I recently read the essay "On "Not Three Gods' - Again: Can a Primary-Secondary substance reading of ousia and hypostasis avoid tritheism?"
Throughout the essay, the author, Nathan Jacobs, defines the Trinity in terms of Aristotelian language (using primary and secondary substances). In this way, he says that the Godhead can be understood as a secondary substance, while the persons in the Trinity as primary substance ("this line of analogy for the Godhead exists throughout the Cappadocian fathers: the substance (ousia) in the Godhead is akin to secondary substance, which constitutes the common nature of the three particulars (hypostases), Father, Son, and Holy Spirit." p. 335). Moreover, he cites historical examples from the Cappadocian Fathers using this terminology in describing the Trinity.
I am aware that in the East, the Fathers were more at ease in starting with the Three-ness of God (as opposed to the West starting with the One-ness), but is this way of describing the Trinity problematic? The author counters the Tritheism charge by appealing to the perichoresis of God since God is not in space as we are, but is rather a spirit.
