Here is a quote from a Patristic theologian (so a theologian from the early church), his name is Epiphanius, and he communicates something about who the Christian God is that will be fundamental for us moving forward in regards to understanding who the Christian God is, and thus is not. I will have to come back an unpack what Epiphanius is articulating later, since the implications of what he is getting at are deep and wide. Here is Epiphanius:

God is one, the Father in the Son, the Son in the Father with the Holy Spirit . . . true enhypostatic Father, and true enhypostatic Son, and true enhypostatic Holy Spirit, three Persons, one Godhead, one being, one glory, one God. In thinking of God you conceive of the Trinity, but without confusing in your mind the Father, the Son and the Holy Spirit. The Father is the Father, the Son is the Son, the Holy Spirit is the Holy Spirit, but there is no deviation in the Trinity from oneness and identity. (Epiphanius, “Anc., 10,” cited by T. F. Torrance, “The Trinitarian Faith,” 234-35)

As you see in the biblio information, Thomas Torrance is the one constructively appropriating Epiphanius for his own unique way of articulating his Doctrine of God as Triune. We will get into this later, and in fact this quote actually is jumping the gun a bit, as far as how I want to go about this series—meaning that I want to move a bit slower than this, by way of introducing key terms, and providing a grammar through which we as Christians can better grasp and understand who are God actually is. This quote presupposes quite a bit, as far as the definitions and grammar that stands behind it; and it is fleshing out this grammar that we will be engaging in the days to come.

Happy Lord’s Day.
