The Conclusion provides a summary of the arguments of each chapter and shows how they cohere in Hilary of Poitiers’s trinitarian anthropology. In his autobiographical section of De Trinitate Hilary claims to have found “a hope greater than expected” (Trin. 1.11) in his contemplation of the infinite God, in which humanity, aided by its educative embodied existence (1.14), is destined for life and progress, not death and regress. Hilary’s theology reconstructed within his framework of trinitarian anthropology illuminates his own thought and provides avenues to reassess the nature of fourth-century theology and its controversies in a way that implicates the nature of humanity in that theological discourse. For Hilary, imperfect, mutable, finite human existence is defined by God’s perfect, immutable, and infinite life, so as to place the human condition in a state of perpetual progress from potentiality to perfection.
