctum principium sit Pater, quoniam dictum est, De Patre procedit, non parva quaestio est. Quia si ita est, non jam principium ei tantum rei erit quam gignit aut facit, sed etiam ei quam dat. Ubi et illud elucescit, ut potest , quod solet multos movere, cur non Filius sit etiam Spiritus sanctus, cum et ipse a Patre exeat, sicut in Evangelio 0921 legitur (Joan. XV, 26). Exiit enim, non quomodo natus, sed quomodo datus; et ideo non dicitur filius, quia neque natus est sicut Unigenitus, neque factus ut per Dei gratiam in adoptionem nasceretur, sicuti nos. Quod enim de Patre natum est, ad Patrem solum refertur cum dicitur Filius, et ideo Filius Patris, non et noster : quod autem datum est, et ad eum qui dedit refertur, et ad eos quibus dedit; itaque Spiritus sanctus, non tantum Patris et Filii qui dederunt, sed etiam noster dicitur qui accepimus: sicut dicitur, Domini salus qui dat salutem (Psal. III, 9), eadem etiam nostra salus est qui accepimus. Spiritus ergo et Dei est qui dedit, et noster qui accepimus. Non ille spiritus noster quo sumus, quia ipse spiritus est hominis qui in ipso est: sed alio modo iste noster est, quo dicimus et, Panem nostrum da nobis (Matth. VI, 11). Quanquam et illum spiritum qui hominis dicitur, utique accepimus. Quid enim habes, inquit , quod non accepisti (I Cor. IV, 7)? Sed aliud est quod accepimus ut essemus, aliud quod accepimus ut sancti essemus. Unde scriptum est et de Joanne, quod in spiritu et virtute Eliae veniret (Luc. I, 17): dictus est Eliae spiritus, scilicet Spiritus sanctus quem accepit Elias. Hoc et de Moyse intelligendum est, cum ait ei Dominus, Tollam de spiritu tuo, et dabo eis (Num. XI, 17): hoc est, dabo illis de Spiritu sancto, quem jam tibi dedi. Si ergo et quod datur, principium habet eum a quo datur, quia non aliunde accepit illud quod ab ipso procedit; fatendum est Patrem et Filium principium esse Spiritus sancti, non duo principia: sed sicut Pater et Filius unus Deus, et ad creaturam relative unus creator et unus Dominus, sic relative ad Spiritum sanctum unum principium; ad creaturam vero Pater et Filius et Spiritus sanctus unum principium, sicut unus creator et unus Dominus.
