There have been many predictions for the Rapture of the church. The author is not the first to suggest that it will occur on a 3,500-year old Jewish feast in Leviticus 23 called Trumpets. He offers no specific calendar day or hour for the Rapture. After nearly 30 years of study and careful contextual cross referencing of the Authorized (King James) Version of the Bible it is his conclusion that its actual day and hour is known exclusively by the Father. Its possible calendar day, however (Rosh Hashanah) is an annual event. The author has concluded that the Rapture is possible, even probable, on a future feast of Trumpets. His hope is that this treatise will serve as a warning for a church that is drifting ever further into apostasy.
