As you've most certainly read, Cardinal Müller, the Prefect of the Congregation for the Doctrine of the Faith was scheduled to speak in Madrid at the Catholic University associated with the Seminary. The Archbishop of Madrid, a recent appointee, as with Chicago, done with the direct intervention of Pope Francis barred the Cardinal from speaking at the University. An alternative location was found.The Archbishop, a man who may have misrepresented his own resume, had no authority to do this. No doubt, the Cardinal Prefect, ever a gentleman in the same mould as a former Prefect, made no fuss, at least, not a public one.
What was said by Cardinal Müller is of critical importance. Minions such as Madrid's Archbishop may say, he is "against the Pope" but Müller does not seem to have fallen for the ultramontanist papolatry so common with this Bergoglian papacy.
In his speech, the Cardinal Prefect was quite clear:
“It is not possible to live in God’s grace while living in a sinful situation,” he [Müller] said, and continued by saying that people living in sin “can not receive Holy Communion unless they have received absolution in the sacrament of penance.” Müller importantly added that the “Church has no power to change the Divine Law” and that “Not even a pope or council can change that.”
He also understands what it means to be a worshipper of God, not His Vicar.
