Of the thirteen epistles accepted by tradition as Pauline, the opinion among scholars are divided as to their authenticity.
The question of authenticity is not a straightforward one for its considerations include intangibles such as style, form and content.
 We will therefore be accepting the general consensus as depicted in Table A above.
There is a strong, and very likely authentic, tradition that Paul died in the Neronian persecution of Christians in AD64.
 It is therefore reasonably certain that the genuine epistles must all be written before, or at the latest in, AD64.
Fundamentalists, who cannot accept anything else, assert that all the thirteen epistles attributed to him by the New Testament are genuinely his.
And then there are scholars of a more skeptical bent that accept only four of the thirteen epistles are being actually written by the historical Paul. As the arguments in this chapter will be taken only from those epistles accepted as genuine by most scholars, it is important to present the reasons why these epistles are accepted as such while others are rejected as authentic.
Eras'tus, the city treasurer, and our brother Quartus, greet you. If any one has no love for the Lord, let him be accursed. This short ending is even more suspicious when we find out that Paul spent about three years in Ephesus (Acts -19:1; 19:8-10).
I Corinthians -24 The churches of Asia send greetings. We would expect him to be on more familiar terms with the Ephesians.
We can connect some statements found in this epistle with some events depicted in Acts.
In chapter seventeen of Acts we are told that Paul's visit to Thessalonika was not without trouble.
I Tertius, the writer of this letter, greet you in the Lord. I have sent him to you for this very purpose, that you may know how we are, and that he may encourage your hearts.
Ga'ius, who is host to me and to the whole church, greets you. Peace be to the brethren, and love with faith, from God the Father and the Lord Jesus Christ.
 Table A below summarizes the bulk of present scholarly opinion about the authorship of these epistles. Some scholars still believe in the possibility that Collosians could be an authentic Pauline document. The theology of the pastorals are significantly different from the genuine Pauline epistles.
