Without the Ten Commandments then there are no standards. None. It really comes down to this point. God's Ten Commandments are the ultimate revelation of His character and His nature. Without the Ten Commandments then there are no standards necessary to teach anything.
"And shall anybody advocate that the Lord of the universe has no law to govern His kingdom? Is it the doctrine of Jesus Christ or of heaven that the law of God has no binding claims upon the world's inhabitants? Why, the law of ten commandments is the great moral standard of righteousness in heaven and upon earth. This great law is the foundation of all laws, to all nations, and to all families." - Ellen White, Christ Triumphant
"In answer to the claim that at the death of Christ the precepts of the decalogue had been abolished with the ceremonial law, Wesley said: "The moral law, contained in the ten commandments, and enforced by the prophets, he did not take away. It was not the design of his coming to revoke any part of this. This is a law which never can be broken, which ‘stands fast as the faithful witness in Heaven.' . . . This was from the beginning of the world, being `written not on tables of stone,' but on the hearts of all the children of men, when they came out of the hands of the Creator. And, however the letters once written by the finger of God are now in a great measure defaced by sin, yet can they not wholly be blotted out, while we have any consciousness of good and evil. Every part of this law must remain in force upon all mankind, and in all ages; as not depending either on time or place, or any other circumstances liable to change, but on the nature of God, and the nature of man, and their unchangeable relation to each other." - Ellen White, The Great Controversy
"The law of the ten commandments, given in awful grandeur from Sinai, can never be repealed while the heavens and the earth remain. All enlightened law and government had its origin in those ten words of the Almighty. Those who speak slightingly of the moral code are blinded by sin, and are on the side of the great rebel, who has ever been at war with the law of God which is the foundation of his government in heaven and on earth. When God issues a proclamation that men are guiltless if they cease to love him, to reverence his name, and to keep holy his Sabbath--then, and not till then will the law of God be abrogated." - Ellen White, The Signs of the Times, March 7, 1878
