This is off-topic for this thread. If you're not interested in working for the company or don't think it would be a good fit for whatever reason, just don't apply. Same as someone calling out a tech stack they don't like: it's just what the Who is hiring? threads are for.
This is only 1 step removed from "We prefer only $religion here." Or another way to look at it, is "We dont like $your_religion." They aren't out-right saying that, but the dog-whistles are most certainly there, biblical quotes and all.
I would understand if the organization was a church or religious group. But it seems to be pretty bog-standard tech shop. It, at absolute minimum, is a warning sign of potential religious discrimination. To put it bluntly, unless there's a religious component in the nature of the job, the very fact that religion is mentioned on their pages is at best off-topic, a warning sign to all, and at worst a potential sign of EEOC violations.
If the legality is what concerns you, fair enough, though I do think you're overreacting without further evidence. People are perfectly capable of holding beliefs and hire and work with people who share others. However, that is not how you presented it or are discussing further.
