Some demands of the German bishops, but also the reaction of Cardinal Schönborn on the occasion of the ad limina visit of the Austrian bishops, the task of the foundation as well as the meaning of the supernatural life of the Church.
The Foundation: natural law and divine law
All matters, marriage and the family and in a wider sense including ethics, belong in the area of natural law and therefore also apply to non-Catholics and even the unbaptized.
Thus, the indissolubility of marriage, for example, anchored in natural law and not even a specific feature of the Catholic Church, such as Pope Pius IX. noted at the time (1864).
How much more are Catholics who are also bound by revelation and the Divine Law.
Also, the questions on the orderly transmission of human life at the latest by the encyclical Humanae Vitae of Pope Paul VI. (1968) definitively magisterial, so it would not have questionnaires or still require a special debate.
The German Bishops' Demands: Theoretical Undermining the Natural Law
Therefore, when the German bishops demand, citing the result of the "questionnaires" in their dioceses, to question the attitude of the Church with regard to premarital cohabitation, birth control, remarried divorcees, and even homosexuals, not to be "unnatural", and so they replace natural law by the "explicit outreach" for mortal sins.
Cardinal Schönborn's Demand: Practical Disobedience and Creeping Protestantization
Although Cardinal Schönborn notes that for the doctrine of the Church, nothing will change. For him it's all about how to deal with "situations of failure."
But in practice the result is the same as the German bishops: They want - to put it in the words of Bishop Krenn in his opinion on Maria-Troster Declaration - an erroneous, deviation of conscience from the teachings of the Church to grant a certain universality.
Thus, this episcopate moves in the footsteps of the reformer Martin Luther, who put his ego and his personal opinion above doctrine and tradition.
The result was not only a schism with devastating consequences, but the reduction of the Church to a humane society without supernatural character.
