Answer 2

Thirteen of the twenty seven books of the New Testament are generally attributed to Paul. However, New Testament scholars dispute the authorship of some of the epistles,with nearly all saying that he did not write the two Epistles to Timothy and the Epistle to Titus. Many scholars also say that he did not write 2 Thessalonians, Colossians or Ephesians.

The seven undisputed letters of Paul are Romans, 1 Corinthians, 2 Corinthians, Philemon, Galatians, Philippiansand 1 Thessalonians.
