People wave to Pope Francis as he makes his way to the Metropolitan Cathedral in Santiago de Cuba, Cuba, Tuesday, Sept. 22, 2015. Pope Francis on Tuesday called on Cubans to rediscover their Catholic heritage and live a "revolution of tenderness," powerful words in a country whose 1959 revolution installed an atheist, communist government that sought to replace the church as the guiding force in people's lives.
