Context: He must be a man of little faith, who would fear to subject his own religion to the same critical tests to which the historian subjects all other religions. We need not surely crave a tender or merciful treatment for that faith which we hold to be the only true one. We should rather challenge it for the severest tests and trials, as the sailor would for the good ship to which he trusts his own life, and the lives of those who are dear to him. In the Science of Religion, we can decline no comparisons, nor claim any immunities for Christianity, as little as the missionary can, when wrestling with the subtle Brahmin, or the fanatical Mussulman, or the plain speaking Zulu.
