Paul, Silvanus, and Timothy, to the assembly of the Thessalonians in God our Father, and the Lord Jesus Christ:
    Apparently a "forged" letter claiming to be from Paul was circulating among them and caused confusion (2 Thessalonians 2:2-3). Some were speculating that the time of Christ’s return was imminent and were connecting it with the day of God’s judgment upon their enemies (the coming fall of Jerusalem in AD 70).
