A man prays during a mass held by Pope Benedict at the Stade de l'Amitie (Friendship Stadium) in Benin's economic capital Cotonou November 20, 2011. The pope celebrated the big open-air Mass on Sunday, capping his three-day pastoral trip to Africa where he appealed to leaders to serve their people honestly and to developed nations to shun a condescending, know-it-all attitude towards the continent.
