Chinese philosophy and spirituality are deep, rich topics. Christians who hope to share the gospel should learn all they can about the worldviews that shape the interior world of their East Asian friends, neighbors, and colleagues. Dr. Ping-cheung Lo has written a short series of posts on this very topic, giving an excellent overview of Daoism, Confucianism, and Buddhism and showing how they resonate with the Christian gospel. He also provides resources for further reading and understanding.
We should not erect an artificial barrier to sharing the gospel of Jesus by insisting on a Western language that non-Christians in Asia are not familiar with. Jesus is the answer, yes, but to what questions? East Asian people have a rich tradition of spiritual formation in the general sense of renovating the heart.
Christians need to acknowledge a fact. We might disagree on whether Confucianism is a religion or not. But Confucianism, together with Daoism and Buddhism, are spiritual traditions that have provided “chicken soup” for Chinese souls for more than two thousand years.
