The SDA church is a cult and it gives the same credence to Ellen White's teachings as it does to the Bible and Scripture. For those of you not familiar with Ellen White, she was originally a member of the Millerite movement who numerously and erroneously predicted the end of the world. When the cultist Millerite movement collapsed, White picked up the banner and co founded the SDA Church. The SDA Church regards White as a prophet, even though almost all of White's prophesies proved to be false. Ellen White's teachings are anti biblical and her prophecies turned out to be false. A real prophet of God does not give false teaching or prophesies: Ellen G. White–False Prophetess – Truediscipleship
It's no longer considered a cult because they ascribe to all the main tenants of the faith. They are no more a cult than churches that follow John Calvin or John Darby or believe in and teach false doctrine--which ALL denominations do. Non-denominations leave what they believe vague to gather more customers.. er...congregants. The reason I wouldn't attend a 7th day Adventist church is because they emphasize the Sabbath as if it is a point of faith--in a legalistic way--and of course because they have not denounced Ellen White as a false prophet.
