On Africa trip, Pope Leo will face debate over polygamy as Catholicism booms

VATICAN CITY — This week, Pope Leo XIV will walk in the footsteps of his icon, Saint Augustine of Hippo, a towering theologian whose birth in what is now Algeria makes him history’s most revered African Catholic. In strife-ridden Cameroon and authoritarian Equatorial Guinea, Leo will flex his powers as peacemaker and diplomat. In oil-rich Angola, he will confront a microcosm of the global tussle between Catholicism and evangelical faiths.
