Christina Rossetti (1830-94) is regarded as one of the greatest Christian poets to write in English. While Rossetti has firmly secured her place in the canon, her religious poetry was for a long time either overlooked or considered evidence of a melancholic disposition burdened by faith. Recent scholarship has redressed reductive readings of Christian theology as repressive by rethinking it as a form of compassionate politics. This shift has enabled new readings ofRossetti's work, not simply as a body of significant nineteenth-century devotional literature, but also as a marker of religion's relevance to modern concerns through its reflections on science and materialism, as well as spirituality and mysticism. Emma Mason offers a compelling study of Christina Rossetti, arguing that her poetry, diaries, letters, and devotional commentaries are engaged with both contemporary theological debate and an emergent ecological agenda. In chapters on the Catholic Revival, Pre-Raphaelite Brotherhood, contemporary debates on plant and animal being, and the relationship between grace and apocalypse, Mason reads Rossetti's theology as an argument for spiritual materialism and ecological transformation. Sheultimately suggests that Rossetti's life and work captures the experience of faith as one of loving intimacy with the minutiae of creation, a divine body in which all things, material and immaterial, human and nonhuman, divine and embodied, are interconnected.
