Do Seventh Day Adventists believe people who attend church on Sunday will go to hell? My children attend a Seventh Day Adventist school. One teacher often mentions that 'people who go to church on Sunday will go to hell'. Is this consistent with Seventh Day Adventist belief?
Do Seventh Day adventists believe that people who go to church on Sunday will go to hell?

No we do not, we believe only those who are unfaithful to God will be not be in heaven. 

The Bible is clear that God has His people in many denominations. In Revelation 18:4, a voice is heard in heaven saying:


  "Come out of her, my people, lest you share in her sins, and lest you receive of her plagues." (Revelation 18:4)


There is also a common misconception that we believe Sunday keeping is the mark of the beast. But it is not. Only when Sunday keeping is a forced day of worship, restricting freedom of conscience, do we consider it the mark of the beast. The writings of Ellen White in SDA Bible commentary explains:


  "Sundaykeeping is not yet the mark of the beast, and will not be until the decree goes forth causing men to worship this idol sabbath. The time will come when this day will be the test, but that time has not come yet." The S.D.A. Bible Commentary 7:977 (1899). 


However, this is not to say that the Sabbath is not a test today, because it is. True observance of the fourth commandment is an outward sign of loyalty to God, just like the rest of the ten. Only that we are not able to say who has received this light and who has not.


  "We shall not be held accountable for the light that has not reached our perception, but for that which we have resisted and refused. A man could not apprehend the truth which had never been presented to him, and therefore could not be condemned for light he had never had."—The S.D.A. Bible Commentary 5:1145 (1893).


The truth is Adventists within the same denomination will differ in their conviction of how much/ to how many God has revealed this light to today. Many have grandparents or relatives in Sunday churches, so it is a sensitive issue. More liberal Adventists believe that unless you are 100% convinced, you are perfectly fine to attend Sunday keeping churches. However, more conservative Adventists believe that many Sunday goers have heard of the Sabbath, but have neglected to study further and have quietened their conscience to a degree in breaking this commandment in favour of tradition, and thus will be held accountable. 

Either way, what we do agree on is that no one is really saved by keeping Sunday or Sabbath, but by our faithfulness to Jesus and willingness to follow the lamb wherever He goes (Revelation 14:4). We will see many Sunday goers in heaven, especially those who lived in the middle ages when the Sabbath truth was lost to many.
