Roots of Premillenial Theory

I was reading the book "Lives of the Popes" written in the 15th Century today. Very interestingly, the author had this to say:

What shall I say about the most foul teaching of Cerinthus? He said Christ's Kingdom would come after a thousand years and would be on Earth; hence in Greek he was called a "chiliast". Since he was intolerant of lusts and desires, he held out the prospect of sensual pleasures, an abundance of food and plenty of women, in the holy promises of the kingdom to come. Nepos, a Bishop in parts of Egypt, also believed this. He said that the saints would reign on Earth with Christ amid every delight and pleasure of the body. the followers of this filthy sect were called Nepotians.

Now, even if there is no direct link between these heretics and the premillenial theology that we hear today, it is very interesting that this worldly Kingdom and 1000 year reign of Christ was given no merit at all among the Early Church, and by the 15th Century, it seemed to be a very perverse idea indeed.
