This is the official Adventist position! The above doctrine means that all SDA members must comply with ALL of the requirements of the SDA church to be saved. So, according to SDA doctrine, if you don't tithe, you're not saved. Jesus NEVER asked anyone to FOLLOW Him to be saved; BUT, rather, only to BELIEVE upon Him (John 3:16). Jesus never asked anyone to work for salvation, only believe.
Although I am not an SDA and don't agree with some of their doctrines, I do believe that you are making an errant statement here...
Christ never, ever taught that salvation could be earned by works, yet He did teach obedience to the Law...
Mat 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Mat 5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Mat 5:19
Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
Mat 19:17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
John the Baptist was the greatest of human beings...
Mat 11:11 Verily I say unto you, Among them that are born of women there hath not risen a greater than John the Baptist: notwithstanding he that is least in the kingdom of heaven is greater than he.
John prepared the way for Christ how? By telling everyone to believe Him who was coming?
Mat 3:2 And saying,
Repent ye: for the kingdom of heaven is at hand.
Mat 3:3 For this is he that was spoken of by the prophet Esaias, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
Mat 3:8 Bring forth therefore
fruits meet for repentance:
Also the Apostle Peter taught this...
Act_2:38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
Act_3:19 Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord;
John admonishes us...
Jas 2:19 Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
Jas 2:20 But wilt thou know, O vain man, that faith without works is dead?
Yep, the demons believe and tremble, but they will not willingly obey.
