By nationalizing, do they mean forcing everyone to be Christian or only allowing one type of church? Because I’m pretty sure a certain group of people fled their country over that issue.
I seriously doubt they’ll try to force everyone to be Christian. Aside from all the atheists who wouldn’t like it, there is a fairly substantial Muslim population in the western part of China that would immediately kill some people if that happened. Although the Muslim population is a small percentage of China’s total, the raw number of Muslims in China is very comparable to the number of Muslims you’ll find in Syria, and I’ll leave it at that.
If I’m understanding the situation correctly, there may be a silver lining. It’s awfully far from ideal, but it may be something we can see as a small step in the right direction, something that can be built on. From what I am understanding, China used to be officially atheist, and all formal organized religion was illegal. More recently however, visitors to China from outside the country enjoy much more freedom to participate in formally sanctioned religious gatherings and observances that- in the experience of Protestants I know at least- basically amount to all the freedom that they want to have in practicing their religion. Again, this particular bit of progress is exclusive to visitors from outside China. China’s even become more permissive of evangelism in a certain sense, although regular Chinese citizens from the mainland aren’t allowed to go to the same religious services as foreigners and the foreigners are really not supposed to invite them. But Christians can talk about Christianity and take that conversation as far as it can go, just as long as there’s no invite to the gathering in question.
With that being said…I think we’re seeing just a bit of progress with religion among regular Chinese people too. Atheism used to be the rule of law, and now it seems like China is permitting exactly one kind of state-run church (edit- actually, now exactly three state-run churches) that they’ll only feel comfortable with if they can control certain things. Again, it’s pretty far from ideal, but it may be a step in the right direction. The thing needs to exist in the first place, and then perhaps China will eventually be more comfortable with having less oversight and less specific control over time.
The other thing to look for is the shifting demographics of China. It’s an aging country that will need to bring in a lot of immigrants before too long, and it’s very likely that quite a few of those immigrants will be of Chinese descent. How will China handle a dual-citizenship situation when a Chinese person is from Hong Kong, or Taiwan, or a third generation descendant of Chinese emigrants to California? How will their religious liberties be handled? That would normally be hard to say, but in this developing situation where China needs these people very much, I’d say they get to do whatever they want.
China already has different sets of rules for different types of people living within its borders. All of those rules are slowly evolving in a positive direction, and I’m particularly optimistic about how things are looking for the far-more-permissive sets of rules for those born outside of China, because China’s in the process of becoming an immigrant destination far more than an immigrant sending country.
Now on the other hand- and this is referenced in the source- the Uighurs, the Muslims in western China, continue to be repressed more aggressively, AFAIK. From what limited information I have, it seems like we’re seeing Muslim repression at close to the maximum level while there’s a bit of a draw-down on the Christian repression. This isn’t anything like forcing everyone to become Christian, but I don’t think you have to be a Muslim in order to see it as the beginning of a significant comparative advantage for Christianity.
