In Gal, how do we know Paul wrote the book of Galatians?
There are at least two reasons. 1. Paul says so in Galatians 6:11. We trust this is correct because no one in the early church ever questioned this. God promised to preserve His word in Isaiah 55:10-11; 59:21; 1 Peter 1:24-25; Matthew 24:35. 2. Tertullian (200-240 A.D.) in Against Praxeas ch.28 also says the Paul wrote to the Galatians. See also the next question for more info. Q: What evidence do we have that the book of Galatians should be in the Bible? A: There are at least four reasons. 1. Paul wrote it, and He was an apostle. Peter attested that Pauls words were scripture in 2 Peter 3:15-16. 2. Paul himself said he was apostle in 1 Timothy 1:1; 2:7, Romans 1:1; 1 Corinthians 1:1; 9:1, 2 Corinthians 1:1, 11:5; Galatians 1:1, Ephesians 1:1; Colossians 1:1; 1 Timothy 1:1; 2 Timothy 1:1; Titus 1:1. 3. Evidence of the early church. See the next question for some of the writers who referred to verses in Galatians. 4. Tertullian said Paul wrote to the Galatians in Tertullian Against Marc
