text: Authenticity The majority of New Testament scholars hold 1 Thessalonians to be authentic, although a number of scholars in the mid-19th century contested its authenticity, most notably Clement Schrader and F.C. Baur. 1 Thessalonians matches other accepted Pauline letters, both in style and in content, and its authorship is also affirmed by 2 Thessalonians.
  Integrity
  The authenticity of 1 Thessalonians 2:13–16 has been disputed by some. The following arguments are made against its authenticity based on its content:
  It is perceived to be theologically incompatible with Paul's other epistles: elsewhere Paul attributed Jesus's death to the "rulers of this age" rather than to the Jews, and elsewhere Paul writes that the Jews have not been abandoned by God, for "all Israel will be saved".
  There were no extensive historical persecutions of Christians by Jews in Palestine prior to the first Jewish war.
  The use of the concept of imitation in 1 Thes. 2.14 is singular.
  The aorist ἔφθασε[ν] ("has overtaken") in 1 Thes. 2.16 seems to refer to the destruction of Jerusalem. According to 1 Thes 1:10, the wrath of God is still to come; it is not something that has already shown itself.
  The syntax of these verses deviates from that of the surrounding context.
  Various scholars have since defended the authenticity of these passages.
