Okay kiddo, so there was this group of people called the Nazis who believed that some people were better than others just because of things like their race or where they came from. They thought that some races, like the German one, were superior to others.
Now, the Nazis didn't like the Catholic Church very much either. They thought that the Church was too powerful and that it was keeping Germany from becoming as great as it could be. They also didn't like how some priests and bishops spoke out against the Nazi ideas.
So, the Nazis tried to control the Catholic Church. They made some laws that said the Church couldn't do certain things and they sometimes even arrested priests and bishops who disagreed with them. But even with all of this, many Catholics still didn't support the Nazis.
In the end, the Nazis' views on Catholicism were pretty negative. They thought the Church was getting in their way and didn't like how some people were still loyal to the Church instead of to the Nazi ideas. But even though the Nazis tried to control the Catholic Church, it didn't work out the way they wanted it to.
