Summary

Baptism opens a window to the heart of Martin Luther’s 16th-century theology. It offers a perspective for how Luther understands the impact of grace and its channels, as well as the nature of justification in an individual’s life. In his teaching about baptism, Luther demonstrates the vital working of the Word and lays a foundation for a Word-centered and faith-oriented spirituality. With baptism, Luther articulates his vision for the purpose of the Church and the rationale for sacraments. Baptism reveals different sides of the theologian: one who argues with a zeal on the “necessity” of baptism and its meaningful God-mandated practice in Christian communities and another who imagines God’s saving grace too expansive to be limited to any ritual. The apparent tensions in Luther’s articulation can be understood from his overlapping agendas and different audiences: in his baptismal talk, Luther is both processing his own Angst about salvation and negotiating his developing position in relation to the medieval sacramental theology and other emerging reform solutions. While feistily refuting his opponents, he is also speaking from his personal religious experience of being as if reborn with the encounter of the Word of grace and passionately extrapolating his most foundational conviction: God’s unconditional promise of grace as the ground of being for human life, given to humanity in the Word. The matter of baptism leads to the roots of different Christian “confessional” traditions. The format of the ritual has generated less anxiety than differing theological opinions on (1) the role of faith in the validity of baptism, and (2) the effects of baptism in one’s life. Whether infant or adult baptism is favored depends on whether baptism is primarily understood as a sign of faith, a cause of forgiveness and transformation, or an initiation into the Christian community—or all of the above. Baptism is at the center of Luther’s theological nervous system; it connects with every other vital thread in the theological map. Baptism is a mystery and a matter of faith; it calls for a philosophical imagination and mystical willingness to grasp the questions of reality beyond what meets the eye. “I study it daily,” Luther admits in his “Large Catechism.” “In baptism, therefore, every Christian has enough to study and practice all his or her life. Christians always have enough to do to believe firmly what baptism promises and brings.”
