“The same argument applies to the Holy Spirit. The essence of the Holy Spirit is the divine essence. The Holy Spirit has the whole undivided divine essence. He is, therefore, God, in himself.”
― Samuel D. Renihan, Deity and Decree

“Of each person, we can ask, “Does the Father, or the Son, or the Holy Spirit, have the whole divine essence?” We answer, “Yes,” and we say, therefore, that each one, in himself, is God with respect to the divine essence. Then we can ask, of each one, “In what manner does this person have the divine essence?” And we answer that The Father is of none, the Son is begotten eternally of the Father, and the Holy Spirit proceeds eternally from the Father and the Son. The result is that the essence of the Son is the divine essence. The Son has the whole undivided divine essence. He is, therefore, God, in himself. But his subsistence, the way in which he has the whole divine essence, is from the Father. He is God, in himself (essence), but not of himself (subsistence).”
― Samuel D. Renihan, Deity and Decree

“The Father is the principle of origin of the persons of the Holy Trinity: He is not a principle of nature or time. The Father is called principle, but neither the Son nor the Spirit has had a beginning. The Son originates from the Father in respect of the mode of subsistence in the essence, not in respect of the essence itself.”
― Samuel D. Renihan, Deity and Decree

“The decree is the act of God by which he determines, absolutely, the existence and infallible future (or futurition) of all that is outside of himself, to the praise of his own glory, the first cause and Director of all things, the Antecedent and Governor of all events.”
