David Vincent Meconi presents the Incarnation as God’s purposeful gift for humanity’s transformation, not a merely unconditioned favor. Drawing on Athanasius, Saint Thomas Aquinas, and John Barclay’s analysis of ancient gift-giving in Paul and the Gift, he argues that grace is lavish and unearned while still directed toward a fitting response: gratitude, surrender, and participation in divine life. Barclay’s six features of grace—superabundance, singularity, priority, incongruity, efficacy, and noncircularity—help distinguish this account from modern notions of a “no-strings-attached” gift. The argument then turns to Saint Paul’s theology of the Mystical Body. Ancient political and social imagery, including the fable of Menenius Agrippa, illuminates Paul’s teaching that the Church’s many members depend on one another while retaining their distinct identities. Through baptism, the sacraments, and “putting on” Christ, believers are incorporated into his glorified body, united across divisions between Jew and Gentile, and called to see and serve Christ in their neighbors. Deification is therefore both a gift and a total vocation: Christ becomes human so that human beings may share in the divine nature, allowing grace to reshape personal identity and communal life.
