I know, I know: three thumbs-up for a comment is unrealistic, since, who has three hands? But then, I thought: Why not? -- since only two thumbs-up doesn't seem quite adequate for extolling the truth of your comment, and since having three hands is scarcely more unrealistic than having two left hands!
You're exactly right: "the substance that IS Them"!
If you've glanced at my posts, you may have noticed that I like the standard Trinity diagram pretty well:
As I imagine you already know, these twelve truths are nicely presented by that simple -- and I say, beautiful -- work of art:
- God is the Father.
- God is the Son.
- God is the Holy Spirit.
- The Father is God.
- The Son is God.
- The Holy Spirit is God.
- The Father is not the Son.
- The Father is not the Holy Spirit.
- The Son is not the Father.
- The Son is not the Holy Spirit.
- The Holy Spirit is not the Father.
- The Holy Spirit is not the Son.
It's so easy to see that no contradiction is involved between any of those twelve propositions. You could replace the label 'God' in the center of the triangle with, say, the label 'Water'; and replace the 'The Father', 'The Son', and 'The Holy Spirit' labels on the vertices with, say, the labels 'The Atlantic Ocean', 'The Pacific Ocean', and 'The Indian Ocean'; and thereby a nice Trinity analogy is presented in twelve obvious truths about water and three of its bodies. (And, the fact that God is three Persons, whereas water is far more than three bodies, is irrelevant to, and of no militance against the fact of the analogy.)
- Water is the Atlantic Ocean.
- Water is the Pacific Ocean.
- Water is the Indian Ocean.
- The Atlantic Ocean is water.
- The Pacific Ocean is water.
- The Indian Ocean is water.
- The Atlantic Ocean is not the Pacific Ocean.
- The Atlantic Ocean is not the Indian Ocean.
- The Pacific Ocean is not the Atlantic Ocean.
- The Pacific Ocean is not the Indian Ocean.
- The Indian Ocean is not the Atlantic Ocean.
- The Indian Ocean is not the Pacific Ocean.
