THE writings of the seventeenth-century English theologian, Henry Holden, played a small but significant part in the development of western religious thought in the centuries following his death. His most important work, Divinae fidei analysis, first printed in Latin at Paris in 1652 and afterwards translated and published in English, was several times reprinted in the seventeenth and eighteenth centuries and was later incorporated in two theological collections, J. P. Migne's Theologiae cursus completus (tom.6, 1839), and Josef Braun's Bibliotheca regularum fidei (tom.2, 1844). It influenced the thinking, in the nineteenth century, not only of avowed liberals such as Dôllinger and Acton, but also, in some degree, of moderate progressives like Newman. In recent years, specialist studies on different aspects of Holden's thought have appeared in English and in French. So far, however, no serious attempt has been made to revise his bibliography: we still have to rely, in large measure, on that published by Joseph Gillow more than a century ago. In this article I want to bring together material that has come to light since Gillow's time and to examine Holden's works afresh against the background of his life and the religious and political developments in England and France at that period. I shall devote particular attention to two themes that run through all his work. One is gallicanism, that amalgam of mediaeval theories limiting the authority of the papacy in relation to secular states and their rulers and national churches and their bishops. It will be seen that plans which Holden advanced in the 1640s for the reform of the Catholic Church in England along gallican lines are based largely on ideas developed in his Divinaefidei analysis published a few years later. The other is his analytical and critical approach to doctrine, aiming always to distinguish truths solidly based on Scripture and tradition from the mere speculations of theologians. It is an approach that had been made popular in France by the Catholic controversialist, François Véron, whose Régula fidei catholicae was first published at Paris in 1644 when Holden was probably already at work on his Divinae fidei analysis. It reveals itself in all Holden's writings and distinguishes him from many of the other Catholic apologists who were drawn into controversy with the Anglican divines of the post-Chillingworth era.
