In early 1641 Ussher developed a mediatory position on church government, which sought to bridge the gap between the Laudians, who believed in an episcopalian church hierarchy (bishops), and the Presbyterians, who wanted to abolish episcopacy entirely. His proposals, not published until 1656, after his death, as The Reduction of Episcopacy, proposed a compromise where bishops operated in a Presbyterian synodal system, were initially designed to support a rapprochement between Charles and the parliamentarian leadership in 1641, but were rejected by the King. They did, however, have an afterlife, being published in England and Scotland well into the eighteenth century. In all, he wrote or edited five books relating to episcopacy; the last two, treatises on the Ignatian epistles, were particular scholarly achievements that have largely survived modern scrutiny.
