 In his last years, Luther continued to fight for his legacy, which included his mock-reluctant acceptance of an edition of his collected works to which he contributed an only partially reliable preface on which (as we have seen) some colourful but probably fictional stories of his life were to draw—though for all that it remains a revealing document. These years are marred by his vitriolic attacks on both Turks (and thus Islam) and Jews, in a marked change of tone from his earlier more considered and appreciative reflections, which had included That Jesus Christ was Born a Jew (1523)—although his positive remarks are based on hopes of Jewish conversion, while many of his comments in his unpublished lectures on Psalms had been hostile; partly because those hopes did not materialise, by 1538 Luther was writing Against the Sabbatarians, a polemic which he was to continue to the end of his life in further anti-Jewish  texts.[8]
