What is it that SDA do believe if it is not the rapture?
go through the great tribulation. In fact, they look forward to it! They believe that they will be the last voice for God during that time, and some believe that they will be sinless (Rev 14:5) during this time. They also believe that the mark of the Beast (Sunday, as they see it) will be fully initiated into law, where everyone will be forced to worship on that day. This is where they will say that the “tribulation” will be most heavy upon them (SDA) because Rome will kill many of them for their stance on Saturday worshiping.
