Since God is an incorporeal and unchangeable living nature, remaining in eternal stability in his own self, he is entirely present in all things, and entirely in each of them. But those in whom he dwells receive him according to the diversity of their capacity, some more, some less, whom he builds into a temple most beloved to himself by the grace of his goodness.Epistola 187, c6 n19
When we speak of God's presence, we are not, of course, speaking of a physical presence, for God is incorporeal. What we mean, rather, is that he is able to act on and in the creation and to evaluate authoritatively all that is happening in the creation. Since God controls and evaluates all things, he is therefore present everywhere, as present as an incorporeal being can be. But in this chapter, we are interested in something more than mere presence. For God is not only present in the world; he is covenantally present. He is with his creatures to bless and to judge in terms of the standards of his covenant.Systematic Theology: An Introduction to Christian Belief (Kindle Locations 1778-1783). P&R Publishing.

The veil's separation function was executed by its prohibition of physical and visual accessibility to God. If this function ceases at the velum scissum, then the barrier that prohibits one from physically entering the presence of God, as well as from seeing his face, is effectively removed (again, as a result of the death of Jesus)The Torn Veil, Cambridge University Press, 2007, 189
God is indeed, a God afar off; but He approaches you by and in the Scripture; unveils His presence to you; and speaks to you as though you were standing right by Him, and He drew you close beneath His wings.Principles of Sacred Theology, 364
