Biblical inerrancy is the doctrine that the Bible, in its original manuscripts, contains no errors - whether in matters of theology, history, science, or any other domain. It is a position held within certain strands of Christianity, particularly within conservative Protestant traditions, and stands as one of the more contested doctrines in Christian theology and biblical scholarship. The related but distinct doctrine of biblical infallibility holds that the Bible is without error only in matters of faith and practice, not necessarily in historical or scientific claims. The two terms are sometimes used interchangeably in popular usage, though theologians generally distinguish them.

Inerrancy is not a single, uniform position. Proponents differ on what counts as an error, how to handle apparent contradictions, and how to interpret passages that conflict with findings from history, archaeology, or natural science. The Chicago Statement on Biblical Inerrancy (1978) is the most widely cited formal definition among inerrantists, asserting that inerrancy applies to the autographs (original manuscripts, none of which survive) and must be interpreted in light of the literary genre and intent of each passage. Critics argue this formulation makes the doctrine unfalsifiable, since no original manuscripts exist against which to test it. Inerrantists respond that the doctrine is grounded not in direct access to autographs but in the reliability of textual transmission and the convergent evidence of manuscript traditions, making the absence of originals a practical rather than a logical obstacle.

Several categories of inerrancy are distinguished in the literature:

• Absolute (strict) inerrancy - the Bible is accurate in every detail, including historical and scientific claims read plainly.
• Limited (partial) inerrancy - the Bible is inerrant only in its theological and soteriological claims.
• Inerrancy with accommodation - biblical authors used the scientific and historical knowledge of their day; apparent errors reflect accommodation to human understanding rather than falsehood.
• Infallibility without inerrancy - the Bible reliably guides believers to salvation and right living but may contain factual errors in other domains.

The explicit formulation of inerrancy as a doctrinal category is largely a modern development, arising most sharply in response to Enlightenment biblical criticism and the historical-critical method. Earlier Christian thinkers, including Augustine and Aquinas, held high views of scriptural authority but did not systematize inerrancy in the modern sense. The doctrine became a defining marker in Protestant fundamentalism in the late 19th and early 20th centuries, particularly in the United States, in part as a response to Darwinism and higher criticism. See Biblical Inerrancy - History for fuller treatment.

Within Christian theology, inerrancy remains contested. Mainline Protestant denominations and the Catholic Church generally do not affirm strict inerrancy, while many evangelical and fundamentalist denominations treat it as a foundational commitment. Eastern Orthodoxy holds a high view of scriptural authority but does not map neatly onto either inerrancy or infallibility as defined in Western Protestant categories; see Eastern Orthodox View of Scripture for fuller treatment. The evangelical scholarly consensus centers on something close to the Chicago Statement, though evangelical scholars debate its application.

Secular biblical scholarship, operating under the historical-critical method, generally does not treat inerrancy as a viable academic framework, arguing that the documentary evidence points to human authorship, editorial revision, and internal contradiction. Inerrantists respond that the historical-critical method carries its own methodological assumptions that are not religiously neutral.

Apparent conflicts with natural science - heliocentrism, the age of the earth, biological evolution - have been particular flashpoints. Protestant viewpoints on heliocentrism illustrate how the debate has played out historically on one such question. Similar debates continue around cosmology, geology, and biology.

There is no single cross-denominational theological consensus on inerrancy. Within evangelical Protestantism, a qualified scholarly consensus supports something close to the Chicago Statement, though it is contested even there. See Biblical Inerrancy - Evangelical Consensus and Biblical Inerrancy - Biblical Scholarship Consensus for domain-specific summaries.

• Strict Inerrancy - The Bible is without error in every detail, including history and science, when properly interpreted.
• Limited Inerrancy - The Bible is inerrant in theological and moral teaching but not necessarily in historical or scientific claims.
• Infallibility Without Inerrancy - The Bible reliably accomplishes its purpose of guiding believers but may contain factual errors in non-theological domains.
• Critical Rejection - The doctrine of inerrancy is historically late, exegetically untenable, and incompatible with the findings of historical-critical scholarship.
• Neo-Orthodox View - The Bible is the word of God insofar as it witnesses to divine revelation, but its human character means it is not inerrant in the strict sense.
