in reply, cardinal müller wrote in february 2018 that, when understood in the sense of a "fundamental change in theoretical forms of thought and social behavior," there can be no paradigm shifts in the catholic faith. müller wrote that "a paradigm shift, by which the church takes on the criteria of modern society to be assimilated by it, constitutes not a development, but a corruption." müller also wrote that "familiaris consortio" established the discipline "that the divorced living in a new union must resolve to live in continence or else refrain from approaching the sacraments," and that any claim that "familiaris consortio" anticipated a change in this discipline "would have to violate the basic rules of logic."
