Political praxis is a constituent and essential part of Christian living, as much at the personal as at the ecclesial level. This dynamic is characterized by having as an absolute reference point the historic experience of Jesus in the exercise of popular sovereignty (which seeks the construction of common good), the separation of Church and State, the prevalence of ethics and right, the realization of the preferential option for the poor and the constitution of an authority and minimal consensus at the local, national and international levels. The purpose of this paper is to assess the ethical-theological foundations starting from the biblical facts, the Church tradition and the engagement of Christian contemporary community. The
present publication is the first part of a text which will be completed in the next issue of this magazine.
