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.
