What defines a cult is their teaching concerning Christ. All cults diminish Jesus in some way. Jehovah’s Witnesses and SDA’s teach that Jesus and Michael the Archangel are the same.
Who told you that. I read a lot about SDA in Bible School, and I never found anything like that. In fact, they do teach about Jesus, and I couldn’t find anything about them diminishing Jesus anywhere in their prepared statements.
Maybe one of their churches taught that .. but it’s not anywhere in the founding documents.
So, I don’t know where you got your information .. but maybe you better do some more research .. because it appears to be way to far off target to be real.
And, I still do not believe SDA is a cult. In order to define it as a cult, there are many, many criteria that the SDA does not do .. so therefore, they cannot be classified as a “cult”.
