Archbishop Josef Glemp of Warsaw, the leader of the Roman Catholic Church in Poland, will arrive in Washington Oct. 14 to begin a two-week visit to northeastern and midwestern cities.

The tour, at the invitation of the president of the U.S. Catholic hierarchy and the bishops of the dioceses Glemp will visit, is being described as strictly pastoral, and no official meetings with U.S. government officials have been scheduled.

Glemp is to arrive the evening of Oct. 14 at Dulles and will go from there to an 8:30 mass at Our Lady Queen of Poland in Silver Spring. The public is invited but seating is limited.

The next day he will hold a news conference, visit the headquarters of the U.S. Catholic Conference, lunch with Apostolic Delegate Pio Laghi and concelebrate a mass at 7 p.m. at the National Shrine of the Immaculate Conception. The mass is open to the public; President Reagan and members of Congress have been invited.

After the mass, there will be a $20-a-plate dinner open to the public at Trinity College, with the proceeds to go for Polish relief aid. Reservations can be made by calling Margaret Ross at 681-6679.

Glemp leaves the next morning, Oct. 16, for Philadelphia. The rest of his schedule is as follows: Oct. 17, Detroit; 18, Toronto; 19, Cleveland; 20, Buffalo; 21, Springfield, Mass.; 22, Worcester, Mass.; 23, Boston; 24, Chicago; 25-27, Detroit and Orchard Lake, Mich.
