Biblical infallibility is the belief that the Bible can be relied on entirely for guidance in faith and Christian living, providing accurate and trustworthy direction for salvation and spiritual practice.

Historically, Jewish and Christian interpreters have treated the Bible as trustworthy, though trust did not necessarily imply historical or scientific accuracy. The concept of biblical infallibility gained prominence in 19th- and early 20th-century Protestantism as a fundamentalist reaction against modernist trends in mainstream Christianity. In parallel, the Catholic Church developed the idea of papal infallibility, while evangelical churches emphasized the infallibility of Scripture. Both movements combined theological claims with ideological resistance to perceived erosion of traditional authority, reflecting a broader crisis in Western religious authority.

Early Christian writers, such as Clement of Rome, emphasized the truthfulness of Scripture, attributing its teachings to divine inspiration and highlighting the moral endurance of the righteous. Denominational perspectives vary: the Catholic Church teaches the inerrancy of Scripture in matters of salvation but requires careful interpretation of the human authors’ intentions. Methodists, following John Wesley, regard Scripture as infallibly true and authoritative for faith and practice, though not equating the Bible itself with God. Evangelical views, particularly in the U.S., often uphold both inerrancy and infallibility, while many international evangelicals focus only on God’s infallibility rather than that of the Bible.

The concepts of infallibility and inerrancy are related but distinct. Infallibility refers to the Bible’s inability to fail in matters of faith and practice, while inerrancy denotes freedom from all errors, including historical or scientific details. Some denominations allow for minor errors in non-essential historical or scientific details under infallibility, whereas inerrancy traditionally holds that all original manuscript content is fully true. This distinction has led to ongoing debates among scholars and denominations, with documents like the Chicago Statement on Biblical Inerrancy affirming that infallibility and inerrancy are closely connected but not identical, and that scientific interpretations should not override scriptural teachings on creation and divine events.

Background

Historically, Jewish and Christian interpreters of the Bible have seen it as reliable and trustworthy, but such views do not equate veracity with historicity, scientificity or even facticity. The idea of biblical infallibility gained ground in Protestant churches as a fundamentalist reaction against a general movement towards modernism within mainstream Christian denominations in the 19th and early 20th centuries.

In the Catholic church, the reaction produced the concept of papal infallibility whereas, in the evangelical churches, the infallibility of the Bible was asserted. "Both movements represent a synthesis of a theological position and an ideological-political stance against the erosion of traditional authorities. Both are antimoderne and literalist."

<blockquote>No matter how little common ground was apparent at the time between Roman Catholicism and the Evangelical Right, these two reformulations of scriptural and papal supremacy represented a defiant assertiveness in reaction against the crisis of religious authority that was engulfing Western religion.</blockquote>

Patristic

Clement of Rome in his Letter to the Corinthians says:

:1Clem 45:1-5:

: You are contentious, brethren, and zealous for the things which lead to salvation. You have studied the Holy Scriptures, which are true, and given by the Holy Spirit. You know that nothing unjust or counterfeit is written in them. You will not find that the righteous have been cast out by holy men. The righteous were persecuted, but it was by the wicked. They were put in prison; but it was by the unholy. They were stoned by law-breakers, they were killed by men who had conceived foul and unrighteous envy. These things they suffered, and gained glory by their endurance.

Denominational positions

Catholicism

The Catholic Church does not claim infallibility of scripture, instead asserting freedom from error, holding "the doctrine of the inerrancy of Scripture". The Second Vatican Council, citing earlier declarations, stated: "Since everything asserted by the inspired authors or sacred writers must be held to be asserted by the Holy Spirit, it follows that the books of Scripture must be acknowledged as teaching solidly, faithfully and without error that truth which God wanted put into sacred writings for the sake of salvation." It added: "Since God speaks in Sacred Scripture through men in human fashion, the interpreter of Sacred Scripture, in order to see clearly what God wanted to communicate to us, should carefully investigate what meaning the sacred writers really intended, and what God wanted to manifest by means of their words."

Methodism

The Methodist theologian Thomas A. Lambrecht notes that John Wesley, the founder of Methodism,

As such, Lambrecht notes that "orthodox, evangelical, and traditionalist United Methodists believe in the 'infallibility' of Scripture."

Lambrecht, therefore, writes that:
