Definition
A religious sect is a body or number of persons united in shared tenets but constituting a distinct organization or party by holding doctrines or sentiments that differ from those of other sects or of the broader religious public. The term does not carry a fixed statutory definition but appears in constitutional, tax, and regulatory law primarily in the context of religious liberty, tax exemption, and the Establishment Clause. A sect is distinguished from a church or denomination chiefly by emphasis on its distinctiveness from a parent tradition, though in modern legal usage the terms are often used interchangeably without strict technical differentiation.
Common Language
Modern common usage (Wiktionary): An ancient astrological concept designating heavenly bodies as either diurnal or nocturnal — a meaning entirely disconnected from legal usage and largely obsolete in general discourse as well.
Historical common usage (Webster's 1913): "A cutting; a scion." Marked as obsolete even in 1913.
The ordinary English word "sect" as most readers understand it — a religious group with distinctive beliefs — maps reasonably well onto the legal usage. However, neither historical dictionary definition captures this common understanding, suggesting both sources were recording archaic or specialized senses. The operative everyday meaning, and the legal meaning, both derive from broader usage that Webster's 1913 and Wiktionary happen not to have foregrounded. Researchers should note that legal dictionaries carry more useful definitional weight here than general dictionaries.
Common Confusion
Sect, denomination, church, and religious organization are used interchangeably in many legal instruments and judicial opinions, but they carry different connotations. "Church" in tax law (e.g., under the Internal Revenue Code) has developed a specific multi-factor meaning that does not automatically apply to a "sect." A sect may or may not qualify as a church for tax exemption purposes; the analysis is distinct. Researchers conflating these terms may miss relevant doctrine. "Sectarian" as an adjective has developed independent legal significance, particularly in public funding and education law, and should be researched separately.
Why It Matters in Research
The legal significance of "sect" is almost entirely derivative — the term gains traction from its role in constitutional and statutory provisions governing religion rather than from any freestanding legal doctrine of its own. Key research implications:
First, the definition offered by Black's (both editions) traces directly to State v. Hallock, 16 Nev. 385, a nineteenth-century state court decision. That single case citation forms the backbone of both editions' definitions. Researchers should treat this not as settled universal doctrine but as illustrative judicial language from a specific historical and jurisdictional context.
Second, the term appears in older state constitutional provisions — particularly those prohibiting public funding of "sectarian" institutions — where "sect" and "sectarian" carry distinct political and anti-Catholic historical overtones from the Blaine Amendment era. Understanding this history is essential when researching nineteenth and early twentieth century state constitutional litigation.
Third, in federal law, "sect" appears in conscientious objector provisions (historically in Selective Service contexts) and in statutory religious exemptions. Courts have generally declined to privilege established sects over newer or less-organized religious groups, a development driven by First Amendment equality principles that post-date most historical dictionary entries on this term.
Fourth, Anderson's Dictionary of Law offers no independent definition, instead cross-referencing RELIGION and SECTARIAN. This signals that "sect" was treated as a term understood by context rather than a technical legal term requiring independent definition — a useful research indicator that the action is in adjacent entries.
Historical Dictionary Support
Black's Law Dictionary (1st and 2nd editions) offer virtually identical definitions, both anchored to State v. Hallock, 16 Nev. 385. The definition is descriptive rather than normative: a group united in tenets but distinguished by doctrinal difference from others. Neither edition attempts to distinguish sect from denomination, church, or religious society, reflecting the relative underdevelopment of religious liberty doctrine at the time of their publication.
Anderson's Dictionary of Law declines to define the term independently, a notable editorial choice suggesting that practitioners of the era were expected to derive meaning from context and from adjacent entries on religion and sectarian matters.
No historical dictionary entry addresses the constitutional dimensions that came to dominate the term's legal significance in the twentieth century — particularly Establishment Clause doctrine, tax exemption criteria, and free exercise jurisprudence. Historical sources are therefore useful for understanding how courts used the word descriptively in the nineteenth century but are inadequate guides to how "sect" functions in modern legal research.
Jurisdictional Note
State constitutional provisions vary considerably in their use of "sect" and "sectarian," particularly in the context of public education funding. States with Blaine Amendment-era provisions may apply the term more restrictively than federal constitutional doctrine requires. Researchers working on state-level religious liberty or public funding questions should not assume that federal interpretations of "sect" translate directly to state constitutional analysis.
