We are bound to recognise the claims of others to equal treatment with ourselves, and any refusal or apparent refusal to do so must be justified by a universal rule applicable to all alike.  The perpetual attempt to justify exceptions in this way is sure to end in diminishing the number of those exceptions.  If we are compelled to think much of the position of woman in marriage, we are sure at last to come to Malachi’s declaration that God hateth putting away.  If we are compelled to think of the position of slaves, we cannot continue for ever to believe that there are some beings with consciences and free wills, who nevertheless, because of the accidents of their lives, have no rights at all; and we acknowledge the righteousness of Jeremiah’s denunciation of the breach of covenant when the nobles of Judah re-enslaved those whom they had solemnly emancipated.  If we think of the nature of responsibility and the justification of punishment, we find it impossible to believe that an innocent man shall be rightly punished for the wrong-doing of another, even if that other be his father or his mother; and we are convinced that Ezekiel is speaking God’s words when he proclaims on God’s behalf that ’the soul that sinneth it shall die; the son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son.’  And once more, whatever divine purpose gave the chosen people a priority among all peoples in knowledge of divine will and possession of divine favour, it is impossible to find any rule by which this priority shall for ever exclude all other peoples from being within the range of God’s manifested love; and conscience cannot but accept as a divine message that the Gentiles also shall come to the Heavenly ‘Light, and their kings to the brightness of His rising.’  So again, to turn from justice to mercy, we recognise that we are bound to spare pain to all creatures that can feel, and this duty can only be set aside by some higher duty which makes that pain the means to a higher moral end.  And if we are set by our consciences to seek for some rule of universal application for this purpose, it becomes perpetually clearer that nothing can excuse cruel punishments inflicted on criminals or enemies, or hard-hearted indifference to the poor and the weak.  Our own nature cries out for kindness in our pain, and that very cry from within compels our consciences to listen to the cry from without.  And the denunciations of cruelty and oppression we recognise as we hear them to be the voice of God.

But however true it be that this progress corresponds exactly throughout with the necessary working of the great moral principles implanted in the spiritual faculty, it nevertheless remains true also that all this teaching in its successive stages is given by men who did not profess to be working out a philosophical system, but who claimed to bring a message from God, to speak by His authority, and in many cases to be trusted with special powers in proof of possessing
