All my extended family is catholic but the in-laws were nutty evangelicals. They truly believed the earth was 6000 years old, dinosaur bones were from dragons, the works. Nearly every gathering with them involved pointless bible debates that went nowhere for hours. Meanwhile the catholic family members never discussed religion but there'd be prayers at every meal and iconography everywhere. I guess it was taken for granted we were all on the same page, and figuring out doctrine was the priest's job.
