Near Future Religious Movements In Three Future Histories

In James Blish's Cities In Flight, Belevers/Witnesses proclaim imminent immortality. Since they are based on Jehovah's Witnesses, they do not seek political power.

In Robert Heinlein's Future History, Nehemiah Scudder is a backwoods evangelist. A wealthy convert leaves him millions of dollars to found a TV station. He teams up with an ex-Senator and they hire a major advertising agency, then revive the KKK. Scudder becomes President and bans elections.

In Poul Anderson's Psychotechnic History, the White American Church grows in the American South during the lunatic years at the end of the twentieth century. Violently anti-intellectual and strangely orgiastic, it is encouraged by some politicians and grows in wealth. When the Second Conference of Rio indicates that UN world government will be followed by a federalist Solar Union, the enraged White Americans decide to emigrate to Ganymede where they found the city of X while their support on Earth dwindles undermined both by psychotechnic propaganda and by the expense of funding the remote colony.

The White Americans sound like Scudder's Angels of the Lord.
