2 Thessalonians: An Overview

July 9, 2025 Concordia Publishing House

The city of Thessalonica, named after a sister of Alexander the Great, was 
built within sight of one of the great religious landmarks of ancient Greece. 
Southward, across the Thermaikos Bay, the people could see the distant 
slopes of Mount Olympus, traditional home of the gods in their culture. From the founding of Thessalonica in 315 BC, its inhabitants stood within sight of what they regarded as divine. The community of Jews who settled at Thessalonica were likewise zealous, having persecuted Paul, Silas, and others for teaching that Jesus was the Christ (Acts 17:2–9, 13). Not surprisingly, the 
Christians at Thessalonica demonstrated an intense piety as well as deep 
curiosity about the return of Jesus.

Historical and Cultural Setting

According to reports that reached Paul at Corinth, the Christians of Thessalonica were still standing firm under persecution (2 Th 1:4). But false notions “concerning the coming of our Lord Jesus Christ and our being gathered together to Him” (2:1) had gained currency in the Church. The resultant excited, almost hysterical, expectation (2:2) had led some to 
abandon their regular occupation and to lead an idle and disorderly life in 
dependence upon the charity of the church (3:6–12). 

Debates About the Authorship

Some critical scholars have seriously questioned the authenticity of 2 Thessalonians. The chief arguments against Pauline authorship are listed below, followed by further considerations.

Argument: The second letter largely repeats the first, and this marks it as a 
forgery.
The statement is an exaggeration; about one third of the second letter is 
parallel to the first, and even this does not give the impression of 
mechanical copying, such as might be expected from a forger, for the 
material occurs in a different order from that in the first letter.

Argument: The second letter teaches differently about the end times from 
that of the first. The first letter stresses the fact that the coming of the Lord 
will be like that of a thief in the night, while the second points to certain 
events as signs that must precede and will therefore forewarn of the second
coming.
It should be noted that this same double emphasis is found in Jesus’ own 
teaching concerning His return (Matthew 24:6–8, 36). Paul does not abandon the teaching of the first letter in the second; he simply defines it more sharply 
by the statement that certain events must precede the second coming of 
Jesus. Neither Jesus’ nor Paul’s words provide a means of forecasting the 
end.

The strongest arguments for authenticity are the lack of any motive for a forgery, and the genuinely Pauline tone and character of the second letter. Even some of the scholars who question the authenticity of the letter admit that there is nothing in it that could not have come from the pen of Paul.

Purpose and Recipients

Paul’s second letter is his answer to the congregation’s concerns about the 
return of Christ. It therefore sounds two notes. For those who indulge in 
overheated fantasies about the end times, there are sobering words that 
point to the events that must necessarily precede the coming of the Christ 
in glory (2 Thessalonians 2:1–12). For the despondent and the fearful there is an 
eloquent and reassuring recognition of the new life that God has worked in 
them and a comforting emphasis on the certainty of their election by God 
(1:3–12; 2:13–15). Paul turns the church from both excitement and 
despondency to that sober and responsible activity which is the hallmark of 
the genuinely Christian hope. The hoping church must work for its 
living in sober industriousness and work for its own health as the Church of 
God. 

Summary Content

2 Thessalonians 1:1–2 Paul greets the Christians in Thessalonica as fellow 
members of the Body of Christ (the Church) and blesses them with God’s 
grace and peace.
2 Thessalonians 1:3–12 Paul gives thanks for God’s grace at work among 
the Thessalonians, by which He has created faith and love in them. He 
points to the persecuted Thessalonians as examples for other Christians of 
their time and ours. God’s judgment will be carried out by the Lord Jesus at 
His second coming on the Last Day.
2 Thessalonians 2 Paul warns the Thessalonians not to be misled regarding 
the second coming of Christ, thinking that the day of the Lord has already 
come. He describes those apocalyptic events yet to take place before the 
return of Jesus, specifically the revelation of the man of lawlessness. He also
calls on the Thessalonians to stand firm in the faith the Lord has given 
them. He reminds them that both their calling and comfort have God as the 
source.
2 Thessalonians 3 Paul requests prayer for his missionary work and 
obedience to what he has commanded them. Those who are idle are to be 
avoided and even denied fellowship in order that this might cause them to 
repent, amend their ways, and return to their fellow believers. Paul 
concludes his letter with a prayer for peace and, in his own hand, a blessing
of grace.

Luther on 2 Thessalonians

In the first epistle [5:2], Paul had resolved for the Thessalonians the question of the Last Day, telling them that it would come quickly, as a thief in the night. Now as is likely to happen—that one question always gives rise to another, because of misunderstanding—the Thessalonians understood that the Last Day was already at hand. Thereupon Paul writes this epistle and explains himself.

In chapter 1 he comforts them with the eternal reward of their faith and of their patience amid sufferings of every kind and with the punishment of their persecutors in eternal pain.

In chapter 2 he teaches that before the Last Day, the Roman Empire must first pass away, and Antichrist set himself up as God in Christendom and seduce the unbelieving world with false doctrines and signs—until Christ shall come and destroy him by his glorious coming, first slaying him with spiritual preaching.

In chapter 3 he gives some admonitions, especially that they rebuke the idlers who are not supporting themselves by their own labor. If the idlers will not reform, then the faithful shall avoid them. And this is a stiff rebuke to the clergy of our day. (AE 35:387–88)
