In my experience, having been raised to be “against” the Catholic Church but not actually as an anti-Catholic, the Seventh Day Adventists are my first (and so far only) experience in that genre. Here are the highlights of a sermon that gets recycled periodically in the local SDA congregation:
Catholics believe that Christ bows in humble submission to the egotistical priests who think they can “make” their maker with their own hands, by their own power, presumably without God’s permission.
The mark of the Beast is Sunday worship mandated by the Catholic Church; she is going to use the arm of the law to force everyone to take this “mark” and disobey God’s commands to keep a Saturday Sabbath.
The Catholic Church killed 50-75 million people during the Inquisition; she’s killed an average of 50,000 every year since the Church was founded.
She is the whore of Babylon, or the false prophet, and America is conspiring with her, unawares, to set up the Antichrist’s government. As proof that the Church is the false prophet of Revelation, she received a “mortal wound” when Pope Pius VI was arrested and died in prison at the end of the 18th century (as though no other Pope was a martyr), and was “resurrected” when Mussolini restored the Papacy’s sovereignty in 1929.
We must rely on the Word of God and reject the wine of the Papacy’s fornications.
Add miscellaneous misinterpretations of Catholic teaching and history, mixed with several truths interpreted as blasphemies.
All in one sermon.
I should add that the SDAs are among some of the gentlest, most diligent and pure people that I’ve met. I left the congregation a few years ago (never joined, just attended) and still maintain contact with a very wonderful older woman; she is the one who keeps me “updated” with sermon notes now and then.
