Church leaders were realistic about the concordat 's supposed protections . Cardinal Faulhaber is reported to have said " With the concordat we are hanged , without the concordat we are hanged , drawn and quartered . " After the signing of the concordat the papal nuncio exhorted the German bishops to support Hitler 's régime . The bishops told their flocks to try to get along with the Nazi régime . According to Michael Phayer , the concordat prevented Pius XI from speaking out against the Nazi Nuremberg Laws in 1935 , and though he did intend to speak out after the nationwide pogrom of 1938 , Cardinal Pacelli dissuaded him from doing so
