Yeah, I also agree about Sunday worship. But I don’t think Protestants have a particular sabbath day, either. Is the Adventist faith considered Protestant, because you said it used to be anti-Catholic. But I think at the end of the day, the differences among most Christian sects don’t differ radically enough to affect salvation; as long as they don’t have an allegedly-“infallible” leader, like the ones that Roman Papists, Greek Papists, and Anglican Papists have. And stating that just raised another question: If the Roman Popery is the Antichrist (making the RCC Satanic and not Christian), are the Greek & Anglican Papists Satanic, Christian, or their own category of pagan, pseudo-Christian idolaters?
