The name references the Pilgrim Fathers of america - they openly and publicly wanted to build a ‘city on a hill’ to be ‘shining example of holiness’ to the rest of the world. They both started and ended up as religious extremists of very nearly the worst possible description. Check out the Salem witch trials. Yeeesssss, the cultishness risk is present and def should be guarded against imo. I hope she’s OK too. She might see through the jargon to the very present risk of woman control/subjugation in the name of holiness.

Still, as Terry Pratchett puts it, slavery is a wonderful refuge from uncertainty. Maybe she’s feeling in need of some certainty in her life. Or maybe anxiety relief. Which is reasonable given the chaotic nature of modern times. I do think that joining a church with a history of very prescriptive behaviour for women is is NOT the best possible way to relieve anxiety about her life choices though. Best you can do imo is to be present but not judgmental about her choices. As stated before, she may well see through the bullshit and make better choices in the future.
