Adventist teaching: Yes
Biblical teaching: Not stated
Ellen G. White, who the SDA Church upholds as divinely inspired and correcting of inaccurate interpretations of scripture, claimed that God showed her other worlds He created where He reproduced the pattern found in Eden—namely, a Tree of Life and a Tree of Knowledge of Good and Evil. These worlds observe the 10 Commandments and have never fallen into sin like humanity has and, in the great controversy, they all watch in on the earth like a stage as the controversy between Christ and Satan rages on.
The Bible says nothing of the sort nor is there any reason to believe that God showed her this and allowed her to converse with these beings on these other worlds. This is what we call an “Advent-ism.”
