Once you are saved, God will make you into His true worshipper (Jn 4:23). Consequently, you will intensely desire to worship God both as an individual and together with other believers. God commands you to assemble with His church (Heb 10:25)—we therefore should consider what He has said about it, so that we may attend the one He has ordained, not one people have invented. Consider the following truths:
1.) The true church recognizes that the 66 books of the Bible were all “given by inspiration of God” and are able to make the believer “perfect, throughly furnished unto all good works” (2 Tim 3:16-17) without any other authority, such as allegedly inspired writings of other people. Since every single word and even letter of the Bible is inspired (1 Cor 2:13; Deut 18:18; Jer 36:2; Ps 12:6-7; Mt 5:18), we are to live “by every word that proceedeth out of the mouth of God” (Mat 4:4), and not “add unto the word . . . neither . . . diminish ought from it” (Deut 4:2; 12:32).
Furthermore, the apostles and prophets were the foundation of the church (Eph 2:20). Once the foundation was laid in the prophetic and apostolic writings of the New Testament, “the perfect” canon of Scripture, “prophecies . . . [were] done away” (1 Cor 13:8-13). With the final revelation of God in the New Testament, no more inspired books or true apostles and prophets will come before Jesus Christ returns. On the other hand, “many false prophets shall rise, and shall deceive many” (Mt 24:11; 7:15). Consequently, the last chapter of the last book of the Bible warns “every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: and if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book” (Rev 22:18-19).
For that matter, even when there were true apostles and prophets before God gave the complete New Testament, there were no women prophets or preachers who taught men, because God said: “Let the woman learn in silence with all subjection. But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence” (1 Tim 2:11-12). “Let your women keep silence in the churches: for it is not permitted unto them to speak; but they are commanded to be under obedience, as also saith the law. And if they will learn any thing, let them ask their husbands at home: for it is a shame for women to speak in the church. What? came the word of God out from you? or came it unto you only? If any man think himself to be a prophet, or spiritual, let him acknowledge that the things that I write unto you are the commandments of the Lord” (1 Cor 14:34-37). Women prophets (Ac 21:9) prophesied only to women, not to mixed groups that included men. Biblical writers of Scripture such as the Apostles also did many miracles to validate their message, from healing those lame from birth to raising the dead (2 Cor 12:12; Mt 10:8; Ac 3:2-11; 9:41; 20:12).
Furthermore, all true prophets were 100% accurate in their predictions. Since God cannot lie (Tit 1:2), even one false prophecy meant a prophet was not speaking God’s Word but was from the devil, and was worthy of death: “[T]he prophet, which shall presume to speak a word in my name, which I have not commanded him to speak . . . even that prophet shall die. And if thou say in thine heart, How shall we know the word which the LORD hath not spoken? When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that is the thing which the LORD hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him” (Deut 18:20-22).
Seventh-Day Adventism adds the allegedly inspired and infallible writings of the supposed prophetess Ellen G. White—who prophesied and exerted authority over men to the extent that she founded the SDA religion—to the truly inspired Bible, and thus falls under the curse of Rev 22:18-19 and other passages: “The Holy Ghost is the Author of the Scriptures and of the Spirit of Prophecy [Mrs. White’s writings].” “Ellen G. White[’s] . . . writings . . . are a continuing and authoritative source of truth.” “We believe the revelation and inspiration of both the Bible and Ellen White’s writings to be of equal quality. The superintendence of the Holy Spirit was just as careful and through in one case as in the other.” It is not possible that Ellen White’s writings were simply those of a sincere person with some truth in them and some error—they are either inspired like the Bible, or they are demonic. Mrs. White said: “My work . . . bears the stamp of God or the stamp of the enemy. There is no halfway work in this matter. The Testimonies are of the Spirit of God, or of the devil.”
Indeed, Mrs. White even taught at times that her words were more inspired than those in the Bible! God supposedly gave her specific words, but He did not inspire the specific words of Scripture: “The Spirit of God works upon my mind and gives me appropriate words with which to express the truth. . . . When writing these precious books, if I hesitated, the very word I wanted to express the idea was given me.” In contrast, “[i]t is not the words of the Bible that are inspired, but the men that were inspired. Inspiration acts not on the man’s words or his expressions but on the man himself[.]” While making high claims for her writings, Mrs. White nevertheless admitted that, concerning “miraculous works” like those of Christ and the Apostles, “we cannot now work in this way.” She claimed her writings had the same kind of inspiration as the apostolic NT books, but she was unable to perform apostolic miracles.
Indeed, while Mrs. White claimed to be a true prophet, her “inspired” writings are filled with errors and false prophecies. For example:
i.) Mrs. White predicted in June of 1850 that there were only a few months left before the seven last plagues, a decree that all Saturday-worshippers be put to death, and the end of the world: “In . . . June 27, 1850, my accompanying angel said . . . the seven last plagues were soon to be poured out . . . the inhabitants of the world would . . . suffer from incurable sores and withering plagues . . . and . . . be destroyed by them. Terror seized me[.] . . . Some of us have had time to get the truth . . . but now time is almost finished, and what we have been years learning, they [new SDAs] will have to learn in a few months. . . . Those who would not receive the mark of the beast and his image when the decree goes forth, must have decision.”
ii.) After this prophecy failed, she predicted that some people alive at a conference in 1856 would live until translated to heaven at the coming of Jesus: “I was shown the company present at the Conference. Said the angel: ‘Some food for worms, some subjects of the seven last plagues, some will be alive and remain upon the earth to be translated at the coming of Jesus.’” This prophecy failed also.
iii.) During the Civil War Mrs. White prophesied that England would declare war on the United States and humble America to the dust, leading to the downfall of the USA. As a result of “the war . . . to preserve the Union . . . [t]his nation will . . . be humbled into the dust. . . . When England does declare war . . . our nation . . . must fall.” The Civil War ended a very long time ago without England ever declaring war on the United States.
iv.) After the Civil War Mrs. White predicted: “Slavery will again be revived in the Southern States; for the spirit of slavery still lives. Therefore it will not do for those who labor among the colored people to preach the truth as boldly and openly as they would be free to do in other places.” Slavery has been illegal ever since the Civil War and has never been revived. The idea that one needs to be less bold and open in sharing Biblical truth with black people because they are going to be re-enslaved is self-evidently false. This prophecy failed also.
v.) Mrs. White’s prophecies also contain blatant factual errors. For example, she taught that after the flood of Noah’s day men and beasts interbred, resulting in certain black and Indian peoples: “Since the flood there has been amalgamation of man and beast, as may be seen in the almost endless varieties of species of animals, and in certain races of men.” The union of man and beast had created “such cases as the wild Bushmen of Africa, some tribes of the Hottentots, and perhaps the Digger Indians of our own country . . . it is impossible to tell just where the human ends and the animal begins.” However, science confirms that it is impossible for men and animals to produce offspring, and the idea that some races of people are part man and part beast is also utterly unbiblical (Ac 17:26).
vi.) Mrs. White also prophesied that Jupiter and Saturn are inhabited by people: “After counting aloud the moons of Jupiter, and soon after those of Saturn, she . . . said, ‘The inhabitants are a tall, majestic people, so unlike the inhabitants of earth. Sin has never entered here.’” There are no tall, majestic people that live on Jupiter or Saturn. The planets are uninhabited and uninhabitable. These are a few of the many false prophecies by Mrs. White.
vii.) The factual errors in her “prophetic” compositions are unsurprising since vast sections—sometimes up to 90%—of her works were plagiarized, including many portions that she specifically claimed she saw and received from God directly in visions. She plagiarized many books that were simply the products of fallible men who never dreamed of claiming that their works were inspired—her compositions, then, naturally have errors also. Seventh-Day Adventist historians and leaders have been forced to admit (though they have sought to cover up the facts for most of SDA history): “[T]here are serious errors in our authorized books . . . but we let . . . [t]he people and our average ministers . . . go on year after year asserting things we know to be untrue. . . . [W]e are betraying our trust and deceiving the ministers and the people. . . . [W]hat amounts to deception . . . has been practiced in making some of her [Ellen White’s] books.” “Ellen White . . . incorporated . . . the errors of the historians” she plagiarized “into her own text,” so that her works contain “errors in factual matters” as, at times, “virtually every paragraph is a quotation, close paraphrase, or summary” of uninspired writings by others, with the result that “her statements did not agree with the facts of history, science or biblical scholarship . . . Ellen White was not inerrant.”
 See “1 Corinthians 13:8-13 and the Cessation of Miraculous Gifts,” R. Bruce Compton, at http://faithsaves.net/truths-for-pentecostals-and-charismatics/ for detailed exegetical proof that miraculous gifts ceased with the completion of the New Testament.

Mrs. White also at times placed the Bible above her writings using “greater/lesser light” language; since she is not a true prophet, she is not consistent, but can put the Bible above, equal to, and beneath her own alleged “inspiration.” The SDA denomination makes her writings “the only infallible interpreter of Bible principles” (pg. 1, Mark of the Beast, G. A. Irwin, General Conference President) so that they are the “final court of appeal among God’s people” (pg. 6, Adventist Review, June 3, 1971). Were her writings genuinely the Word of God, they would be equal to the Bible, for there is no such thing as “levels” of inspiration.

Note also that Mrs. White’s vision contradicted the declaration of Jesus Christ that angels do not know the time of the second coming (Mt 24:36). Therefore, since Mrs. White’s accompanying angel told her Christ was going to return in the 1800s, he was not an angel of God, but a fallen angel. Mrs. White also, despite the strict warnings of Scripture (Dt 18:11), communicated with the dead in her “revelations”—or at least with fallen angels impersonating the dead—and claimed that what the dead told her was guidance from the Lord. She told a particular dead person, “[Y]ou are always to stay with me now and we will work together,” so that she could have the help of the dead from that time forward (Letter 17, 1881 Ellen White to W. C. White (9/12/1881), pgs. 38-40, Manuscript Releases vol. 10 & www.ellenwhiteexposed.com/egw61.htm).
