What About Seventh-day Adventists?

The Seventh-day Adventist Church was founded in the 1850's by Ellen G. White (1827-1915).  White combined the teaching of the Millerites who predicted the return of Christ would take place in 1844 and the Seventh-day Sabbatarians.  Some Christian apologists consider Seventh-day Adventists a Christian denomination with errors while others consider it a cult or false religion.  

In its official teaching the SDA affirm the authority of the Bible and the doctrine of the Trinity.  They affirm the deity of Christ, the virgin birth, he was sinless, his death on the cross, and resurrection.  But there have been some within the SDA movement who have deviated from these core beliefs.  

The Seventh-day Adventists believe that Christianity was corrupted in the early centuries by Roman Catholic popes.  They believe the Catholic Church changed the Sabbath day from Saturday to Sunday.  SDA believe that a Remnant church has existed throughout history worshiping on Saturday.  The SDA believe that worship must be on Saturday and see it as the seal of God.  Those who worship on Sunday will receive the mark of the beast.  We might point out that the New Testament church met on the first day of the week (Sunday) because of the resurrection of Christ.  

Seventh-day Adventists also add works to salvation.  They see observance of the seventh-day sabbath as necessary for assurance of salvation.  SDA believe that in 1844 Jesus began the second phase of his atoning ministry called the "investigative judgment".  In it Jesus examines the dead to see if they are true believers and examines the living to see if they are in Christ and obeying his commandments.  SDA believe in soul sleep until the resurrection and believe that hell is not eternal but that unbelievers will be annihilated.   

Ellen G. White the founder of the Seventh-day Adventists supposedly possessed the "spirit of prophecy".  SDA believe her visions were the divine interpretation of Scripture.  White is seen as the final end time prophet. 

It seems that nearly half of Ellen G. White's writings were borrowed from other people.   Ellen G. White was a false prophet who was deceived and taught a false gospel.  SDA believe that all who worship on Sunday as the New Testament church did will receive the mark of the beast, while those in the SDA Church who worship on Saturday will be saved. Much of the Seventh-day Adventists teaching is based on an erroneous interpretation of Revelation 14:6-12.  

Based on the standard set down by the Apostle Paul in Galatians the Seventh-day Adventists teach another gospel (See Galatians 1:8-9).  They do not hold to the gospel of justification by faith alone in Christ alone.  While there may be some SDA who are true Christians it is simply not Biblical Christianity.
