I literally was coming to the non-Catholic Religions Forum to ask the question if SDA are just predisposed to being anti-Catholic, but now I guess that would be redundant? I don’t know if I’ve ever seen an Adventist on this site but id like to ask them. I know a few who are otherwise good people. One is adamantly anti-Catholic and is always trying to prove to me the evils of the Church, he was presently surprised how well I knew the Bible (I majored in Biblical studies in seminary) despite being Catholic. Another Adventist I’ve known since middle school seems to be indifferent towards Catholics, she even came to Mass with me once and had wanted me to attend a service at her church too but I never did, I was a little scared that someone there may come at me negatively for being Catholic. However, one day I curiously asked her why they observed Saturday Sabbath, thinking she would say it was because they were keeping with the Jewish tradition, but she replied that the Catholic Church changed it to Sunday and it was suppose to be Saturday, she didn’t say it to be offensive but simply because that was what she was always taught. So then I asked what day does she celebrate Easter? Because since Jesus rose on a Sunday, it superseded the Saturday Sabbath.
I was at an Adventist hospital once and while in the waiting room I read one of their publications, they preach anti-Catholic and anti-protestant (nonSDA) rhetoric as well. What I also don’t understand is many just call themselves “Christians” unaware that their church was founded on the teachings of a modern prophet, Ellen White.
