Luther’s theology is strongly Christocentric, but Christology is rarely the central focus of his writings. In some of his most considered summaries of his own faith, he presents Chalcedonian Christology alongside the church’s teaching on the Trinity as the uncontroversial foundation of the Catholic faith, which he shared with his opponents. At the same time, it is evident that Luther’s most celebrated theological innovations, including his teaching on justification by faith, his theology of the cross, his soteriology, and in particular his doctrine of the Eucharist, had considerable Christological implications that sometimes seem at variance with received orthodoxy.
Luther’s Christology must therefore be largely reconstructed from these various strands in his thought. The result is a distinctive albeit not systematic Christology that is focused on the paradoxical unity of divine and human in Christ. In this, Luther often appears close to the teaching of the Alexandrian fathers, but with a much fuller emphasis on the concrete humanity of the savior. His historical debt to late scholasticism is most evident in his few, albeit consequential, attempts to enter into the field of technical Christological doctrine, especially his affirmation in his controversy with Zwingli of the ubiquity of Christ’s human nature after the ascension.
