"Gebets-Schwestern" - original title?

[BigFish]

I am wondering what the original Italian title is for Salieri movie Gebets-Schwestern (released in german by the distributor Goldlight) ?

Goldlight has stripped the movie of the original title frame as well as the cast list. It is only labeled 'Gebets-Schwestern' which does not help much.

The film consists of eight scenes where nuns are having sex and a scene where a priest has sex with a girl. However, it is not the 'Il Mistero del convento' movie, which is a totally different film.

Anyone who has more information about Gebets-Schwestern?

This film could be a compilation of nuns scenes, looking at the three images on orgazmik I can say you that:
1st. Sacro e profano
2nd. Il confessionale
3rd. Il ritorno di don Tonino
