The Druidical opinion of God

While there are the Brittish 1800's  Patriarchal Male Christian stains, required by all of the times, still it is quite an interesting and enlightened view, given claim of the Druids.
TDK

"There is a bold and remarkable
saying which comprehends in very few
words the Druidical opinion of God. It
cannot be translated so as to convey its
force and beauty, but still we can gain
its meaning tolerably well.

"Nid Dim Ond Dew, Nid Dew Ond Dim"

(Welsh ?)

i.e., " God cannot be matter ; what
is not matter must be God."

These were the attributes of the God of the early Druids,
and they believed that the Deity was the Source of life and Giver
of good; they defined His duration as eternal, and believed that there was no
limit to His power.

As this was published in 1881, I expect this was its roots:

"Nid dim oxd duw: nid duw ond dim." 

God cannot be matter; what is not matter must be God."
Ref. The Veil Of Isis; Or, Mysteries Of The Druids By W. Winwood Reade (1861).

Note the difference in spelling also.
