There have been - and still are - some wonderful Chinese Catholic authors. One of the best known of these writers is Wu Li, who was not only one of the orthodox masters of early Qing-dynasty painting but also a poet and Jesuit priest.
The most comprehensive guide to Wu Li can be found here (with further details here) but a more accessible introduction to his work can be found here. According to Chaves, his poetic sequence "'Singing of the Source and Course of Holy Church' succeeds in achieving Wu Li's goal of creating a Chinese Christian poetry, true to Chinese traditions of allusion, parallelism, and other familiar poetic techniques and true also to orthodox Christian theology, piety, and liturgical solemnity." Rather than do him the injustice of a brief quotation, I'll try to return to some of the poems themselves (in Chinese and in English translation) in a later post.
Another great Chinese Catholic writer who is only now beginning to be given her due is Su Xuelin. This article from Harvard's Divinity School is encouraging, though also a little baffling. Although Su Xuelin converted to Catholicism in the 1920s while studying in France, Zhange Ni argues that the religion her alter-ego embraces in Ji Xin, the novel Su Xuelin wrote about her conversion, "is not Catholicism or Western religion per se, but a not-so-readily-available, still-struggling-into-being Chinese discourse of religion, which cannot be reduced to a slavish adoption of modern Western concepts of religion."
