Which term denotes hypocrisy in religious devotion?

Sanctimony refers to the act of pretending to be morally superior to other people, particularly in a religious context. It often conveys a sense of self-righteousness or hypocrisy in expressing one's devotion or moral beliefs while failing to practice what one preaches. This term captures the essence of insincerity in religious devotion, where an individual may outwardly display piety or righteousness but does not embody those principles in their actions or behavior.

The other terms do not convey the same meaning. Rumination involves deep or considered thought, particularly regarding one's past experiences or actions. Ruffian denotes a violent person or a scoundrel and does not relate to religious devotion. Retinue refers to a group of advisors or assistants accompanying an important person, which is not relevant to the context of hypocrisy in devotion. Thus, sanctimony is the right term to express religious hypocrisy.
