to practice Catholicism in any traditional sense
Between Scotland and North Carolina it was pretty much impossible to “go to church” or however we would define traditional Catholic practices. Catholicism was outlawed in most of the 13 colonies, though your best best was Maryland. Since Catholics need a priest to act as an intercede /mediate with God then without a priest there can’t be many of those ‘traditional practices’.
(I’m decidedly not spiritual, so I don’t have anything to add to that part of the discussion.)
