Gallicanism - the name given to the general theory that the Church, especially the Church in France, is free from the jurisdiction of the pope, while remaining Roman and Catholic - is familiar to most historians. The existence of such a thing as Anglo-Gallicanism, on the other hand, seems scarcely credible. Post-Reformation English Catholics present the image of a persecuted and retiring group of people, who, in order to preserve their corporate identity, became more Italianate in their culture than the Italians and in their theology more papalist than the popes; and of the majority of English Catholics this was true. But throughout their history there runs a thin red line of dissent, which passes from the Appellant priests in the late sixteenth century, via Blackloism in the seventeenth, to Charles Butler, Joseph Berington and the Catholic Committee at the dawn of emancipation. Gallicanism, and perhaps its English counterpart, were given a death-blow by Napoleon’s application of papal authority to the French bishops. But Anglo-Gallicanism was an unconscionably long time dying, for at Downside in the early nineteenth century William Bernard Ullathorne, later bishop of Birmingham, was taught theology from Gallican textbooks. In this tradition a prominent part, in terms of impact and literary output, was played by another Benedictine, Thomas Preston, alias Roger Widdrington.
