more, priest and bishop were no longer priest or bishop if they lived in mortal sin, and his definition of mortal sin was such as to render it scarce possible for any one to escape.[939] What his opinions were on the subject of clerical celibacy was a mooted point even shortly after his death. Thomas of Walden, the confessor of Henry V., in his _Doctrinale Fidei_, written to confute the errors of Lollardry, declares that he could not persuade himself that the Wickliffites derived from their leader their opposition to celibacy until he had recently read in Wickliffe’s Sermon on Midsummer Eve the passage which says that “prestis ben dowid and wyflees agens Goddis autorite.... And this is the caste of the fend to kyndle fir in heerdis” &c.,[940] and Mr. Arnold, the latest editor of Wickliffe, seems to entertain no doubt as to the authenticity of the text, or of the views of the reformer as expressed there, and in other passages of tracts attributed to him.[941] Yet had Wickliffe taught this doctrine it would have been as widely known as his other errors, it would have been condemned in the repeated proceedings taken against him and his teachings, and it would not have been left for Thomas of Walden to discover it in one of the numerous sermons which passed from hand to hand as the works of the heresiarch. Wickliffe was too earnest and sincere in his convictions to leave anyone in doubt as to his belief on any point that he thought worth discussion. What his views were on this subject can perhaps best be sought in the most mature of his works, the Trialogus, the authenticity of which I believe is indisputable. No one can read the chapters on Sensuality and Chastity without seeing that the whole line of argument is directed towards proving the superiority of virginity over marriage, even to the fanciful etymology of “cœlibatus” from the state of the “beati in cælo;” while in the chapter on the riches of the clergy, they are regarded as virgins betrothed to Christ, and the vow of chastity which they take is likened to their similar vow of poverty, and not to be infringed.[942] Wickliffe’s austerity, in fact, was deeply tinged with asceticism, and in aiming to restore the primitive simplicity of the church, he had no thought of relegating its ministers to the carnalities of family life, which would render impossible the Apostolic poverty that was his ideal. Even the laity, in his scheme, were to be so rendered superior to the lusts of the flesh that he pronounced those who married from any other motive than that of having offspring to be not truly married.[943] He evidently had no intention to interfere with clerical celibacy, and the passages which have been cited to the contrary may safely be regarded as supposititious. Either the writings in which they occur have been erroneously ascribed to Wickliffe, or the passages themselves have been interpolated by too zealous disciples, eager to procure the authority of the master for the later development
