Inside the cavernous stone walls of the National Cathedral in Washington, DC, beneath large stained glass windows etched with the faces of Christian saints, Armenians from around the world once again stood united in a prayer for justice. On the grounds where former US President Woodrow Wilson—who was instrumental in providing aid to Armenian survivors a century ago—lies buried, more than two thousand people joined Armenian President Serzh Sargsyan, pontiffs of the Armenian Apostolic Church, US Vice President Joe Biden, diplomats, senators and members of Congress for an ecumenical service to remember the nearly 1.5 million martyrs of the Armenian Genocide.
