ON BOARD THE PAPAL PLANE - POPE Benedict XVI warned on Saturday of a very strong clash between faith and modernity in Spain and he called for dialogue, not confrontation.

The pontiff said an anti-clerical movement erupted in Spain in the 1930s in the run-up to the Spanish Civil War.

'The clash between faith and modernity is happening again and it is very strong today,' he told reporters accompanying him on the plane before landing in Spain's holiest city Santiago Compostela for a two-day visit.

The 83-year-old leader of more than one billion Roman Catholics called for Spain and the whole of Europe to have a 'meeting between faith and secularism and not a confontation.'
