Both men were keen searchers--each in his own way--after religious truth. For both it was a subject that practically affected their whole lives. But while in Martineau the result was a deep theology which found its satisfaction in the fold of Unitarianism, in Newman dogma of any sort was practically an unknown quantity. He drifted further and further from revealed religion, until many of his letters and writings became to the Christian minds of some who read them exceedingly painful. It is true that before he died Mr. Temperley Grey, the minister who attended him in his last illness, declared that there was a return to his original faith, but still nothing can alter the effect of the written word, and there is a passage in one of Newman's own letters which illustrates this fact very clearly. "It is a sad thing to have printed erroneous fact. I have three or four times contradicted and renounced a passage ... _but I cannot reach those whom I have misled_." In those last nine words there is a world of unexpressed regret--regret which no after endeavour can eradicate. Both spoken and written words go to far mental ports, and very often-from being out of our ken--unreachable ones for us. No later contradiction can reach them and undo the once-made impression. Martineau and Newman were not of one mind in the matter of religion. The letters which passed between them show that; but they show, too, that no dispute separated them. If for a time some painful passage in a letter of Newman's troubled his friend, the matter was dealt with with straightforward candour and unfailing forbearance and gentleness. There were no harsh words between them. Both of them were naturally, innately sweet and kindly in disposition. Even in matters of dispute which concerned that subject which occupied so large a part in both their minds, difference of opinion could not "separate very friends." It will be remembered that the year before the regular correspondence between the two began, Martineau had written a paper criticizing Newman's _Phases of Faith_. Before giving Newman's letters, perhaps a few words on Martineau himself would not be out of place here. He came of an old Huguenot family. Mr. Jackson, from whose biography of him I am quoting, says that Gaston Martineau, who, tradition tells us, was a surgeon of Dieppe, came to England after the Revocation of the Edict of Nantes in 1685, and that though first he went to London to live, yet that eventually he settled down at Norwich, and here all his children were born. The youngest of them became the father of James Martineau, the theologian. He was born in the same year as Francis Newman, and died just seven years before he did.
