Religion and Morality

Religious themes permeate the story, from Brotherhood's atheist lectures and Marryatt's clerical role to the use of ecclesiastical words in the cipher, raising questions about faith, hypocrisy, and moral justification for murder.

Marryatt's sermon on Brotherhood's sudden death and the afterlife highlights themes of mortality, belief, and moral reflection.

Marryatt, a clergyman, justifies murder as 'doing God's work' and uses religious precedents, while Brotherhood's atheist lectures provoke the conflict.
