Did the Apostle Paul Really Write All the Letters Attributed to Him?
Some critical scholars suggest that the apostle Paul didn’t really write some of the letters that are now ascribed to him. Ray Van Neste, writing the introduction to 1 Timothy in the ESV Study Bible, has a concise explanation of why the pseudonymity solution is untenable:
It is problematic to argue that these works were written under a false name since the early church clearly excluded from the apostolic canon any works they thought to be pseudonymous. While critics point to the common practice of pseudonymous writing in the ancient world, they usually fail to point out that this practice, though common in the culture, was not common in personal letters, and was categorically rejected by the early church (cf. 2 Thess. 2:2; 3:17; also Muratorian Canon 64-67; Eusebius, Ecclesiastical History 6.12.3). Tertullian (c. A.D. 160-225) wrote that when it was discovered that a church elder had composed a pseudonymous work, The Acts of Paul (which included a purported Pauline letter, 3 Corinthians), the offending elder “was removed from his office” (On Baptism 17). Accepting as Scripture letters that lie about their origin is also a significant ethical problem. Thus, there is a good basis for affirming the straightforward claim of these letters as authentically written by Paul.
In addition to the external evidence (e.g., whether or not pseudonymity [false naming] or pseudepigraphy [false attributing] were accepted practices in the first centuries), Van Neste also points to the internal evidence in 2 Thessalonians where Paul’s comments are relevant. These verses are worth quoting:
2 Thessalonians 2:2: “[Do] not to be quickly shaken in mind or alarmed . . . by . . . a letter seeming to be from us. . . .”
2 Thessalonians 3:17: “I, Paul, write this greeting with my own hand. This is the sign of genuineness in every letter of mine; it is the way I write.”
Given statements like these, it seems logically and morally incompatible to hold to pseudonymity / pseudepigraphy and the ultimate authority of God’s word containing no deception or error.
