11. And yet They are not Three Eternals, but one Eternal.
Some Account ought to be given of this manner of speaking, because it often occurs in the Creed, and may be thought most apt to offend the malicious, or to mislead the unwary. The way of speaking came in a little after the middle of the fourth Century, and then only into the Latin Church; for the Greeks never used it, but taught the same Things under a different Form of Expression. What Greeks and Latins Both intended was, that as the Three Persons are one Substance and one God, so every divine Perfection, and every substantial Attribute, belonging to any one Person, is common to all; and there is nothing peculiar to any one but the divine Relations: To the Father, Paternity and whatever it implies or carries with it; to the Son, Filiation; to the Holy-Ghost, Procession. In This Account, Eternity, Immensity, Omnipotence, and the like, being substantial Attributes, are common to all the Three Persons; who have therefore one Eternity, one Immensity, one Omnipotence, and so on, as one Substance and one Godhead: Thus far Greeks and Latins agreed both in Doctrine, and Expression. But the Latins, building hereupon, thought it very allowable to go a little farther, (which the Greeks did not) and to express the same Thing by saying, of the Three Persons, that They are one Eternal, one Immense, one Omnipotent, one Holy, one Uncreated, &c. And This was the current Language at the making, and before the making of this Creed. The Arians were the sole Occasion of introducing Both Kinds of Expression, which must therefore be interpreted accordingly. Two Things were design’d by them: One, to obviate the Arian Tenet, that the Three Persons were differing in kind, and in degree, as being of unequal Perfections; the other to obviate the Arian Charge, or Calumny, upon the Church as making Three Gods. In regard to the former, when the Catholicks speak of one Divinity, they intend equal Divinity, not Divinities differing in kind, or degree: And in regard to the latter, They further mean undivided and inseparable Divinity, not Many Divinities. The true meaning then, and the full meaning of the Expressions of the Creed will be very clear and obvious. The Three Persons are equal in Duration, and undivided too; one Eternity, (one, because undivided, and inseparable) is common to all, and therefore They are not Three Eternals, but one Eternal.
The oldest Writers who have used this way of Expression, are, so far as I have observed, Ambrose, Faustinus, and Austin: And their meaning in it is very plain and certain from the Places themselves where They make use of it. Fulgentius, who came not long after them, sometimes falls into the same manner of Expression; but sparingly, as if He either did not fully attend to it, or had some scruple about it: For his general way is to say, not three eternal Gods, but one eternal God, instead of the other in the Creed; and so in the like Cases. Which indeed is a very insipid and dull way of Expressing it, and if applied to every Article in the Athanasian Creed, would make it a very flat composition in comparison to what it is. It is true, that all at length resolves into This, that the Three Persons are not Three Gods, but one God: This is the Ground and Foundation, and the other is the Superstructure. But then it is a fine and elegant, as well as a solid Superstructure; improving the Thought, and carrying on a Train of new and distinct Propositions, and not meerly a jejune and sapless Repetition of the same Thing.
Immensus est Pater, sed immensus est Filius, & immensus est & Spiritus sanctus: Nec tamen tres *Dii* immensi, sed unus *Deus* immensus. *Fulgent.* ibid. p. 232.
Omnipotens est Pater; sed omnipotens est Filius, omnipotens est Spiritus sanctus; Nec tamen tres *Dii* omnipotentes, sed unus *Deus* omnipotens est Pater, & Filius, & Spiritus sanctus. *Fulgent.* ibid.
