This Letter was written from Corinth not long after the
preceding one, and probably in the year 54 A.D. Its occasion was
the reception of tidings from Thessalonica which showed that
there had been a measure of misapprehension of the Apostle's
teaching in regard to the Return of the Lord Jesus, and also that
there was a definitely disorderly section in the Church there,
capable of doing great harm.
Hence Paul writes to correct the error into which his
converts had fallen, and at the same time he uses strong language
as to the treatment to be dealt out to those members of the
Church who were given to idleness and insubordination.
