RE: The strongest group in China is Reformed.
Do you have a source for this factoid? ( a link maybe?)
If you search the Guardian, for example, you will find an article. The Reformed are by far the most influential Christians in China because they are well educated and often in “interesting” positions. I’ve seen this first hand during my travels in China (including the one that I just returned from).
Is Bavinck’s work a big seller in the US? It is in China.
