Ordenes announced his decision in a letter to Pope Benedict XVI, through the apostolic nuncio Ivo Scapolo, representative of the Holy See in the southern country, reported the newspaper La Tercera.
Sources from the clergy confirmed that Scapolo advised the bishop to submit his resignation at a meeting they held in early October.
After the Vatican accepts the request, one of the bishops of the Great North could assume his duties temporarily, as apostolic administrator.
In recent days, one of the victims of religious, Rodrigo Pino, told Radio Cooperativa that his relationship with Ordenes began in 1997, when he was 15, and it was now that he dared to make a report after he knew that the bishop had also abused another child.
