The question what to believe is perhaps the most momentous that any one can put to himself. Our beliefs are not to be classed among the luxuries, but among the necessaries of existence. They become particularly important in times of trouble. They are like the life-boats carried by ocean ships. As long as the sea is smooth and there is every appearance of a prosperous voyage, the passengers seldom take note of the boats or inquire into their sea-worthiness. But when the storm breaks and danger approaches, then the capacity of the boats and their soundness become matters of the first importance. Ethical religion affirms the continuity of progress toward moral perfection. It affirms that the spiritual development of the human race cannot be prematurely cut off, either gradually or suddenly; that every stone of offence against which we stumble is a stepping-stone to some greater good; that, at the end of days, if we choose to put it so, all the rays of progress will be summed and centred in a transcendent focus. Religion is concerned with the foreign relations of mankind, that is to say, with our relations to the whole of outside nature. The mission of religion is to convince us that the foreign power is friendly. The non-ethical religions have represented the eternal outside power as manifesting its friendliness by warding off unhappiness and ministering to the temporal well-being of man. Ethical religion restricts itself to affirming that the eternal power assures the fulfilment of our moral aims. The non-ethical religions have based the belief that there is a higher power on the testimony of supernatural revelations. Ethical religion bases its belief solely upon the testimony of conscience, which declares that progress ought to be achieved, hence inferring that it will be. That the moral obligation remains in force is the capital fact to which we must hold fast, no matter what may be our theories of life and the Universe. The recognition of this obligation, the hearty avowal of the supremacy of the moral end above all other ends of life, is the first article of a practical ethical creed. There may be, and there ought to be, progress in the moral sphere. The moral truths which we have inherited from the past need to be expanded and re-stated. In times of misfortune we require for our support something of which the truth is beyond all question, in which we can put an implicit trust, “though the heavens should fall.” A merely borrowed belief is, at such time, like a rotten plank across a raging torrent. The moment we step upon it, it gives way beneath our feet. Good deeds remain good, no matter whether we know how the world was made or not. Vile deeds are vile, no matter whether we know or do not know what, after death, will be the fate of the doer. We know, at least, what his fate is now, namely, to be wedded to the vileness.
