What is the book of 1 Corinthians about in the Bible? Who wrote 1 Corinthians? The apostle Paul wrote 1 Corinthians because the Christians living in Corinth faced a series of problems—including the danger of splintering into factions and even lapsing back into paganism. Other serious problems also needed to be addressed, and Paul's letter provided them with clear advice.
