Nevertheless, we can make a distinction between the three persons of the Trinity, because each member of the Godhead has unique attributes. We say the Father is God, the Son is God, and the Holy Spirit is God, but we don't say that the Father is the Son, the Son is the Holy Spirit, or the Holy Spirit is the Father. There are distinctions between them, but the distinctions are not essential, not of the essence. They are real, but they do not disturb the essence of deity. The distinctions within the Godhead are, if you will, sub-distinctions within the essence of God. He is one essence, three subsistences. That is about as close as we can get to articulating the historic doctrine of the Trinity.
