The First Letter to the Thessalonians taught us the importance of looking forward to the coming of Christ in Paul’s preaching.
The hope for the Day of Christ was a powerful incentive for preserving the faith of the first Christians. Yet it could lead to an unhealthy nervousness. The Church of Thessalonica was the first example of those minorities and persecuted groups in whom the expectation of the end of the world distorts the normal development of Christian life.
In this letter, written a few months after the first one, Paul tries to reassure the community.
