On 16 May 1937, the Gestapo ordered Mayer to stop speaking in public which he obeyed, but he continued to preach in church. Mayer spoke out against anti-Catholic baiting campaigns and fought against Nazi church policy. Since he believed that a Catholic could not be a National Socialist, conflict inevitably arose between him and the Nazis. He preached that Man must obey God more than men.
