In the context of the present ecumenical dialogue as well as the division of Christendom or its trivial acceptance, the author analyses various ways to overcome the lack of the in-depth dialogue among ecumenical communities and churches in the present spiritual situation of the postmodernity and challenges of globalization. The author does it through a new understanding of missionary in the reception of human oikoumene in a sense of associations of civilizations as cultural forms of Christendom. Consequently he is able to intelligibly grasp ecumenism as it is understood in the Gospel – in its direct sense of the New Testament term of hē oikouménē (“the whole inhabited world”).
