Approximately 2/3 of all non-Catholic Christians believe in a literal paradise earth.... they just don't call it that. They call it the Millennial Reign of Christ.
Amillennialists deny a literal millennial reign:
Eastern Orthodox
Oriental Ortodox
Roman Catholic Church
Lutheran
Reformed
Anglican
Methodist
Episcopalian
Augustine started amillennialism in the late 300's. That view today, is generally a carry-over from roots in the Roman Catholic church.
The majority of everyone else believes in a literal thousand-year reign, as did the early church leaders.
The first premillennialists [belief in a literal millennial reign] were those who received God's revelation and wrote it down in the Bible. Eusebius tells us that one of the earliest church fathers that had heard the Apostle John and others who had known the Lord and His Apostles was Papias (AD 60-130), the bishop of Hierapolis in Phrygia, Asia Minor. Papias taught "that there will be a millennium after the resurrection of the dead, when the kingdom of Christ will beset up in material form on this earth."
(1) Irenaeus (AD 130-202) tells us that Papias "related that they had heard from him how the Lord used to teach in regard to these times" (the Millennium) in book 4 of Papias' writings, which are no longer extant, except a few fragments. Papias is recorded as saying: "there will be a millennium after the resurrection from the dead, when the personal reign of Christ will be established on this earth."
(2) Polycarp (A.D. 70-155), bishop of Smyrna, is also said to have been a premillennialist.
(3) The Epistle of Barnabas (written between AD 120-150) presents the common belief that "in six thousand years, all things will be finished ....then shall He truly rest on the seventh day." The writer speaks of the second coming of Christ with the clear implication that He will setup the thousand year kingdom on earth, followed by the eighth day or the eternal state.
(4) Justin Martyr (AD 100-165) in his Dialogue With Trypho c. AD 140, a Jewish man, made the following premillennial statement: "But I and others, who are right-minded Christians on all points, are assured that there will be a resurrection of the dead, and a thousand years in Jerusalem, which will then he built, adorned, and enlarged, as the prophets Ezekiel and Isaiah and others declare."
(5) Justin Martyr considered premillennialism an aspect of orthodoxy in his day, "And further, there was a certain man with us, whose name was John, one of the apostles of Christ, who prophesied, by a revelation that was made to him, that those who believed in our Christ would dwell a thousand years in Jerusalem; and that thereafter the general, and, in short, the eternal resurrection and judgment of all men would likewise take place."
I had a kind lady explain this to me one day in field service. I stopped going in field service when I understood that vast numbers of Christians already believed in a "paradise earth".
