What does Scripture alone mean in Christian theology?

The concept of Scripture alone asserts that the Bible is the sole authoritative source for Christian doctrine and practice. This principle maintains that God's Word is divinely inspired and preserved, making it the definitive guide for understanding truth and salvation. As 2 Timothy 3:16-17 indicates, all Scripture is God-breathed and equips believers for every good work. Thus, Christians rely solely on the teachings of the Bible for their faith, without the need for additional human traditions or teachings to dictate their beliefs.
