To clarify, I can see at least three elements that seem to be more in line with Eastern theilogy than Western which is what got me thinking:
1) Apophatic statements about God: immortal, invisible, unresting, unhasting, unchanging ("naught changest thee"), not in want, not wasting etc.
2) The idea that God dwells in unapproachable Light - a Divine Light
3) God dwelling in all - the so-called "panentheism"
It makes me interested to know more about the hymn writers background. Any other similarities?
