Quit pretending to mix Christianity and Judaism and call the resulting Adventist rendition 'christianity' when it is a synthesis that is no longer either. Adventist dependence on the old covenant for its soteriology was already shown to you by the Pen of Liability:

Chapter Title: No Probation After Christ Comes
As we have followed down the chain of prophecy, revealed truth for our time has been clearly seen and explained. We are accountable for the privileges that we enjoy and for the light that shines upon our pathway. Those who lived in past generations were accountable for the light which was permitted to shine upon them. Their minds were exercised in regard to different points of Scripture which tested them. But they did not understand the truths which we do. They were not responsible for the light which they did not have. They had the Bible, as we have; but the time for the unfolding of special truth in relation to the closing scenes of this earth's history is during the last generations that shall live upon the earth. Special truths have been adapted to the conditions of the generations as they have existed. The present truth, which is a test to the people of this generation, was not a test to the people of generations far back. If the light which now shines upon us in regard to the Sabbath of the fourth commandment had been given to the generations in the past, God would have held them accountable for that light. When the temple of God was opened in heaven, John saw in holy vision a class of people whose attention was arrested and who were looking with reverential awe at the ark, which contained the law of God. The special test upon the fourth commandment did not come until after the temple of God was opened in heaven. Those who died before the light was given upon the law of God and the claims of the fourth commandment were not guilty of the sin of violating the seventh-day Sabbath. The wisdom and mercy of God in dispensing light and knowledge at the proper time, as the people need it, is unsearchable. Previous to His coming to judge the world in righteousness, He sends forth a warning to arouse the people and call their attention to their neglect of the fourth commandment, that they may be enlightened, and may repent of their transgression of His law, and prove their allegiance to the great Lawgiver. He has made provision that all may be holy and happy if they choose. Sufficient light has been given to this generation, that we may learn what our duties and privileges are, and enjoy the precious and solemn truths in their simplicity and power.
To show Ellen's dependence on 1844, I will include this quote from Early Writings, Pg 42-43:
Sabbath, March 24, 1849, we had a sweet and very interesting meeting with the brethren at Topsham, Maine. The Holy Ghost was poured out upon us, and I was taken off in the Spirit to the city of the living God. Then I was shown that the commandments of God and the testimony of Jesus Christ relating to the shut door could not be separated, and that the time for the commandments of God to shine out with all their importance, and for God’s people to be tried on the Sabbath truth, was when the door was opened in the most holy place in the heavenly sanctuary, where the ark is, in which are contained the ten commandments. This door was not opened until the mediation of Jesus was finished in the holy place of the sanctuary in 1844. Then Jesus rose up and shut the door of the holy place, and opened the door into the most holy, and passed within the second veil, where He now stands by the ark, and where the faith of Israel now reaches.
I saw that Jesus had shut the door of the holy place, and no man can open it; and that He had opened the door into the most holy, and no man can shut it (Revelation 3:7, 8); [see page 86. See also appendix.] and that since Jesus has opened the door into the most holy place, which contains the ark, the commandments have been shining out to God’s people, and they are being tested on the Sabbath question.
I saw that the present test on the Sabbath could not come until the mediation of Jesus in the holy place was finished and He had passed within the second veil; therefore Christians who fell asleep before the door was opened into the most holy, when the midnight cry was finished, at the seventh month, 1844, and who had not kept the true Sabbath, now rest in hope; for they had not the light and the test on the Sabbath which we now have since that door was opened. I saw that Satan was tempting some of God’s people on this point. Because so many good Christians have fallen asleep in the triumphs of faith and have not kept the true Sabbath, they were doubting about its being a test for us now.
Ellen White's soteriology revolves around the Sabbath she failed to keep Holy according the Law that ordained it. This is evident in these quotes provided below that show the Adventist formula for 'salvation' to be compliance with the old covenant from Mount Sinai you don't acknowledge God's redemption from:
No one is saved who is a transgressor of the law of God, which is the foundation of his government in heaven and in earth. {RH June 17, 1890, par. 8}
It means eternal salvation to keep the Sabbath holy unto the Lord. God says: "Them that honor Me I will honor." 1 Samuel 2:30. {6T 356.4}
But if we turn aside from the fourth commandment, so positively given by God, to adopt the inventions of Satan, voiced and acted by men under his control, we cannot be saved. We cannot with safety receive his traditions and subtleties as truth. {RH, July 6, 1897 par. 4}
No one who disregards the fourth commandment, after becoming enlightened in regard to the claims of the Sabbath, can be held guiltless in the sight of God. {RH, July 6, 1897 par. 14}
All will be judged according to the light that has shone upon them. If they have light upon the Sabbath, they cannot be saved in rejecting that light.{HS 234.3}
As persons become convinced from the Scriptures that the claims of the fourth commandment are still binding, the question is often raised, Is it necessary in order to secure salvation that we keep the Sabbath? This is a question of grave importance. If the light has shone from the word of God, if the message has been presented to men, as it was to Pharaoh, and they refuse to heed that message, if they reject the light, they refuse to obey God, and cannot be saved in their disobedience. {RH, January 5, 1886 par. 2}
“God requires of all His subjects obedience, entire obedience to all His commandments. He demands now as ever perfect righteousness as the only title to heaven. Christ is our hope and our refuge. His righteousness is imputed only to the obedient!” (Review & Herald, Sept. 21, 1886)
"Christ does not lessen the claims of the law. In unmistakable language He presents obedience to it as the condition of eternal life—the same condition that was required of Adam before his Fall. The Lord expects no less of the soul now than He expected of man in Paradise, perfect obedience, unblemished righteousness. The requirement under the covenant of grace is just as broad as the requirement made in Eden—harmony with God’s law, which is holy, just, and good." (Christ’s Object Lessons, p. 391)
How much clearer does it need to be that the SDA church adopts a formula of 'salvation' by compliance to the old covenant? This is not a Christian organization that recognizes God's redemption from the covenant from Mount Sinai, and having one foot in the tenets of Judaism while giving lipservice to our Redeemer is their form of promoting adultery.
Therefore, my brethren, you also have become dead to the law through the body of Christ, that you may be married to another—to Him who was raised from the dead, that we should bear fruit to God.
