Muller was tapped to head the Vatican's doctrine office, the most important dicastery in the Roman Curia, by Benedict XVI before his resignation in 2012. The charge included the positions of president of the Pontifical Commission “Ecclesia Dei,” the Pontifical Biblical Commission and the International Theological Commission.

Pope Francis renewed Muller's appointment to the CDF and to each of the commissions after his election, allowing the prelate to serve the entirety of his 5-year term in each, which ends July 2.

The Vatican announced July 1 that taking Muller's place will be Jesuit Archbishop Luis Ladaria, who was appointed secretary to the CDF by Benedict XVI in 2008, and is known to be simple, orthodox in his theology, highly intellectual and is described by those who know him as not being a “yes man.”

 

In his interview with “Allgemeine Zeitung,” Muller simply stated that his 5 year mandate as prefect of the CDF “had now run its course,” and the decision to replace him had nothing to do with conflict that's been painted between he and the Pope.

Nor was it the result of differing opinions on Francis' 2016 post-synodal apostolic exhortation “Amoris Laetitia.” While the two didn't agree on all aspects of the text, the cardinal insisted there was no fight about it.

Despite their disagreements on some points, Muller is known to have been a conservative voice within the Curia, and, contrary to other German prelates, backed more traditional interpretations of Chapter 8 of the document, which touched on the reception of communion for divorced and remarried couples.

However, the cardinal did voice his disappointment in Francis' decision to dismiss three members of his staff a few weeks ago, noting that the officials “were competent people.”

 

Regarding his new role, Muller said that after ceasing his position as head of the CDF July 3, he will stay at the Vatican.

“I will work academically, continue to serve in my role as cardinal, do pastoral work. There is enough for me to do in Rome,” he said, adding that “in any case, I would normally be a pensioner by now.”
