This dissertation offers a constructive theological argument regarding the nature of the relationship between divine and human mercy. The study takes as its starting point the injunction in the Gospel of Luke: “Be merciful as your Father is merciful” (Luke 6:36), and argues that human mercy is at once a medium of divine mercy, and a mode of its reception. The work is divided into three parts. The first develops a constructive account of the mercy of God from the Hebrew Scriptures. The second contends that Jesus Christ is the definitive moment of divine mercy, and considers this claim and its implications through three stories, each of which contains a central trope (beloved, child, and friend, respectively) that comes to define the Christian Church in relationship to God through Christ. The final part argues, in conversation with the Christian mystical tradition, that human lives of mercy can be at once a sacraments and parables of divine mercy. “Being merciful,” it is concluded, is at once a promise of blessing and an injunction.
