Even before he was ordained a priest, the Rev. Ronald Lange was sent to Ghana by his Catholic religious order in 1968. In a profile by a community newspaper years later, Lange spoke of his commitment to learning about Ghana while teaching at schools there and leading a parish with more than a dozen worship sites. “The people are just so happy to see you,” Lange, a member of the Society of the Divine Word’s Chicago province, based near Northbrook, was quoted as saying. “You don’t even have to be a good priest.” And he wasn’t, as his order now acknowledges.
