...that Orthodox and protestants are saved, too, if they're not in mortal sin, that is, if being schismatic and manifesting such heresy is not a mortal sin, and they believe in Christ, and serve and love Him? Or does the SSPX teach Extra Ecclesiam Nulla Salus applies strictly to Catholics, only, who are in communion with the Chair of Peter (whether vacant or filled)?
So in other words, if the Oriental/Eastern Orthodox and protestants are not considered to be a part of the Catholic Church, even imperfectly as it would be, its members will be damned even if they do their best in living a holy life and following Christ? Please, only answer if you're SSPX, or attend a SSPX chapel and you're are knowledgeable with this dogma.
