The Pauline Corpus of Modern Scholars and Marcion

Modern bible “scholars” claim that certain Pauline epistles were not written by Paul but were later pseudepigraphal works.

The seven letters they “consider genuine” are:
First Thessalonians (c. 50 AD)
Galatians (c. 53)
First Corinthians (c. 53-54)
Philippians (c. 55)
Philemon (c. 55)
Second Corinthians (c. 55-56)
Romans (c. 57)

(This leaves out Second Thessalonians (51), Ephesians (62), Colossians (62), 1 Timothy (64), 2 Timothy (64), and Titus (64). Colossians and Second Thessalonians are said to have these scholars “evenly divided” while they oppose the genuineness of the remaining four letters.)

The Pauline canon these scholars have produced is similar to that of Marcion who included the following as genuine:

First Thessalonians
Second Thessalonians
First Corinthians
Second Corinthians

The Marcionite Canon agrees with the modern canon if those books on which “scholars are evenly divided” are included. It also includes Laodiceans which might be Ephesians. If so, all this is saying is that both Marcion and modern “scholars” reject the genuineness of the Pastoral epistles (1 Timothy, 2 Timothy, Titus).
