In the beginning of S2E4, titled Evil Spirits in Heavenly Places, Ethan has insisted that Vanessa tell the others her story about the Cut-Wife, and that they are fighting against Nightcomers. Ethan quotes a rendition of Ephesian 6:12. He says:
“For thee are not fighting against flesh and blood enemies, but against mighty powers in this dark realm”
Then Vanessa finishes the verse, saying:
“And against evil spirits in Heavenly places”
However, the actual verse from Ephesian 6:12 is:
“For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.”
