In literature, the term "Unitarian" is employed with a rich variety of nuances, reflecting both religious affiliation and broader cultural or ideological stances. It often designates formal religious or institutional membership—such as when a preacher delivers a sermon in a Unitarian church [1] or when addresses are made to Unitarian bodies like the Ministers' Institute [2][3]. At other times, the label serves to enhance character or denote an alignment with progressive thought, as when a preacher’s sermons are praised [4] or a minister holds both spiritual and political office [5]. Moreover, it can be used metaphorically to signify the overcoming of restrictive traditional beliefs, exemplified by Emerson's imagery of breaking "Unitarian fetters" [6]. Even discussions that involve differentiating doctrinal identities, as in the case of confusing a woman's religious affiliation with Unitarian orthodoxy [7] or linking Unitarianism with eclectic groups [8], illustrate the term's complex, multifaceted role in literary discourse.
