2 Thessalonians 2 is as apocalyptic as Paul gets in his letters. While there are other hints of an apocalyptic worldview in Paul, 2 Thess 2 develops a view of the future which is in step with Second Temple Judaism’s view that God would allows a general persecution at the end of the age.
For example in 1 Enoch 48-50, the “Son of man” will become a “staff for the righteous ones,” people may lean on him and not fall; he will be the hope of the sick and all who dwell on the earth will worship him (48:4-5, cf. 62:6, 9, 63, 90:37; Ps. 72:9, 11; Phil. 2:10.) He will be the light of the Gentiles (Isa. 42:6, 49:6, cf. Luke 2:32). The righteous will be saved by his name (48:7). All of the powerful will be humiliated “in those days” as we are told they will be delivered into the hand of the Chosen One like grass to the fire or lead to the water. The image of grass being taken to a fire at the time of the harvest is used by Jesus in several parables (for example, the wheat and the tares, Matthew 13:24-30, 36-43).
In 1 Enoch 50 the prophet describes a renewal of the righteous from their time of weariness. This includes a judgment in which the sinners receive evil and the righteous receive good. The righteous are to be saved through the “name of the Lord of Spirits” who will lead people to repentance. This chapter stresses the justice of the judgment of the Lord of Spirits – “oppression cannot escape him.” Those who are under his judgment no longer receive mercy (verse 5).
Paul’s apocalyptic description of the activities of the Anti-Christ and his coming judgment resonate with 1 Enoch. In 2 Thess 2 as a parody of the “real Christ.” The man of sin has a “coming” is παρουσία, the word that is most regularly associated with the return of Christ. Just as Christ has a παρουσία, so to does his doppleganger, the Anti-Christ. The Anti-Christ will do “counterfeit miracles, signs and wonders.” The “miracles, signs and wonders” are also a part of this the Satanic parody since these are the very words associated with the ministry of Jesus and his presentation as the Messiah in Acts 2:22 and his representatives (Cf., Heb 2:3-4).
These “miracles, signs and wonders” are modified by ψευδος, a lie. The word is used here and in verse 11, underscoring the false-ness of the activities of the Anti-Christ. The signs will likely be much like the miracles of Christ, although powered by Satan. This is parallel to Revelation 13:1-4, 13-15, the most detailed discussion of the activities of these end-time players. While the true Messiah did great signs and miracles, he was rejected by his people. The Anti-Christ will demonstrate the same sorts of power, but he will be accepted by the people and worshiped as a god.
The goal of these signs is to deceive people. While the miracles may appear to be good and positive things, things that help people. Those that are deceived are described as perishing since they have rejected the love of truth. The word for “perishing” here is the same as the description of the Anti-Christ in verse 3, “son of perdition.” Those that are perishing will be lead to believe the ultimate “one who is perishing.”
When Jesus return in 2 Thess 2:8, he destroys the power of the man of sin with the power of his word, not unlike the description of the beginning of the messianic age in Isaiah 11:4. The timing of the judgment of the Anti-Christ is at the “splendor of his coming.” This combines παρουσία and the word ἐπιφάνεια, a word that also means something like “appearance,” and is applied to the return of Christ a number of times in the New Testament. The combination of the words was used to describe the arrival of the Emperor from the time of Caligula on, implying the presence of a divine being as well as all of the pomp and ceremony associated with the Emperor.
Paul therefore resonates with the Jewish apocalyptic traditions common in the Second Temple period, at least in this earliest of his letters.
