The third volume of Theo-Drama is considered the most central book of Fr. von Balthasar's entire theological project. Structrually it is the middle volume of the middle part of his theological trilogy: Glory of the Lord, Theo-Drama, and Theo-Logic. More significantly, it contains von Balthasar's synthetic treatment of the central mysteries of the Catholic Faith: Christ, Mary, the Church, man and the Trinity.The various elements of von Balthasar's theological reflection converge here, and here as nowhere else one can find the systematic elaboration of his Christology, Mariology, ecclesiology, anthropology and trinitarian doctrine. It is both a one-volume compendium of this theology and a key to his trilogy and other writings.
