The end of the XXI century is characterized to be a time of crossroads, which is placed under the demiurge sign of the crisis generated by the modern knowledge polarization type of sau/sau. With the new postmodern period of the beginning of the XXI century, we begin to make references to a new form of life and culture, which is different from the modern era. The sign under which the post-modernity is manifesting itself is being given by the size of the new multifaceted techno-science, of the ultra-liberal economic ideology manifested in theory, including, in cultural relativism, the belief that nothing is totally bad nor absolutely good (neither / neither) . Against this post-modern vision, the Orthodoxy will respond leading from the anthropological-social-political implications of the fundamental mystery of the Christian faith, which is (re)found in the model of the Trinity and in the Theological hrisologic-ecclesiological Trinity model, in terms of the diversity in identity and the multiplicity in unity. By this popular Trinity model, the Orthodoxy will offer the eternal dynamic model and the open identity in which the unit is confusing, and the difference is not being divided, and through the popular Christological-ecclesiologic, universality is achieved in particular (nationalcultural), features, opening, theanthropic, towards universal, through Jesus Christ. These two models, through the Christian vision, which is restorative and curative, will lead ultimately towards a personalist society.
