at the link, which points out that many scholars and at least one archaeologist are skeptical of a connection between Revelation and Roman curses.
But Revelation does have some really vile descriptions of what will happen to non believers during an apocalyptic End Times battle between good and evil. It almost didn't get included in the Bible. It's validity as a book representing the teachings of Jesus has been challenged many times over the centuries. The Eastern church rejected it.
Martin Luther thought that its presence in the Bible was questionable because it addresses the beliefs of a limited number of people during a brief period in the early church, but does not convey the teachings of Jesus about love, compassion, and forgiveness. He left it in his translation of the Bible into German, but made his views about it known.
I was raised in the Lutheran church. We were taught that Revelation uses symbolism that people understood when it was written, but which people today would not understand. I was also taught to reject the various meanings and predictions that modern fundamentalists and evangelicals give to it because they do not understand the political and social context in which it was written.
So, Revelation was not discussed in Sunday School or in sermons other than to tell us to more or less ignore it.
Dr. Bart Ehrman is mentioned in the link. He is a well recognized, well regarded secular historian of the Bible who grew up in a fundamentalist church but is now an atheist. He is not antagonistic to religion in general and says that he respects Jesus' reachings on how to live, but does not accept the theological doctrines of Christianity.
In another post in this thread I linked a video in which Ehrman describes the content of Revelation, explains what it's symbolism meant in the time when it was written, and gives a little background on the author's purpose in writing it.
