This book presents an original Marian approach towards war and peace, dedicated to the suffering of children, women and men in Mariupol and elsewhere in Ukraine and in the world. Offering new theological perspectives on the contemporary impact of war, the contributions take inspiration from the figure and symbol of Mary - as protector of children and guardian of peace, intermediary of the incarnation, as well as model for ecumenical, interreligious, and intercultural engagements. The chapters explore the role of Mary as a symbol for feminist and activist reflections, for the communication of suffering as the mater dolorosa, for power when appropriated for political ends, and for healing and reconciliation in peace-building efforts. The book provides readers with valuable theological reflections on conflict, global theological ethics, ecofeminist and peace-building thinking in theology, and contemporary political theology.
