It was also responsible for precipitating the investigation into the Secretariat of State’s controversial investment in a London building — a purchase now at the heart of a major Vatican finance trial.

The IOR, commonly called the Vatican bank, first agreed to give a loan to the Secretariat of State for the mortgage on the London property. But the IOR suddenly changed course and made a report to the auditor general, who investigated.

The pronouncement was part of a May 24 rescript on the tasks of the Office of the Auditor General signed by Cardinal Pietro Parolin, secretary of state. The rescript was issued following an April 24 meeting between Parolin and Pope Francis.

The pope said in light of the provisions of the Church’s apostolic constitution Praedicate Evangelium, “the ordinary administration, in case of a vacant Apostolic See, would not be interrupted and that the function of control would continue to be exercised by the Office of the Auditor General under the supervision of the Cardinal Camerlengo.”

The camerlengo is responsible for overseeing the preparations for a papal conclave and managing the administration of the Holy See during the sede vacante.

Pope Francis has also decided to change part of an article in the statutes of the Office of Auditor General.
