SDA are not a cult. I suggest you look up the meaning of the word
Dear Laodicea: Why aren't SDA a cult? How do you know that they aren't? Should we have an open mind and be open to the possibility that the Seventh Day Adventists are a cult based on the physical illness (epilepsy/brain damage) of Ellen G. White?
