Communists hate Bible doctrines and Christian churches because they tell the truth and enable people to see how gullible people can be. And reveal the deception that is communism.
Communism and its little sister socialism are a national con trick. Tell the people that everybody is "equal" and some will believe anything. Liberalism goes one step further and tells the masses that authority and morals can be removed from society and total freedom (relativism) can exist.
This political virus is peddled today by Bernie the Democrat and his associates.
But if anyone causes one of these little ones who believe in Me to stumble, it would be better for him to have a large millstone hung around his neck and to be drowned in the depths of the sea. (Mat 18:6)
See that you do not look down on any of these little ones. For I tell you that their angels in heaven always see the face of my Father in heaven. What do you think? If a man has a hundred sheep and one of them goes astray, will he not leave the ninety-nine on the hills and go out to search for the one that is lost? And if he finds it, truly I tell you, he rejoices more over that one sheep than over the ninety-nine that did not go astray. In the same way, your Father in heaven is not willing that any of these little ones should perish. (Mat 18:10-14)
President Xi Pooh (yes, ironically, Pooh is his first name) and any other leader who use and take advantage of children (especially children of believers) do not escape the observation by the Father and His angels. I've read that China banned a Winnie the Pooh film in 2018 because they felt it would cause him to mocked. Of course, banning a children's film is peanuts compared to banning married couples from having a certain number of children and using kids to spy on parents of believers.
