Pope Francis urged Catholic priests on Sunday to guard against spiritual groups that stoke political divisions, speaking during a one-day visit to Corsica, the first by a pontiff to the French Mediterranean island.

Pope Francis on Sunday called for a "healthy secularism" while visiting the French island of Corsica. Christian and secular culture should not be pitted against each other, said Francis, who is the first pope to ever visit the Mediterranean island.

On the first papal visit ever to the French island of Corsica, Pope Francis on Sunday called for a dynamic form of laicism, promoting the kind of popular piety that distinguishes the Mediterranean island from secular France as a bridge between religious and civic society.
