@Elhao: Yes and no.
What he picked up was a statue of a goddess long forgotten, where the king of God made it so his prayer upon said statue would count for praying to Altena, and over time she became a real goddess.
Although with that said, I wonder if that's actually Noir's statue....it would make a bit more sense on why Noir awakened at the same time as Altena's return (they're both getting his prayers) and also why Noir was heading there in the first place (she felt a 'kindness' coming from that direction amongst all the prayers born of hatred and sought it seeking help)
Going back to it, here's Noir's statue as worshipped by the monsters.

EDIT: Hmm the one on this page https://mangadex.org/chapter/887198/30 is a bit different though...
