The idea that each age lasts 1000 years is based on
II Peter 3:8: "But of this one thing be not ignorant, my beloved, that one day with the Lord is as a thousand years, and a thousand years as one day." The interpretation was taken to mean that mankind would live through six 1,000 year periods (or "days"), with the seventh being eternity in
heaven or according to the
Nicene Creed, a
World to Come. Medieval Christian scholars believed it was possible to determine the overall time of human history, starting with Adam, by counting forward how long each generation had lived up to the time of
Jesus, based on the ages recorded in the Bible. While the exact age of the earth was a matter of biblical interpretive debate, it was generally agreed man was somewhere in the last and final thousand years, the Sixth Age, and the final
Seventh Age could happen at any time. The world was seen as an old place, with more time in its past than its future. While Augustine was the first to write of the Six Ages, early Christians prior to Augustine found no end of evidence in the Jewish traditions of the
Old Testament, and initially set the date for the
End of the World at the year 500.
Hippolytus said that the measurements of the
Ark of the Covenant added up to five and one-half
cubits, meaning five and a half thousand years. Since Jesus had been born in the "sixth hour", or halfway through a day (or, five hundred years into an Age), and since five kingdoms (five thousand years) had already fallen according to Revelation, plus the half day of Jesus (the body of Jesus replacing the Ark of the Jews), it meant that five-thousand five-hundred years had already passed when Jesus was born and another 500 years would mark the end of the world. An alternative scheme had set the date to the year 202, but when this date passed without event, people expected the end in the year 500. By the 3rd century, Christians no longer widely believed the "End of the Ages" would occur in their lifetime, as was common among the
earliest Christians. ==See also==
