WASHINGTON – On April 3, 2018, the eve of the 50th memorial of the assassination of the Rev. Dr. Martin Luther King, Jr., following the solemn service of the Bridegroom of Holy Tuesday, His Eminence Archbishop Demetrios hosted more than 400 ecumenical leaders and guests at the Greek Orthodox Cathedral of St. Sophia in an effort to progress efforts to end racism. The event, co-organized by the National Council of Churches of Christ in the USA (NCC), preluded a march from the MLK memorial to a rally on the National Mall taking place the next morning, April 4.
