Now, according to the Bible a saint is a saint is a saint. Unless you have Roman Catholic tendencies there is no difference between a "tribulation saint" and a non-tribulation saint. They are all part of Christ's church, His chosen people, His "holy nation", His "royal priesthood".Catholics believe that "a saint is a saint is a saint" too. We honor all the Saints in Heaven, declared and undeclared, on All Saint's Day.
