[Chesterton] was content to have Frances manage his life.... His subservience to Frances may be seen as evidence of his gentle decency or alternatively as a weakness. Ingrams, I think, inclines to the latter view.But what of the ‘sins’ of the title? Here too it may be a question of weakness. Ingrams has Chesterton led astray, like a medieval king, by evil counsellors. There were two: his adored younger brother, Cecil, and his admired mentor Hilaire Belloc. Chesterton had a better mind and sharper intellect than either of them, as well as a kinder and more generous, if weaker, character.
It's mostly anti-Semitism, although anyone who has ever seen a picture of GKC might have thought of gluttony. In his defense, GKC lived before the depths of anti-Semitism were exposed; and the introductory version he bought on to is a form that masks a valid complaint that is severable from the Jews. "He felt that Jewish finance was corrupting Catholic Europe" is often described as a predecessor to the view that "loyalty to internationally-financed corporations undermines loyalty to one's own nation." You don't need any Jews to be involved to worry, for example, that Apple's or Nike's commitments to Communist China have worrying effects on our political culture here at home. You only even need 'the Chinese' accidentally; it could be any authoritarian nation with communistic values.
The reviewer continues:
I still read Belloc and Chesterton with pleasure. Few others seem to. Ingrams opines that only Chesterton’s Father Brown detective stories remain popular. This is probably true, though The Flying Inn, a fantastic novel about an Islamic takeover of England, has considerable vitality. (It’s not much use, I would add, to modern-day Islamophobes, Chesterton’s Islam being very different from theirs.) His book on Thomas Aquinas has been judged one of the best popular accounts of his philosophy. Chesterton is still admired in American Catholic universities, and a few years ago I was sent a copy of a French intellectual journal devoted entirely to Chesterton. All the same, today’s Catholic Church is very different from the one Belloc and Chesterton defended.
That last is certainly true, at least among the living. The Church believes in a metaphysical self, though, in which Chesterton himself is still a member -- and, hopefully, still praying for his beloved Ecclesia.
