JPII Supplanted Calvary With Auschwitz and Knelt Before It

"Auschwitz, along with so many other concentration camps, remains the horribly eloquent symbol of the effects of totalitarianism. It is our duty to make a pilgrimage to these places, in mind and heart, on this 50th anniversary. As I said at the Mass celebrated in 1979 at Brzezinka near Auschwitz: 'I kneel at this Golgotha of the modern world.'"
(Message of John Paul II on 50th Anniversary of the end of WWII in Europe, May 8, 1995)
