Rebel Earth - Dale E. McClenning

The world changed when aliens, taking the form of God from the Bible, arrived on Earth and took twenty-four thousand people away with them. After they left, the believers left behind flocked to the countryside and took up simple, agrarian lives, while the high-tech cities walled themselves off and braced themselves for the aliens' inevitable return.

A hundred and sixty years have passed. While prejudice between Puritans and Citizens persists in the United States, peace has reigned for three generations. However, when doctors in Chicago discover exactly what the aliens were looking for on their last visit, President Worthia Amster knows that their time to prepare is over.

The Citizens have decided that they will no longer be subservient to the aliens, their crop to be farmed as they please. But is Earth truly ready to rebel against the EO-AY, especially when half the population supports them?
