While he is more commonly known for his Trinitiarian works and theology, this study assesses mid-fourth-century bishop Hilary of Poitiers'' view of the human condition. Isabella Image shows that the Commentary on Psalm 118 is more closely related to Origen''s than previously thought. Image explains how his articulations of sin, body and soul, the Fall and the will all parallel or echo Origen''s views in this work, but not necessarily in his Matthew Commentary. Hilary has a doctrine of original sin (''sins of our origin'', peccata originis), which differs from the individual personal sins and for which we are individually accountable. He also articulates a fallen will which is in thrall to disobedience and needs God''s help, something God always gives as long as we show the initiative. Hilary''s idea of the fallen will may have developed in tangent with Origen''s thought, which uses Stoic ideas on the process of human action in order to articulate the constraints on purely rational responses. Hilary in turn influences Augustine, who writes against the Pelagian bishop Julian of Eclanum citing Hilary as an example of an earlier writer with original sin. Since Hilary is known to have used Origen''s work, and Augustine is known to have used Hilary''s, Hilary appears to be one of the stepping-stones between these two great giants of the early church as the doctrines of original sin and the fallen will developed.The Human Condition in Hilary of Poitiers not only identifies Hilary''s anthropological thought, but also places it in the current of theological development of the fourth century. It considers reception of Origen in the mid-fourth century, before the criticisms of Epiphanius and the debates in the Egyptian monastic communities. This work also contributes to understanding of the tradition from which Augustine received his doctrine of original sin.
