>> In February, the president of the German conference, Cardinal Reinhard Marx of Munich, announced that the bishops might allow remarried divorcees to receive Communion even if the upcoming synod decides otherwise, stating that they’re not a “subsidiary of Rome.” <<
Marx did NOT declare a formal schism, as this quote suggests. He said they are not “JUST” (merely? nothing other than a?) “a subsidiary of Rome.”
No, Marx is just threatening a formal schism. Whether Marx or Francis considers it a formal schism, or not, is a moot point.
