I am a former Seventh-day Adventist who still believes that the early SDA church uncovered many truths lost during the dark ages. I have to laugh though when I hear SDAs preaching to Catholics about how Sunday is the mark of the Catholic church (and I beilieve this is easily shown) and yet they themselves have accepted the central doctrine of the Catholic Church, the Trinity doctrine which was created by Catholics. Listen to the Catholics brag on not only how "Protestants" keep Sunday with no scriptural authority, but she (Catholics) brags how "Protestants" have acceted the Trinity doctrine as well with no such doctrine laid out in the Bible:
James White, as editor of the Review & Herald, reprinted a portion of the Catholic Doctrinal Catechism in 1854 to display the papal claims over Scriptural authority and acceptance by Protestants of the papal traditions. Please take special notice of the highlighted sections where Sunday is compared to the Trinity as not being in the bible!
"Q. Have you any other proofs that they [Protestants] are not guided by the Scriptures? "A. Yes; so many that we cannot admit more than a mere specimen into this small work. They reject much that is clearly contained in Scripture, and profess more that is nowhere discoverable in that Divine Book.
"Q. Give some examples of both? "A. They should, if the Scripture were their only rule, wash the feet of one another, according to the command of Christ, in the 13th chap. of St. John; - they should keep, not the Sunday, but the Saturday, according to the commandment, 'Remember thou keep holy the Sabbath-day;' for this commandment has not, in Scripture, been changed or abrogated.
"Q. Have you any other way of proving that the Church has power to institute festivals of precept? "A. Had she not such power, she could not have done that in which all modern religionists agree with her; - she could not have substituted the observance of Sunday, the first day of the week, for the observance of Saturday, the seventh day, a change for which there is no Scriptural authority.
"Q. Do you observe other necessary truths as taught by the Church, not clearly laid down in Scripture? "A. The doctrine of the Trinity, a doctrine the knowledge of which is certainly necessary to salvation, is not explicitly and evidently laid down in Scripture, in the Protestant sense of private interpretation”. (Review and Herald, August 22, 1854)
Right about now SDAs will start saying that "our Trinity doctrine is different than the Catholic"--this is a big lie, if it were "different" you would still be ostrasized as a cult (like you were when you were non Trinitarians) as the Jehovah Witnesses are to this day! And growing up SDA I can tell you SDAs have a "Christian" version for everything in the world, Adventist Champagne (many of them drink now), Adventist meat, Adventist intermural sports (a time when they would not compete among other schools but could beat the hell out of each other) and the list goes on and on, oh yes and Adventists swears...
This same church claims that the Catholics follow the Popes dictates...they (SDAs) should stop pointing the finger at the Catholics for SDAs follow (when convenient) the dictates of Ellen White, who is reffered to in their doctrinal book over 110 times! I say when convenient because if they really were following her they would not be teaching evolution now in their schools, they would not send their preachers to other seminaries, they would not teach "higher education" and again the list could go on and on...
