Forty years ago the communists got what they wanted, and lived to rue the day.

When Archbishop Karol Wojtyła of Kraków was elected Pope John Paul II in October 1978, the question arose of how Moscow and Warsaw would deal with a potential papal visit to his homeland. The communists wanted no part of a pope behind the Iron Curtain. St Paul VI had accepted the invitation of the Polish bishops to visit for the millennium of Poland’s baptism in 1966, but the Polish regime and its Soviet overlord refused to permit the Holy Father to come.
