Hi barry, Walter Martin held the view they were cults before his period of rest in a SDA hospital (Psyche was the rumors) Currently Ravvi Zaccarias who was a co-author or updated author with "Kingdom of the Cults" hold the view "SAD are a cult religion. S.A.D. jumped at the chance to have Walter Martin (It's in debate whether Walter's Doctorates are Kosher) do an about face in 1965 that considered them Christian. To date, there are many members of Fundamental Christianity who consider them a cult.
"
The Seventh-Day Adventists are an anomaly. Evangelical Christians have never been comfortable with them, but they have been unable to decide whether the SDA is a legitimate expression of Christianity or whether it is a cult, like the Mormons and Jehovah's Witnesses.
The majority view among contemporary cult-watchers is that it is a cult. But the most authoritative cult expert in modern Christian history, Dr. Walter Martin (1928-1989), decided in 1965 that "it is perfectly possible to be a Seventh-Day Adventist and be a true follower of Jesus Christ, despite heterodox concepts." 1 This conclusion caused a storm of controversy because Dr. Martin had earlier labeled the SDA a cult in his book published in 1955 called The Rise of the Cults. 2
Yet, shortly before he died, Dr. Martin expressed conflicted second thoughts in a television interview:
"I fear that if they continue to progress at this rate, then the classification of a cult can't possibly miss being reapplied to Seventh-Day Adventists because once you have an interpreter of Scripture, a final court of appeal that tells you what Scripture means - as soon as you judge Scripture by that, as soon as you have someone who has made doctrinal errors in the past, even on the deity of Christ and the doctrine of the atonement and on other things, and that person is raised to that position of authority, you have polarization around that person." 3
If Christendom's foremost cult expert could not make up his mind about the status of the SDA, you can certainly understand why others have experienced equal difficulty. So, what about it? Does the SDA deserve the designation of a cult?

This next link is not so kind to the SAD, in his writings Martin made a mistake, other apologist think Walter Martin had a nervous break-down and went to a S.A.D. convelence home, and was brain-washed (a rumor I heard in the 1980s) of Martin's straying from his Fundie allies. What is the real truth, and why Walter Martin created some type of alliance with the SDA has baffled apologist in the 1960s until now. Oh, how I love conspiracy theories dealing with religion. Peace Barry!
