The WELS believes that the entire Bible is God's Word, inspired and inerrant (cf. 2 Timothy 3:16). The Bible teaches us that sin has corrupted all (cf. Romans 3:23) and that a Savior from sin is vital to eternal security in heaven (cf. 2 Corinthians 5:21). This Savior is found in Christ and is given to us by God (cf. Ephesians 2:8-9). The faith which trusts this is created in us by the Holy Spirit working through God's Word (cf. Romans 10:17).
WELS pastors are trained in the Biblical languages of Greek and Hebrew, which enables them to study God's Word in its original texts. WELS churches strive to teach what God said, not what we think he meant. We believe that the Bible speaks for and interprets itself.
