Before the time of Augustine in the fifth century, premillennialism dominated the early church. Most of the early church fathers voiced a strong belief in a future one thousand year reign of Jesus.
Although on the surface it might seem to be an insignificant change, amillennialism profoundly changed the church in the centuries after Augustine. It altered the church’s view of Scripture, as well as of prophecy, and the negative impact of Augustine’s doctrine of future things continues to this day.
