The observation led Pedroso, a Brazilian journalist, to examine what might be leading people in Indigenous communities to essentially swap Christian faiths. It became the focus of a project he reported in the fall of 2019 for the Pulitzer Center on Crisis Reporting's Rainforest Journalism Fund, titled "River Missionaries: The Catholic Counteroffensive in the Amazon."
