I guess that is not intentional. Some time ago, I don't remember when, Joseph Fink and Jeffrey Cranor opened submissions for the weather and they said that thay would just take all the songs they like and not necessarily the weirdest ones.
And because most of (today's) songs are either about relationships/love/sex or life/death and religion is connected to at least one of those and often used as a metaphor for the other one it should be unavoidible to have religious content in the weather.
(But it is funny you mention this because the (MIGHTY) glow cloud (ALL HAIL) is a god, according to Huntokar. And in our world, clouds are basically the symbol for weather. So there is religion in the weather.
Even if this is just a ridiculous association.)
