Even the proofs imply a reductionist account no? The first proof says: the table holds up the glass, the floor holds up the table and the earth holds up the table. And then asks, what holds up it all? Answer: necessarily God. But then God is at the edge (first) of this causal chain and the table is still holding up the glass (directly), no? And God is holding up the universe (directly) and everything in it (indirectly). Thus, saying that God is holding up the glass would be misusing the usual meaning of the term "holding up".
