"Father Roberto Francisco Daniel can no longer celebrate the divine rite because he has been excommunicated," a statement from the Bauru diocese in Sao Paulo state said.

The 48-year-old priest, who renounced his church duties over the weekend, was accused of "heresy" and "schism" by the church hierarchy in the world's biggest Catholic country, which will welcome Pope Francis in late July during a major youth festival in Rio de Janeiro.
