"Earnest idolators make earnest Christians"?

I've been flicking through William John Townsend's biography of Robert Morrison. The latter was a Protestant missionary to China from 1807-1834, and Townsend's biography of him was written around 1890. Since CSR often stresses the role of doctrine in Christianity, I thought this passage (from p.266-7) was interesting.

"At the same time, women form a very important element of society. Their influence in the household, as in England, counts for a great deal. Having far less knowledge, they are far less under the influence of Confucian ideas, the most conservative ideas in the Empire. Their nature is much more religious than that of the men. The men trifle with their beliefs; the women are in earnest. They are capable of a practical faith, the men much less so. As a rule, the male part of the family are Confucian, the women Buddhists or Taoists. [...]

When the men pretend to worship them [the Chinese pantheon] they only play at it. But the zeal of the women has kept alive the faith in these grotesque and senseless deities, and supplied the impulse which from time to time has reconstructed their broken shrines and renovated their falling habitations. On this account they make much better Christians than the men. The men are satisfied with the cold abstractions and moral maxims of Confucianism, are interested in nothing higher than the earth or wider than the bounds of human life; the women must have something warmer and more emotional- they have deep cravings for the spiritual and the eternal. The men talk about their religion much, but practise [sic] it little; the women feel their religion, and thus practise it. The men can do without worship; the women cannot. Earnest idolators make earnest Christians. The affectations and aspirations which clung around and sanctified imaginary and superstitious beings, transferred to a living Christ and a god of eternal love, are the impulse to a new and holy life. Indifferent heathens make indifferent Christians. The habits of insincerity and practical scepticism which through a lifetime have been associated with a false faith are too often, on their conversion, retained in connection with the true.

Until woman, as the ruling power in the home and the influential factor in moulding the successive generations of China, is grasped and sanctified by the spirit of Christ, the work of the missionary will be largely in vain; but as in other great onward Christian movements, let the women be drawn into the Church, and the conquest of Empire will be chiefly accomplished."
