The sermons of John Donne are seen to embody the tensions and pressure on public religious discourse 1621 - 25. This book considers the professional contribution of John Donne to an emerging homiletic public sphere in the last years of the Jacobean English Church (1621-25), arguing that his sermons embody the conflicts, tensions, and pressures on public religious discourse in this period; while they are in no way typical of any particular preaching agenda or style, they articulate these crises in their most complex forms and expose fault lines in the late JacobeanChurch. The study is framed by Donne's two most pointed contributions to the public sphere: his sermon defending James I's Directions to Preachers and his first sermon preached before Charles I in 1625. These two sermons emerge from the crises of controversy, censorship, and identity that converged in the late Jacobean period, and mark Donne's clearest professional interventions in the public debate about the nature and direction of the Church of England. In them, Donne interrogates the boundaries of the public sphere and of his conformity to the institutions, authorities, and traditions governing public debate in that sphere, modelling for his audience an actively engagedconformist identity.
