What soaps are you watching?? From what I've been able to discern, unless it's a Latino, Irish, or Italian family, most everyone seems to be some form of Protestant.... Except, of course, for the occasional Jew.....
I watch Days and Passions. On Days the Bradys are Irish, but everyone else on the show are Catholic too including the Kiriakis who are Greek.. The Horton's who are the original family on the show are Catholic. That could be to have made it easier for their daughter to become a nun after she found out she was having an affair with her brother, LOL. On Passions the Lopez-Fitzgeralds are Irish and Mexican but the Cranes, Bennets, Russels are who knows what. All go th the same church. The only non Catholics on the show seem to be Tabitha and Endora who I guess are Wiccan?
I only watched Passions for a couple of seasons way back in 1999 to 2000 or so). I, too, was shocked that everybody (sans Tabby, Timmy and another witch I can't recall) were Catholic, even though the show took place in NE and some of the flashbacks indicated that most people descended from the Puritans! Hello!!
I was told that the creator of the show (Reilly?) is Catholic, hence the religious orientation for the soap.
I'm trying to figure out how Pine Valley has a beach nearby that everyone was hanging out at for a while (this would have been the beach that Dmitri got washed up on a few years ago, and Hayley and Mateo's "special place"), when Pennsylvania is a landlocked state.....
