By Catholic Herald by Staff - In an interview with Infovaticana, German prelate, Cardinal Gerhard Ludwig Müller, the former Prefect of the Congregation for the Doctrine of the Faith, has warned that Pope Francis has no authority to change the teaching of the Church. This is not the first time Müller has taken a stand against Pope Francis, having recently warned about the Vatican’s silence on China’s abuses and Cardinal Zen’s “unfair” trial in Hong Kong.
