Many believe it was written around 51–52 AD, shortly after the First Epistle. Others think a date of around 80–115 AD is more likely. These are scholars who say that the second letter is quite different from the First Epistle to the Thessalonians and may have been written by someone else. Those who believe Paul wrote "Second Thessalonians" also note how Paul signed it himself: "I, Paul, write this greeting with my own hand, which is how I write in every letter.".
