"I am here to bear witness and I am proud of being Catholic". The square of the Cologne Cathedral is packed with young people wearing the red shirt of the voluntary workers. Joanna Piatkowska, from Poland, talks. The twenty year old from Warsaw tells SIR "Today, faith is confined to the private sphere in the name of tolerance. That is wrong because we should express what we are. The lay faithful of other religions freely express their belief. We should also do that without being ashamed. Christianity represents our roots she added. This is the basis of our present and of our future". This opinion was also shared by Tomasz Stracalh, Bartomiey Kutalh, Magdalena Foyck and Magdalena Gunia. They are all in their twenties. They are some of the 800 young people working as volunteers who come from the land of John Paul II: "We are here they said also to remember him and support Benedict XVI at the beginning of his pontificate".
