Really?
"Let history speak. In Eusebius's Ecclesiastical History, Book III, Chapter 28, is preserved a fragment from the writings of Caius, who lived about the close of the second century, which gives us the following account of Cerinthus's heresy:
"....And being an enemy to the scriptures of God, wishing to deceive men, he says that there is to be space of a thousand years for marriage festivities." "One of the doctrines he taught was, that Christ would have an earthly kingdom."
"....And being an enemy to the scriptures of God, wishing to deceive men, he says that there is to be space of a thousand years for marriage festivities." "One of the doctrines he taught was, that Christ would have an earthly kingdom."
The idea that the Millennium is for physical pleasure is a Gnostic idea. That is the heresy, not the idea of a Millennium itself. The idea of a Millennium is found in Scripture in Revelation 20. The idea of it being for physical pleasure is explicitly against Scripture. That, not the Millennium itself, is the heresy.
