Definition
The Lords Spiritual are the senior bishops of the Church of England who hold seats in the House of Lords by virtue of their ecclesiastical office, not by hereditary peerage or royal appointment to a life peerage. They form one of the two components of the House of Lords, the other being the Lords Temporal. The Lords Spiritual represent the formal constitutional union of church and state in England and are a feature unique to the English (and, by extension, British) constitutional order.
In their parliamentary capacity, the Lords Spiritual may debate and vote on legislation, participate in select committees, and contribute to the scrutiny of government. They are not peers in the strict sense — they hold their seats ex officio and lose them upon vacating their bishoprics.
Common Confusion
LORDS SPIRITUAL vs. LORDS TEMPORAL: These two categories together constitute the membership of the House of Lords (alongside, in modern practice, life peers and formerly hereditary peers). The distinction is simple but worth stating clearly: Lords Spiritual hold seats by reason of ecclesiastical office; Lords Temporal hold seats by reason of peerage — whether hereditary, life, or by royal creation. Confusion arises in older texts that use "Lords" without qualification, leaving the reader to determine which class is intended from context.
LORDS SPIRITUAL vs. THE BENCH OF BISHOPS: The Bench of Bishops refers to the bishops of the Church of England as a collective body within their ecclesiastical governance structure. Not all bishops sit in the House of Lords. The Lords Spiritual are a subset — the most senior archbishops and bishops entitled to parliamentary seats. In historical research, the terms are sometimes used interchangeably but are not identical.
Recognized Forms
/SUBTYPES
The Lords Spiritual have a fixed internal hierarchy reflecting the seniority of sees:
The Archbishops of Canterbury and York hold permanent seats. The Bishops of London, Durham, and Winchester hold permanent seats by virtue of the historic seniority of those sees. The remaining 21 seats rotate among the other diocesan bishops of the Church of England in order of seniority of consecration.
Why It Matters in Research
For researchers working in English constitutional history, ecclesiastical law, or the history of Parliament, this term is foundational. Several navigational cautions apply.
The composition has changed over time. Before the Reformation, the Lords Spiritual included not only bishops but abbots and priors — heads of major monastic houses. The dissolution of the monasteries under Henry VIII permanently altered the character of the Lords Spiritual. Sources predating the mid-sixteenth century use the term to describe a substantially larger and differently constituted group. Do not read pre-Reformation usage through a post-Reformation lens.
Welsh and Irish bishops complicate the picture. After Welsh dioceses were brought under the Church of England, Welsh bishops became eligible for seats. After the Acts of Union with Ireland (1800) and the later disestablishment of the Church of Ireland (1869), Irish bishops lost their parliamentary representation. Scottish bishops were never included, as the Church of Scotland is Presbyterian and has no established episcopal hierarchy. Researchers must therefore be careful about which bishops are being discussed and in which historical period.
The Bishoprics Act 1878 fixed the number of episcopal seats at 26, establishing the rotating seniority system still in use. Before this, the number fluctuated as new dioceses were created. Texts from between the early nineteenth century and 1878 may describe a transitional and sometimes contested arrangement.
The Lords Spiritual continue to play an occasional substantive role in modern legislation, particularly on matters of conscience, religious liberty, and social ethics. Researchers tracking legislative history on these subjects should not overlook their contributions in Hansard and committee records.
Historical Dictionary Support
The three source dictionaries offer terse but consistent definitions. Black's defines the Lords Spiritual as "the archbishops and bishops who have seats in the house of lords," stopping there. Rapalje & Lawrence is equally brief, defining the term in the same language while appending a paired definition of Lords Temporal in the same entry — a useful juxtaposition confirming that the two categories were understood as a natural pair. Bouvier's entry is a stub, directing the reader to Parliament, which reflects Bouvier's orientation toward American law and its limited engagement with distinctly English constitutional machinery.
None of the source dictionaries addresses the pre-Reformation composition, the rotating seniority system, or the exclusion of Scottish and (after disestablishment) Irish bishops. Wiktionary's definition — "the 26 bishops of the Church of England who serve in the House of Lords" — is accurate for the modern period but would mislead a researcher working in earlier sources. All definitions should be treated as snapshots of the post-1878 settled arrangement, not as descriptions of the term across its full historical range.
Jurisdictional Note
This term is specific to English and British constitutional law and has no direct counterpart in other common law jurisdictions. The United States Constitution explicitly prohibits any religious test for office and contains no established church, making the concept structurally inapplicable. Researchers in Commonwealth jurisdictions may encounter the term in historical materials relating to colonial governance or appeals to the Privy Council, but the Lords Spiritual had no formal role in those proceedings.
