In early March, Zollner was appointed a consultant to the Diocese of Rome’s new office for the protection of minors and vulnerable adults.

He is also the director of the Institute of Anthropology: Interdisciplinary Studies on Human Dignity and Care (IADC), hosted by the Pontifical Gregorian University.

The IADC, formerly called the Center for Child Protection, is an academic institute offering higher-education degrees in abuse safeguarding and anthropology.

In his statement, Zollner said he has “grown increasingly concerned” with the Vatican’s safeguarding commission and its lack of “responsibility, compliance, accountability, and transparency.”

“I am convinced that these are principles that any Church institution, let alone the Pontifical Commission for the Protection of Minors, is bound to uphold,” he said.

Hours before Zollner released his critique, a March 29 statement from Cardinal Sean O’Malley, president of the Vatican’s safeguarding commission, characterized the Jesuit priest’s departure as an effort to reduce his already significant administrative responsibilities, including  “his recent appointment as consultant for Safeguarding to the Diocese of Rome.”
