It's not clear at this point why Rome had to intervene or why they decided that Bianchi had to leave, but the Secretary of State, Cardinal Pietro Parolin, made an announcement at the beginning of May which was finalized swiftly. The Apostolic Visitation began on December 6th and ended on December 20th. The visitation was carried out by an ecumenical trio which included an Abbess.It was conducted by Father Guillermo León Arboleda Tamayo, Abbot President of the Subiaco Cassinese Benedictine Congregation, Father Amedeo Cencini, Consultor for the Congregation for Institutes of Consecrated Life, and Mother Anne-Emmanuelle Devéche, Abbess of Blauvac.
“Taking into account the ecclesial and ecumenical importance of the Community of Bose, both nationally and internationally, and the importance of continuing in its recognized role, overcoming serious hardship and misunderstandings that could weaken or even wipe it out, the Holy Father intended the Apostolic Visitation to offer help to the Community in the form of a period of listening led by some people of proven trust and wisdom.” At the end of the Apostolic Visitation, “the visitors presented their report to the Holy See, prepared on the basis of the contribution of the testimonies freely given by each member of the Community.”
If anything comes up, we'll be sure to let you know.
