“Mountains of Faith” (Part 4 of eight) profiles two young Ethiopians who are embarking on very different life paths: one wants to be a Christian priest, the other an entrepreneur. But spirituality is important to the budding businessman, too. He's 15-year-old Artisagne, who left his farming village for Addis Ababa, the capital, where he's shining shoes (for now) and saving up for presents when he returns home for the religious festival Maskal. Meanwhile, Kibkab, 16, is facing “a major spiritual test,” says narrator Joe Morton, that will determine his future in the Ethiopian Orthodox Church.
