In this book, Paul's epistle is transliterated, translated and explained, showing his central themes of righteousness and justification by faith. The epistle relates to Paul's missionary activities in Galatia, where he had established assemblies of Gentile Christians with no requirement for Jewish practices. Paul's letter is a protest, the first declaration of his "apostle-ship", a rebuke to the Galatians for straying from the doctrine he had given them and a thinking through of that doctrine. The author also discusses the autobiographical details provided by Paul himself, the identity of the Galatians, the date of the epistle and the nature of Paul's opponents and reconstructs the situation which gave rise to the letter.
