Film scholar Thomas Atkins attests that, while "The Devils" contains overt themes regarding religion and political influence, the film is in fact more concerned with "sex and sexual aberrations." He interprets the film as being centrally thematically interested in sexual repression and its cumulative effects on the human psyche. Commenting on the Sister Jeanne character, Atkins writes: "There are any number of examples of tormented visualization involving the Mother Superior...  What more stunning visual metaphor for the psychological suffocation of the Mother Superior than to stuff her deformed body into a tiny lookout space from which she watches her fantasy lover? The mere confinement of mass in congested space creates an understanding of the annihilating pleasures of her sexual drive." Atkins likens Sister Jeanne's erotic fantasy sequences to "eroticism from a deranged consciousness."
