You are in unbelievable denial. You are committing, AND TEACHING, lawlessness.
Mat 24:3 And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world?
Mat 24:15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:)
Mat 24:16 Then let them which be in Judaea flee into the mountains:
Mat 24:17 Let him which is on the housetop not come down to take any thing out of his house:
Mat 24:18 Neither let him which is in the field return back to take his clothes.
Mat 24:19 And woe unto them that are with child, and to them that give suck in those days!
Mat 24:20 But pray ye that your flight be not in the winter, NEITHER ON THE SABBATH DAY:
Note that Jesus was speaking to His disciples. There are two possible applications of the above text. The first is the destruction of Jerusalem in 70 A.D. by the armies of Rome. Note the parallel text in Luke to verse 15:
Luke 21:20 And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.
This verse makes clear that Jesus is warning His disciples of the impending destruction of Jerusalem, and that they should pray that they will not need to flee on the Sabbath. Why would that matter? Jesus as God intended the sabbath day to be one of rest and spiritual growth, not a day of panic; fleeing from a invading army of persecutors. Jesus is affirming here, that 40 years after His death on the cross, the Sabbath would still be observed by His disciples.
Many Christians today, while they might acknowledge an initial application of Matthew 24:15-20 to the Roman destruction of Jerusalem, will also maintain that this passage applies most fully to an event yet future. They believe that the antichrist will desecrate the temple at some future date, and that this will signal the nearness of the second coming. If one subscribes to this future timing, then Jesus is speaking of His disciples observing the Saturday seventh day Sabbath all the way into a time that is even now still in the future!
Not only was the Sabbath never rescinded, but scripture even makes clear that in the future, all of mankind (those who are saved) will observe the Sabbath when worshipping the Lord:
Isa 66:22 (KJV) For as the new heavens and the new earth, which I will make, shall remain before me, saith the LORD, so shall your seed and your name remain.
Isa 66:23 (KJV) And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD.
Other problematic doctrines in Seventh-day Adventism include the teaching that Satan is the “scapegoat” and will bear believers’ sins (The Great Controversy, p. 422, 485)—this is the opposite of what the Bible says about who bore our sins (1 Peter 2:24). Seventh-day Adventism also identifies Jesus as Michael the archangel (Jude 1:9, Clear Word Bible, published by Review and Herald Publishing Association, 1994)—a doctrine that denies the true nature of Christ—and teaches that Jesus entered a second phase of His redemptive work on October 22, 1844, as prophesied by Hiram Edson. And, of course, the Adventist promotion of Sabbath-keeping as a primary doctrine goes against the teaching of Scripture on the matter (see Romans 14:5).
Seventh-Day Adventism is a diverse movement, and not all SDA groups hold to all the doctrines mentioned above. But all Seventh-Day Adventists should seriously consider the following: a recognized prophetess in their church was a teacher of aberrant doctrine, and their church has its roots in the failed prophecies of William Miller.
