She has never compromised on Christ's teaching and morality. Consequently she has frequently had evil men and evil forces arrayed against her. We know from the World War what enemy propaganda can do. It was debated recently which branch of the military won the World War, the army or the navy. After long discussion the conclusion was reached that neither army nor navy had won the victory, but that propaganda had won it.
War propaganda means trying to influence opinion against the enemy.
Directly after the World War was over, people on both sides were astonished to learn that nearly all the reports they had accepted and believed concerning the enemy were so many fabrications or exaggerations. The Catholic Church is at war with the world. The World War had an end. The war between the Church and the world will never end. Consequently, propaganda in one form or another will always be active against the Catholic Church.
