The Most Rev. James Alousius Hickey will be formally installed as the Roman Catholic archbishop of Washington on Aug. 5, in ceremonies at St. Matthew's Cathedral.

Because space limitations at the 1,200-seat cathedral will restrict that ceremony to officially invite guests, the archdiocese is planning additional events at the Shrine of the Immaculate Conceptioin on Sunday, Aug. 10.

Following a mass celebrated by Hickey at 4 p.m. that day, he will meet Washington area residents at a festival on Catholic University grounds next to the Shrine.

The 59-year-old Hickey, currently bishop of Cleveland, was named by Pope John Paul II three weeks ago to head the Washington archdiocese. He is now touring Poland and Italy.

Hickey will formally present his letter of appointment to clergy and officials of the Washington archdiocese on Aug. 4 at a 7:30 p.m. vesper service for clergy only.

Cardinal William W. Baum is expected to be among the dignitaries attending the installation of his successor the next afternoon.

At Archbishop-elect Hickey's request, the traditional luncheon or banquet usually held follwing a new bishop's installation will be eliminated. In its place will be what church leaders are calling a "family festival" after the Aug 10 mass.
