Retreating into pious nonsense

I'll comment on this post:

God is in time because there is no time unless God is in it.

Unfortunately, Shannon gives the reader no reason to agree with that claim, on its own terms. It's just a tendentious slogan. 

At best, he shifts gears to a different argument:

That’s a little Vos-Van Til talk, but we could infer the same from omnipresence and eternity. Eternity does not mean that God as God cannot touch temporality (again, unless you are entangled in Thomistic simplicism; but then you have created your own problems). It means that he fills all time, just as omnipresence doesn’t mean that God cannot be in places (spatially located); it means that he fills all places. This is an unbiblical non sequitur: He fills all time, therefore he cannot be in time. So is this: He fills all space, therefore he cannot be in a place.

It doesn't even occur to Shannon that his comparison might backfire: just as omnipresence doesn't mean God literally fills space, eternity doesn't mean God literally fills time. Shannon doesn't anticipate that move, or give the reader reason to deny it. 

So if we affirm, say, omnipresence, what then is condescension (which the divines worked into the confession—WCF 7.1)? If God fills all space, what does it mean that he ‘comes down’? To where does he come down? Well, to the top of Mt. Sinai (Ex 19), for example—even though being omnipresent, he was already there. He ‘comes down’ to covenant with Israel. Mt. Sinai is a particular place; and Ex 19 records the Lord’s presence there at a particular time. And so: if God fills all time, we may say that he condescends in order to covenant with his people at Mt. Sinai, at that time. The Lord speaks to Moses, then and there. 

That's a theophany or angelophany. A manifestation of God's presence. A manifestation is the effect of something else, and not the thing itself. 

Take a hologram. I could see and hear your holographic presence in my living room, but that doesn't mean you are physically present in my living room. It's a concrete representation. 

In principle, I might be dead by the time you receive the hologram. In that event, not only am I not actually in your living room, I'm not even offsite. 

And this presence of God with his people is no innovation; it is the telos of covenant history:

“Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God.” Rev 21:3 

That presumably alludes to Christ dwelling with his people. That involves the communication of attributes. The usual Reformed construction is that what's said of each nature can be said of the person, but what's said of one nature can't be said of the other.
