Throughout their shared history, Orthodox and Eastern Catholic Churches have lived through a very complex and sometimes tense relationship –-not only theologically, but also politically. In most cases such relationships remain to this day; indeed, in some cases the tension has increased. In July 2019, scholars of both traditions gathered in Stuttgart, Germany, for an unprecedented conference devoted to exploring and overcoming the division between these churches. This book, the second in a two-volume set of the essays presented at the conference, explores the ecumenical and practical implications of the relationship between Orthodox and Eastern Catholic Churches. Like the conference, the volume brings together representatives of these Churches, as well as theologians from different geographical contexts where tensions are the greatest. The published essays represent the great achievements of the conference: willingness to engage in dialogue, general openness to new ideas, and opportunities to address difficult questions and heal inherited wounds.
