Keep the faith – that was Pope Benedict’s message in an address to Poles on the second day of his visit to his predecessor’s homeland. He urged the crowd not to let consumerism and secularism undermine their religious belief.More than 300,000 people attended the open air mass in Warsaw – the rain may have played a part in keeping the numbers much less than the one million expected to turn up. It took place in the same square where, 27 years ago, Pope John Paul inspired his compatriots to defy communism in an impassioned speech. It is regarded as a key moment in the collapse of communist regimes across eastern Europe. Perhaps the most poignant moment of the trip will come on Sunday when the German pope visits the Nazi death camp at Auschwitz.
