Biblical inerrancy
The WELS also agrees with the doctrine of Biblical inerrancy, the doctrine that the Bible is inspired by God and is without error (2 Timothy 3:16, 2 Peter 1:20-21, 1 Corinthians 2:13, John 17:17, Psalm 12:6, Titus 1:2). For this reason, they reject much of modern liberal theology.
