If we have once claimed the freedom of the spirit which St. Paul claimed: to prove all things and hold fast that which is good: we cannot turn back, we cannot say that no one shall prove our own religion, no one shall prove other religions and compare them with our own. We have to choose once for all between freedom and slavery of judgment, and though I do not wish to argue with those who prefer slavery, yet one may remind them that even they, in deliberately choosing slavery, follow their own private judgment quite as much as others do in choosing freedom. _Gifford Lectures, III._ Our own self-interest surely would seem to suggest as severe a trial of our own religion as of other religions, nay, even a more severe trial. Our religion has sometimes been compared to a good ship that is to carry us through the waves and tempests of this life to a safe haven. Would it not be wise, therefore, to have it tested, and submitted to the severest trials, before we entrust ourselves and those dear to us to such a vessel. And remember, all men, except those who take part in the foundation of a new religion, or have been converted from an old to a new faith, have to accept their religious belief on trust, long before they are able to judge for themselves. And while in all other matters an independent judgment in riper years is encouraged, every kind of influence is used to discourage a free examination of religious dogmas, once engrafted on our intellect in its tenderest stage. We condemn an examination of our own religion, even though it arises from an honest desire to see with our own eyes the truth which we mean to hold fast; and yet we do not hesitate to send missionaries into all the world, asking the faithful to re-examine their own time-honoured religions. We attack their most sacred convictions, we wound their tenderest feelings, we undermine the belief in which they have been brought up, and we break up the peace and happiness of their homes. Yet if some learned Jew, or subtle Brahman, or outspoken Zulu asks us to re-examine the date and authorship of the Old or New Testament, or challenges us to produce the evidence on which we also are quite ready to accept certain miracles, we are offended, forgetting that with regard to these questions we can claim no privilege, no immunity. _Gifford Lectures, III._
