Pope’s ex-student to welcome his mentor to Madagascar quarry 'cathedral'

September 02, 2019 - Madagascar, Africa - Three times a year, Father Pedro Opeka celebrates Mass in a vast grey quarry in the hills above Madagascar's capital. This week, he will welcome his old teacher, Pope Francis, to see the chiseled granite altar. Opeka studied theology under the future pope in their native Argentina before dedicating his life to building communities for the families of Madagascar, one of the world's poorest nations.
