The document discusses the biblical concept of the "abomination of desolation" mentioned in the books of Daniel and Matthew. It provides definitions of "abomination" and "desolation" and examines the four mentions of the phrase in the book of Daniel. The document suggests that the abomination of desolation referred to in Daniel was fulfilled by the Roman armies destroying Jerusalem in 70 AD. It argues that both pagan Rome and papal Rome acted as the abomination that desolated God's sanctuary through their idolatrous practices and persecution of Christians.
