More than 3,000 people packed the Basilica of the National Shrine of the Immaculate Conception Sept. 5 to mark the 13th anniversary of the death of Blessed Teresa of Calcutta, attend a memorial Mass and witness the unveiling of a commemorative stamp in honor of the nun. Archbishop Pietro Sambi, apostolic nuncio to the United States, was the principal celebrant of the memorial Mass in the upper church that preceded the U.S. Postal Service's unveiling of its commemorative stamp in honor of the centennial of Mother Teresa's birth. In his homily, Archbishop Sambi recalled the nun's "infectious and untiring work for her spiritual children," and said, "Mother Teresa loved God more than herself. Mother Teresa loved the church more than herself. Mother Teresa loved the poorest of the poor more than herself." He also praised her for "her passion in defense of life. She said the greatest disease is not being wanted and the greatest destroyer of peace is abortion."
