The measure concerns the male and female branches of the "Family of the Incarnate Word", the Dicastery for Religious Orders and Communities announced on Saturday.
The communities"Instituto del Verbo Encarnado" (Institute of the Incarnate Word) and "Servidoras del Senor y de la Virgen de Matara" (Servants of the Lord and the Virgin of Matara), which were founded in Argentina in the 1980s, have been in a prolonged crisis since allegations of abuse against the now deposed founder Carlos Miguel Buela came to light in 2010.
Vatican carefully monitored organisation from the outset
Following new investigations into both branches of the organisation, the community of priests will in future be led by the Argentinian bishop Jose Antonio Satue Huerto as papal delegate, according to the press release.
The female branch, on the other hand, will be under the direction of the nun Clara Echarte as Papal Delegate.
"Since their foundation, the Dicastery has always followed the affairs of the two institutes with particular attention and care," reads the communication signed by Simona Brambilla as Prefect and the religious Aitor Echave as Undersecretary.
The appointed delegates Huerto and Echarte should accompany the communities "especially in the areas of formation, religious discipline, apostolate and leadership".
The name of the "Family of the Incarnate Word" refers to a passage in the Gospel of St John.
There it says about the incarnation of Jesus Christ: "And the Word became flesh".
The community, which consists of a total of three branches, has branches in several countries, including two in Germany: Neumarkt in the Upper Palatinate and Pritzwalk near Berlin.
According to the members' self-portrayal, their aim is to contribute to the "evangelisation of culture" through their own activities.
The Vatican first took over the management of the community in 1995 and appointed papal delegates.
In 2001, the community's headquarters were moved from Argentina to Italy.
In 2010, Buela was dismissed for life and banned from contact following an internal church investigation into confirmed allegations of psychological abuse, financial irregularities and sexual assault.
However, Buela only partially complied with the conditions.
