This volume is a translation into Arabic of the papers and discussions published as part of the Pro-Oriente ecumenical consultation between members of Roman Catholic, Chaldean Catholic, Syro-Malankar, Syrian Orthodox, Maronite, and Assyrian Orthodox Churches, originally published in Vienna in 1994. Many of the papers in this volume are commentaries by members of the various churches represented at the consultation on the joint declaration issued by Pope John Paul II and Patriarch Denha IV. A number of other papers seeks to address the question of whether the Council of Ephesus unites or divides.
