The Tartars cannot unconsciously imbibe Christianity as the Finns have done.
Their religion is not a rude, simple paganism without theology in the scholastic sense of the term, but a monotheism as exclusive as Christianity itself.

Enter into conversation with an intelligent man who has no higher religious belief than a rude sort of paganism, and you may, if you know him well and make a judicious use of your knowledge, easily interest him in the touching story of Christ's life and teaching.
And in these unsophisticated natures there is but one step from interest and sympathy to conversion.
Try the same method with a Mussulman, and you will soon find that all your efforts are fruitless.

He has already a theology and a prophet of his own, and sees no reason why he should exchange them for those which you have to offer.

Perhaps he will show you more or less openly that he pities your ignorance and wonders that you have not been able to ADVANCE from Christianity to Mahometanism.

In his opinion--I am supposing that he is a man of education--Moses and Christ were great prophets in their day, and consequently he is accustomed to respect their memory; but he is profoundly convinced that however appropriate they were for their own times, they have been entirely superseded by Mahomet, precisely as we believe that Judaism was superseded by Christianity.
