The books of 1 Corinthians and 2 Corinthians in the Bible are traditionally understood to have been written by the apostle Paul, addressed to the Christian church in the city of Corinth.

Most modern scholars, across a wide range of Christian traditions and academic backgrounds, agree that both letters are genuinely Pauline, meaning they truly come from Paul rather than being written later in his name. In the text of each letter, Paul identifies himself as the author in the opening greeting, which is one of the key reasons for this consensus.

Some researchers discuss whether our current “2 Corinthians” might combine parts of more than one letter Paul wrote to the Corinthians, since the New Testament itself hints at additional correspondence now lost. However, even in those discussions, the material that makes up 1 and 2 Corinthians is still attributed to Paul as its original writer, whether dictated to a scribe or written in his own hand.
