“The reform that the official church now needs is called separation of powers,” he told the weekly newspaper “Die Zeit”. He asked why the official church was still clinging to a centralistic and absolutistic form of organization that “no longer works”.
With regard to his church, the Catholic criticized that the “premodern constitution” generated “a lot of resistance and reluctance” in this country. This church constitution is "archaic authoritarian" and "alien to freedom". To pass them off as Jesus' will means "to fool the people". The reform that the official church now needs is the separation of powers. The clerics should use their power to restrict this in a legally binding manner. “I don't see any other way out of the impasse of absolutism.” Self-binding could help to separate the powers of lawmaking, law implementation and jurisprudence that have hitherto been united in the episcopate. This would "change the shape of the church at one stroke". Concretely, zu Eltz suggested that the faithful be involved in the appointment of pastors and bishops, "so that Catholics are no longer ashamed in the democracy of their church". That would also give the church a new kind of bishop, “who prefers to trust and receive, prefers to listen to the criticism of free spirits, prefers to have loyal employees with a backbone? to remain as a prince of the church whose power prevents him from being human ”. The city dean also criticized the alienation of the church leadership from the church people. In view of the massive resignations from the church, he literally demanded of the clergy: "But if you don't want to be a normal person, you have to prevent you from becoming a bishop." Eltz originally belonged to the conservative wing of his church. The Frankfurt Cathedral, of which he is the landlord, belongs to the Limburg diocese. During the building scandal surrounding the Limburg bishop Franz-Peter Tebartz-van Elst, the city dean had openly criticized his employer ?? and so contributed to its removal.
