The movement claim that the common law is 'founded upon the Holy Bible' — making biblical authority a structural source of operative American law — is partially supported as 19th-century historical doctrine and foreclosed as modern operative claim
The movement proposition
A claim recurring in Byron Beers’s Treatise 2 (Liberty) and elaborated across the corpus runs: the common law of the United States is “founded upon the Holy Bible.” Beers cites several 19th-century state court cases — Wylly v. Collins, 9 Ga. 223 (1850); Updegraph v. Commonwealth, 11 Serg. & Rawle 394 (Pa. 1824); Shover v. State, 10 Ark. 259 (1850) — and the U.S. Supreme Court’s Vidal v. Girard’s Executors, 43 U.S. (2 How.) 127 (1844). The cases, on Beers’s account, treat Christianity (or biblical authority more broadly) as a structural component of the common law, not as background motivation. The claim is that operative American law inherits this biblical foundation.
The proposition is offered as a historical-doctrinal fact that bears on contemporary legal analysis. If the common law is founded on the Bible, then on Beers’s framework biblical authority remains a source of legal content — not a separate religious morality alongside law, but a substantive layer of law itself.
The historical record
The 19th-century state-court cases Beers cites are real and do contain language treating Christianity as part of the common law. The principal context is blasphemy prosecution. In Updegraph v. Commonwealth, the Pennsylvania Supreme Court upheld Abner Updegraph’s conviction for public blasphemy by reasoning that Christianity was part of Pennsylvania’s common law and that the common law therefore supported the state’s criminal statute against blasphemy. Wylly v. Collins and Shover v. State appear in similar postures in their respective state-court records — Christianity as part of the common law operating to sustain specific 19th-century state-court holdings, principally around blasphemy and Sabbath-observance prosecutions.
The U.S. Supreme Court touched this terrain in Vidal v. Girard’s Executors. Stephen Girard’s will left approximately two million dollars to establish a Philadelphia orphans’ college on the condition that “no ecclesiastic, missionary, or minister of any sect whatsoever, shall ever hold or exercise any station or duty whatever in the said College; nor shall any such person ever be admitted for any purpose, or as a visitor, within the premises appropriated to the purposes of the said College.” Girard’s heirs challenged the bequest as void for being anti-Christian. Justice Story’s opinion for a unanimous Court upheld the bequest. In doing so, the Court accepted that Christianity was part of Pennsylvania’s common law in a qualified sense — enough to sustain blasphemy prosecutions, not enough to invalidate a clergy-excluding charitable bequest.
The verbatim Cornell LII text of Vidal contains the language (see verification log V08):
“Christianity is a part of the law of Pennsylvania, so that blasphemy can be punished, but not for the purpose of invading the conscience of other persons…”
This is the language Beers cites. As the verification log records, the language appears as a concession the Court grants en route to ruling against the party invoking it. The “Christianity is part of the common law” formulation was the heirs’ predicate for arguing the bequest was void; the Court accepted the predicate but found it insufficient to support the conclusion the heirs wanted. The case actually upheld the clergy-excluding institution.
The historical fact — that 19th-century American courts treated Christianity as part of the common law in specific narrow contexts (principally blasphemy prosecutions) — is correct. That fact is partially supported by the cases.
What the historical record does not establish
The cases do not, on their own terms, support the broader proposition that biblical authority is a structural source of currently operative American law. Three reasons:
First, the scope of the 19th-century holdings is narrow. Vidal expressly limited the “Christianity is part of the common law” formulation to specific contexts — sustaining blasphemy laws as not violating then-extant constitutional provisions — and rejected the broader Christian-establishment inference the Vidal heirs were arguing for. The state-court blasphemy cases operate in their own narrow doctrinal contexts. None of these cases held that biblical authority generally controls common-law content beyond the specific blasphemy-and-Sabbath terrain.
Second, the constitutional landscape has been comprehensively reshaped. The First Amendment’s religion clauses were not understood to apply to the states until Cantwell v. Connecticut, 310 U.S. 296 (1940), incorporated the Free Exercise Clause, and Everson v. Board of Education, 330 U.S. 1 (1947), incorporated the Establishment Clause. Once incorporated, the Establishment Clause did substantial doctrinal work on the religion-and-law relationship. The blasphemy-prosecution line that supported the 19th-century cases would not survive modern Establishment Clause analysis (see, e.g., Joseph Burstyn, Inc. v. Wilson, 343 U.S. 495 (1952), striking down sacrilege prosecutions under the First Amendment’s free-speech provisions; the doctrinal climate that supported state-level blasphemy laws was largely gone by the 1960s). The Lemon v. Kurtzman, 403 U.S. 602 (1971), framework (since refined and partially supplanted, most recently by Kennedy v. Bremerton School District, 597 U.S. ___ (2022)) operates as a constitutional check on state efforts to make religious authority a source of state law.
Third, the modern American legal mainstream does not treat biblical authority as a source of common-law content. The Restatements, the Uniform Commercial Code, modern tort and contract treatises, modern statutory interpretation methodology — none of these treat biblical text as legal authority. Common law in operative modern practice is the body of judicial gloss on state and federal text, plus the residual judicially-developed doctrines (contract, tort, property, equity) that survive in state law. The 19th-century formulation that Christianity is “part of the common law” survives as a doctrinal artifact, not as a source of currently operative content.
What follows for Beers’s structural claim
Beers’s framework treats the 19th-century formulation as still operative. The framework needs the biblical-foundation claim to operate, because the natural-order half of the framework’s master binary rests on common law as the operating procedural mechanism, and Beers ties common-law content to biblical authority. If the 19th-century formulation is a historical artifact rather than operative content, then the natural-order half of the framework loses much of its doctrinal anchorage. The common law that exists today does not derive its operative content from biblical text in any way the modern legal system recognizes.
A reader sympathetic to Beers’s framework might respond that the modern legal system’s failure to recognize biblical authority is itself the unnatural-order condition the framework describes — that the displacement of biblical authority from operative law is the conversion-event consequence rather than evidence against the framework. The response is consistent with how the framework operates internally, but it relocates the question from “is the claim historically supported” to “is the framework’s totalizing self-confirmation a feature or a bug.” The latter is a methodological question, not a doctrinal one. As a doctrinal matter, the operative modern claim is foreclosed.
Verdict
Partially supported. The historical claim — that 19th-century American courts treated Christianity as part of the common law in specific narrow contexts — is correct, with the qualifying observations that (a) the scope of those holdings is narrow (principally blasphemy and Sabbath observance, with Vidal showing the limits even at the Supreme Court level), and (b) one of the principal cited cases (Vidal) actually rejected the broader Christian-establishment inference the cited language is sometimes offered to support.
The operative modern claim — that biblical authority remains a structural source of currently binding American law — is foreclosed by the post-incorporation Establishment Clause doctrine, by the modern mainstream of American legal methodology, and by the actual scope of the 19th-century holdings on which the claim rests. The two halves of the proposition should not be conflated, and this finding distinguishes them deliberately.
The three state-court citations in the historical-half analysis (Wylly v. Collins, Updegraph v. Commonwealth, Shover v. State) carry forward to the citation validator as unverified — the primary-source text was not retrievable from open-access sources in this triage cycle. The historical-doctrine half of the finding does not depend exclusively on those cases (the Vidal verification carries substantial weight), but the cases should be pulled from Westlaw, HeinOnline, or state reporters before publication.
