This paper deals with the development of the theme of unclean spirits in theology of the Czechoslovak Hussite Church. The generation of the founders of the church influenced by radical Modernism, rejected the existence of unclean spirits, and the question of the origin of evil in the world was solved with a reference to privatio boni.
The following theological generation pointed out that the theme of evil powers is directly connected with the message of redemption in Jesus Christ, according to the model, "Nullus diabolus, nullus redemptor." Despite the fact that the theology of the CSHC re-opened the question of unclean spirits, it has never officially treated the subsequent question concerning possession and exorcism, although this phenomenon can also be marginally found in the Church.
