About 800 people witnessed history June 18 as the Archdiocese of Omaha advanced to Rome the sainthood cause for Father Edward Flanagan, Boys Town founder. Archbishop George J. Lucas was the main celebrant of a morning Mass at St. Cecilia Cathedral in Omaha that marked the closing of the archdiocesan phase of the canonization effort with a special ceremony to encase and officially seal four boxes -- 4,600 pages -- of documents detailing the archdiocese's three-year investigation. The documents will be shipped to the Congregation for Saints' Causes at the Vatican. If the findings are accepted, recognizing Father Flanagan's heroic virtues, he will be declared "venerable." In general, two approved miracles attributed to the intercession of the candidate are needed for sainthood -- one for beatification and the second for canonization. The ceremony was a once-in-a-lifetime event, a first for the archdiocese, to have one of its members -- an archdiocesan priest -- advance toward possible beatification and canonization, said Omar Gutierrez, notary for the archdiocesan tribunal for the cause. Among those concelebrating the Mass were Bishop Kevin Doran of Elphin, Ireland, Father Flanagan's native diocese, and Father Patrick O'Toole, pastor of the parish in which Father Flanagan grew up in Ballymoe, Ireland.
