I get it that these "Church Ladies" have their Christian beliefs and may possibly not cohabitate outside of marriage themselves. These are probably the same Church Ladies that walk 10 paces behind their husbands and their place is in the kitchen, too. But thumping their bible against your head and being judgemental sure isn't very Christian-like. I would simply address it as "Thank you for your concern, but this is my choice to make" and leave it at that. If it were me, I probably wouldn't be able to suppress a "judgemental much?" comment, though.
