If persons are relations of a simple essence,
* How does such a relation become incarnate?
* Does this relation have a relation to the human nature?
* If two (or three) of the persons are relations, then are there relations between the relations? How does this not entail gnosticism with its endlessly multiplied hypostases?
I suppose one could get around this by saying that the term “relation” takes on a different meaning (albeit with no warning).
