Leiber had been part of Lovecraft’s circle of correspondents and Leiber was always more a writer of weird fiction than science fiction.
In the distant future the world is governed by a theocracy. The priestly Hierarchy enforces the worship of the Great God. The power of that theocracy is now being challenged by occult forces, servants of the dread archfiend Sathanis. Rebellion is being plotted by the New Witchcraft.
But in fact it’s all an illusion. The reader knows this right from the start. There is no Great God. This is a synthetic religion invented by scientists to just a dictatorship of scientists. Miracles are performed regularly, but by means of advanced technology. There are angels, but they are really ultra-light aircraft. The Hierarchy has sophisticated mind control technologies and powerful drugs at its disposal. The population is kept in an uneducated superstitious state and the religion of the Great God has never been challenged.
Now occult forces, labelled the New Witchcraft, are at work spreading terror and confusion. But this is an illusion as well. There’s nothing supernatural about the New Witchcraft. They just have their own advanced technologies.
So what appears to be either a clash between opposing religions of dark and light, or a clash between science and magic, is in fact a power struggle between two fake religions invented by opposing factions of scientists and technocrats.
The trouble starts when a priest named Jarles suddenly harangues a crowd with a blasphemous anti-Hierarchy rant. He expects immediate arrest and punishment but it doesn’t happen.
The archpriest Goniface is gradually consolidating his control over the Hierarchy, driven by complex ambitions which will be revealed more fully at the end of the story.
There’s mind control in this book as well, a subject that would soon become an obsession for both science fiction and spy fiction writers. In Leiber’s novel a man’s personality can be moulded into a new form, but the old personality doesn’t quite disappear. Which can cause complications. Jarles is an enemy to the Hierarchy, he is remoulded into a loyal servant of the Hierarchy but there is now a major conflict set up in his mind. He has become an unpredictable factor.
The way technology is used to mimic the supernatural are quite clever. The witches have familiar spirits, but there’s nothing actually supernatural about them.
There’s certainly satire here but religion is not Leiber’s target. He’s more concerned with aiming his barbs at political ideologies and most of all he’s concerned with the way regimes (all regimes) construct an intricate web of deceptions to give themselves legitimacy.
The technologies deployed by both the Hierarchy and its opponents rely on the falsification of perceptions. Some of the more terrifying weapons are no more than illusions. The power struggle between the Hierarchy and will at times become violent but mostly it’s a lengthy complex exercise in the control of mass psychology. Fear is the most powerful weapon of all if it’s used subtly and effectively.
The major characters are all motivated by fears and by their own illusions and self-deceptions as well as ambition and, occasionally, the most deadly motivation of all - misguided idealism.
Gather, Darkness! is complex intelligent science fiction by one of the masters. Highly recommended.
I’ve also reviewed other Fritz Leiber books - You're All Alone and The Big Time.
