These are the greatest and most fundamental errors of Seventh-day Adventists:
1. Seventh-day Adventists don't care about the rights of victims, justice or free speech, unless Satan's unrestrained power of evil impacts their own personal right to keep the Sabbath.
2. Seventh-day Adventists are fanatically obsessed with their belief about their own suffering in the future and don’t care about how their indifference contributes to the suffering of others now.
3. Their souls delight in their abominations.
I might have agreed with you had you preceded your statements with "Some". I believe there are many SDAs that would give up their lives for their fellow man just as Jesus did for you and me.
The fundamental errors errors of SDAs are that the Sabbath is a salvational issue, the IJ, that somehow the old covenant 10 commandments are Christians guide to a righteous life and their false interpretation of James concerning works.
They also add to scripture by believing they had a prophet that was able to interpret scripture. One blatant error is adding a 10 before commandments in the New Testament. Then they have a guy by the name of Blanco that took upon himself to change the "errors" in the Bible with Ellen's interpretations making it so convenient for the brethren to know the "truth"
