Studying texts by Lydia Maria Child, Sarah Grimke, and Margaret Fuller, this article seeks to recover the early phases of a dialogue that moved marriage away from an institution grounded in ideas of unification and toward a concept of marriage grounded in liberal ideas about equality. It seeks to situate the “marriage question” within both the rhetoric of American antebellum reform and of liberal religious thought. Rather than concluding that these early texts facilitated a movement toward a contractarian ideal of marriage this article concludes that Child, Grimke, and Fuller, sought to discredit unification as an organizing idea for marriage and replace it with a definition that placed a spiritual commitment to equality between the partners as the animating core of the idea of marriage.
