When Christianity was a new and persecuted religion, many Christians believed the end times were imminent. Scholars debate whether Jesus was an apocalyptic preacher; however, his early followers, "the group of Jews who accepted him as messiah in the years immediately after his death, understood him in primarily apocalyptic terms". Prevalent in the early church and especially during periods of persecution, this Christian belief in an imminent end is called "millennialism". (It takes its name from the thousand-year ("millennial") reign of Christ that, according to the Book of Revelation, will precede the final world renovation; similar beliefs in a coming paradise are found in other religions, and these phenomena are often also called "millennialism")
