"By spiration, the Father and Son make the eternal Essence common to themselves and the Spirit. They are not two Persons that exist prior to the Third, but [They] eternally co-exist with Him. The co-existence, in both generation [of the Son by the Father in the Spirit] and spiration [of the Spirit by the Father and the Son], follows from the fact that it is One and the Same…Essence which is communicated and constitutes the substance of Each Person. And this Essence cannot be any older in One Person than in Another…. The procession of the Spirit is by the mode of the will and affections, and hence the Spirit is called Love."
