Q. Where can I find information on the Pauline Epistles?

Paul, Paul of Tarsus, wrote several books of the Bible. There is quite a bit written about Paul, and the books of the Bible that he is believed to have written. 

For background information, you may review the e-book, The Pauline Epistles, by Muddiman, John, et al. Updated Selection. Oxford University Press, 2010.

You might also consider focusing on a specific letter, such as Romans, 1 & 2 Corinthians, or 1 & 2 Thessalonians.
