Resumen:
The doctrine of the general priesthood of all believers challenges the Christian Church to live and publicly witness to the Gospel of Jesus Christ beyond ecclesiastical spaces. The theme of the general priesthood received considerable attention in the theological reflection of the reformer Martin Luther, being approached at different times and in many of his writings, under different perspectives and emphasis. The implications that can be drawn from the doctrine of the general priesthood in Luther's theology is that Christian people are called to interact and influence the place where they live based on faith and commitment to the Gospel, which is shown in a concrete way in the social and professional activities and relationships that the Christian person develops. This is the same emphasis that the concept of the missional Church seeks to promote in its understanding of mission in the world and for the world. Thus, the central question that the research seeks to answer is to what extent the general priesthood of all believers and its relationship with the concept of the missional Church can effectively contribute to the performance and witness of the Christian person in contemporary society, especially in the Brazilian reality of the 21st century.
