All humanists worship humanity, but they do not agree on its definition.
Today, the most important humanist sect is liberal humanism, which believes that “humanity” is a quality of individual humans, and that the liberty of individuals is therefore sacrosanct.
Another important sect is socialist humanism. Socialists believe that “humanity” is collective rather than individualistic.
The only humanist sect that has actually broken loose from traditional monotheism is evolutionary humanism, whose most famous representatives are the Nazis.
