The life and theology of Karl Barth were marked by political and social engagement. This engagement didn t happen simply because Barth was politicized, but was a consequence of his theological understanding. For him, the Christian faith through the man of integral and non-dualistic mode, so there was no sphere of human life that doesn t belong to Christ. Being engaged and fight for the disadvantaged and exploited was a result of faith in Jesus, was to care what Jesus would mind. This involvement in the life of visceral and theologian Barth was fought by establishing in extreme moments when his own life was at risk. His theology was all permeated by a holistic thinking that creates holiness be a matter of fighting for human rights, democracy, the poor. His example and his work can be very relevant, especially in the socio-economic context of Latin America.
