Religion

What is in scope

Senior leadership of major religious institutions — diocesan bishops in episcopal traditions, presiding bishops in non-episcopal Protestant denominations, and equivalents in other religious traditions. The dataset's coverage is currently weighted toward the Anglican Communion, where the most recent transition is most fully documented.

Why this domain matters

Religion is the institutional category in this dataset with the most rigid selection-mechanism constraints. Doctrinal restrictions on who may hold sacramental authority — preaching, sacraments, governance of clergy — operate as binding rules that no nomination process can override. Changing these rules requires synodal, conciliar, or magisterial action, sometimes accompanied by parliamentary confirmation.

The Church of England's transition is a useful study because every step of the structural change is on the public record. The General Synod's 2014 measure permitting the consecration of women bishops, followed by the British Parliament's confirmation in October 2014, made first-woman appointments procedurally possible. Libby Lane was consecrated as Bishop of Stockport on 26 January 2015 — a span of roughly three months from rule change to first event. Rachel Treweek's diocesan appointment followed in mid-2015, and Sarah Mullally's appointment as Bishop of London in 2018. The pattern is mechanism-precedes-cluster in its cleanest form.

The Catholic Church remains the principal counterexample. The papacy and the College of Cardinals are doctrinally restricted to men; the structural change required to alter that has not occurred. The contrast between the Anglican and Catholic trajectories underlines the role of the doctrinal threshold.
