In 1933, Hitler signed the Reichskonkordat (Reich Concordat), a treaty with the Vatican that required the regime to honour the independence of Catholic institutions and prohibited clergy from involvement in politics. However, the regime continued to target the Christian churches to weaken their influence. Throughout 1935 and 1936, hundreds of clergy and nuns were arrested, often on trumped up charges of currency smuggling or sexual offences.

LOL “trumped up charges”.

Goebbels widely publicised the trials in his propaganda campaigns, showing the cases in the worst possible light. Restrictions were placed on public meetings, and Catholic publications faced censorship. Catholic schools were required to reduce religious instruction and crucifixes were removed from state buildings. Hitler often vacillated on whether or not the Kirchenkampf (church struggle) should be a priority, but his frequent inflammatory comments on the issue were enough to convince Goebbels to intensify his work on the issue. In February 1937 he stated he wanted to eliminate the Protestant church. https://en.wikipedia.org/wiki/Joseph_Goebbels#Church_struggle
