Brother Blaine,
I will tell you this short story, which is typical when I encounter SDA.
I had 2 friends that invited me to a "Bible Study", who I knew well and whom I trusted. We went to the Bible study, and I immediately found out that if you attended the study, you earned points, and the more people you brought, the more points you earned, until you could purchase things like ipads, computers, trinkets, etc. Red Flag.
So they started teaching about the end. I guess they were trying to convince people that the end was upon us and that we needed to do something about it. Their apocalyptic timeline was very skewed, and the means by which a person was saved was REALLY unclear. It floated between grace and works, and likely, just depended upon whatever the hearer could decipher out of the mess. They largely read out of Ellen G. White materials rather than the Bible. Also red flag.
So I got up and left and took my 2 friends with me.
I have encountered several SDA people, and ALL of them carried legalistic baggage with them--Sabbath keeping, no meat, etc.
