From Bishop Muller's Wiki entry
Clerical celibacyIn response to controversial reactions to comments by Archbishop Robert Zollitsch of Freiburg that, while clerical celibacy is a gift but not theologically necessary, but that it would be a "revolution" if the celibacy tradition within the Latin Rite Catholic Church were abandoned, Müller said: "The Second Vatican Council made clear in Article 16 of the "Decree on the Ministry and Life of Priests" what the decisive requirements are".
EucharistIn 2002, bishop Müller published the book "Die Messe - Quelle des christlichen Lebens" (St. Ulrich Verlag, Augsburg). In the book, he says : "In reality, the body and blood of Christ do not mean the material components of the human person of Jesus during his lifetime or in his transfigured corporality. Here, body and blood mean the presence of Christ in the signs of the medium of bread and wine."
Liberation theologyMüller was also a pupil of Gustavo Gutiérrez, the “father” of Latin-American liberation theology, with whom he has a long and close friendship. Commenting on Guitierrez, Müller stated: "The theology of Gustavo Gutiérrez, independently of how you look at it, is orthodox because it is orthopractic and it teaches us the correct way of acting in a Christian fashion since it comes from true faith." It is important to note that Gutiérrez’s thoughts were never censored by the Holy See although it was asked that he modify a few of his writings.
MariologyIn his 900-page work "Katholische Dogmatik. Für Studium und Praxis der Theologie" (Freiburg. 5th Edition, 2003), Müller says that the doctrine of the Perpetual Virginity of the Blessed Virgin Mary is "not so much concerned with specific physiological proprieties in the natural process of birth [...], but with the healing and saving influence of the grace of the Savior on human nature."
Status of Protestant communitiesIn a speech he gave in October 2011, Müller said that "the Catholic Magisterium is far from denying an ecclesial character or an ecclesial existence to ‘the separated Churches and ecclesial Communities of the West".
