In Fredric Brown's short story "Answer," computers all across the galaxy are linked together to create a superpowerful, conscious computer.  When it is finished, it is asked the question, "is there a God?"  And the computer responds, as it seals shut the switch with a bolt of lightning, "there is now."  Similarly, in Isaac Asimov's short story, "The Last Question," the computer is asked whether entropy can be reversed.  The computer puzzles over the question as the universe cools down to absolute zero, until finally it says, "let there be light!" 

     The Creator (1935) by Clifford Simak features a world-creating alien and Parke Goodwin's Waiting for the Galactic Bus (1988) is about aliens who were responsible for breeding Homo Sapiens who have taken on the roles of God and Devil.

     Humans have had their delusions of grandeur as well.  In both Theodore Sturgeon's "Microcosmic God" (1941) and Edmond Hamilton's "Fessenden's Worlds (1937) feature scientists watching, presiding over, and controlling their tiny universal creations.  Other stories where humans create God or gods are The God Makers (1972) by Frank Herbert and Lord of Light (1967) by Roger Zelazny.

     2.  The second division of Holy Science Fiction includes stories that use religion as a tool of the government.

    In Margaret Atwood's The Handmaid's Tale, fundamentalist Protestantism is used to justify the subordination of women.  Keith Roberts Pavane (1968) is a collection of linked stories set in an alternate world in which Elizabeth I was assassinated and 20th-century England, technologically backward, remains oppressed by the Catholic Church.  In Walter Miller Jr.'s novel A Canticle for Leibowitz (1960), after the devastation of a nuclear war, a monastery collects and copies the books and artifacts of science and engineering.  Its library ultimately makes available the information necessary to recreate technical civilization that once more brings about nuclear destruction.  Others include John Campbell's "All," and Keith Robert's Kiteworld.

     3. The third division of Holy Science Fiction includes those stories that question and challenge the reality of God and the institution of religion.

     These stories are numerous (and are scattered throughout some of the other divisions - one good example being the aforementioned Waiting for the Galactic Bus, 1988).  In The Dawn of All (1911) by Robert Hugh Benson, the reader witnesses a utopian world where people have renounced materialism, humanism, socialism and Protestantism.  In Guy Thorne's When it Was Dark (1904) rationalism is employed to discredit the Christian faith.
