Protests against the president of the Democratic Republic of Congo have resulted in the arrest of 10 Catholic priests — a sign of the government’s willingness to defy church authorities at the forefront of the movement to oust its authoritarian leader. The protests against President Joseph Kabila on Sunday (Jan. 21), called by the church’s Lay Coordination Committee, began after Mass and resulted in clashes in which six people were killed and more than 100 wounded, according to the United Nations. “The church deplores the excessive use of force on demonstrators who were only armed with Bibles, rosaries and branches,” said Abbé Donatien Nshole, the secretary general of the National Episcopal Conference of Congo, in a statement to RNS.
