Manning Clark is regarded as a pioneer of Australian national history. His output has been unequalled but it has provoked a vigorous division of opinions concerning its accuracy and the all-pervading thesis that Australia, to achieve its true national self-perception, must throw off the British heritage that included the baleful influence of the Anglicanism in which Clark was raised by his priest father. Here the work of three key scholarly critics, namely Dr George Shaw, Professor Brian Fletcher and Professor Alan Atkinson is evaluated, all of whom are Anglican historians of Australia. They have made very different assessments of the evolution of Australian national identity and the permanence of the British heritage. Shaw, as a former student of Clark, has assessed his mentor’s work not as rigorous history but essentially as ‘sentimental humanism’. As well, the opportunity is taken to reflect on the two extensive biographies of Clark, namely by Brian Matthews and Mark McKenna. Both these men were educated as Roman Catholics at a time when Rome was decidedly allergic to the idea of ecumenical outreach. Consequently, it is argued here that an accurate assessment of Manning Clark’s oeuvre is yet to be accomplished.
