This article takes the opportunity of Gillis Harp's recent biography of nineteenth-century American Episcopalian Phillips Brooks to engage Harp's theological situation of the Episcopal Church. Harp's revisionist historiographical argument, rejecting the Broad Church ‘myth of synthesis’ for a more agonized tale of trenchant party battles, is welcome for its perceptiveness and depth of analysis, not least as these historical difficulties remain at the centre of contemporary intra-Anglican and ecumenical conversations. Harp's commitment to a ‘Reformed’ and ‘evangelical’ Anglicanism, however, raises a series of questions – concerning the nature of orthodoxy and Christian doctrine, as well as ‘Protestant’ identity – that deserve greater investigation, and that historians and theologians would do well to pursue together.
