At a dress rehearsal on Wednesday evening a performer had walked around the church altar wearing a string bikini with large dildo strapped to her, APA reported.
Pachl, who once temporarily led the Berlin Symphony Orchestra in the German capital, said he was forced to cut the sexually explicit material otherwise the monastery would have cancelled the two performances on Thursday and Friday.
Pachl said there had been no complaints from monastery officials during early rehearsals of the opera, but only after the first public preview.
Monastery officials had "not been invited" to the rehearsals, the spokesman commented.
