It can look convincing in a superficial approach but does not resist in my opinion a deeper analyses.
Comparing phraseology common to Celtic religions and to the Bible is not concluding enough as one of the main subject of almost if not all religions was the contrast between the ephemerity of Man's life and the Eternity of the Everlasting (at least before the Human eyes) , invisible and Unknown forces that rule the Universe; the dychotomy between the visible world, things that we know, we understand and we can see and Those which go beyond our understanding, those we do not see but we feel that are somewhere there; those which are part of the "Great Mistery".
Human beings, whatever was their race culture, time and place always had their concept of "good" an "evil" and that there was an invisible hand or hands that provided them with the good things and another /anothers who sent them the bad ones.
So there's no wonder that we might find adjectives such as "Invisible one" , "distributor", "Eternal" etc in religions that are not connected.
