Pope Leo XIV is making a long and ambitious odyssey across four African countries -- Algeria, Angola, Cameroon and Equatorial Guinea. The visit will put Leo’s linguistic, cultural and endurance chops to the test, even for a relatively young and fit pope who loves to travel and crisscrossed the globe as superior of his Augustinian religious order. The 70-year-old Leo will cover about 11,000 miles on 18 flights over 11 days starting Monday. He'll deliver speeches and homilies in French, Spanish, Portuguese and English in a part of the world that is crucial for the continued growth of the Catholic Church, but poses unique challenges as well.
