The Apostle Paul authored First and Second Corinthians, with help from co-workers.
If you have asked who wrote book of corinthians, you want a clear, proven answer. I have spent years studying the New Testament in classrooms and small groups.
In this guide, I explain the evidence with care. You will see who wrote book of corinthians, why it matters, and how to read these letters with confidence.

What Do We Mean by “Book of Corinthians”?
People often say “book of Corinthians,” but the New Testament has two letters to the church in Corinth. They are First Corinthians and Second Corinthians. Both letters claim Paul as the author. Both letters fit what we know of Paul’s life and mission.
If your search is who wrote book of corinthians, the short form points to both letters together. Scholars treat them as separate but related works. They speak to one church community across a tense and active time. Knowing this helps us frame the question, who wrote book of corinthians, in a precise way.

Evidence from the Text: Claims and Style
First Corinthians starts by naming Paul and Sosthenes. It uses Paul’s typical opening and blessing. In 1 Corinthians 16:21, we read that Paul adds a greeting in his own hand. This was a common sign of authenticity in his letters.
Second Corinthians also opens with Paul’s name, together with Timothy. In 2 Corinthians 10:1, Paul speaks in the first person about his plea to the church. The tone, theology, and focus match Paul’s known style. When we ask who wrote book of corinthians, the internal claims point straight to Paul.

Evidence from Early History and Manuscripts
Early church leaders quote both letters as Paul’s work. Writers from the late first and second centuries cite them often. They include a letter from Rome at the end of the first century that uses 1 Corinthians. Other early teachers in the second century do the same.
Ancient lists of accepted books include both letters as Pauline. Early copies of Paul’s letters also contain them. These facts support the simple answer to who wrote book of corinthians. The church closest to the time believed Paul wrote them, and the manuscripts align with that view.
When and Where Were They Written?
Paul spent about 18 months in Corinth around the early 50s AD. Later, he wrote 1 Corinthians while he was in Ephesus. He says he will stay there until Pentecost. That places the letter around AD 53–55.
2 Corinthians comes soon after. Paul had a painful visit and sent a tearful letter in between. Then he wrote 2 Corinthians from Macedonia around AD 55–56. When people search who wrote book of corinthians, they often also want the date and place. These details help us read the letters in context.

Did Paul Write Alone? Co-authors and Scribes
Ancient authors often used scribes. They also named co-senders who helped shape or deliver the message. In 1 Corinthians, Sosthenes is named. In 2 Corinthians, Timothy is named. The core ideas and voice are Paul’s, but trusted partners stood with him.
A scribe may have helped with wording and form. Paul then signed the closing lines by hand as a mark of truth. So when we ask who wrote book of corinthians, the best answer is Paul as the author, with support from co-workers who helped with delivery and style.
Why Authorship Matters for Interpretation
If Paul wrote these letters, they sit within his larger teaching. The message on unity, holiness, and love in 1 Corinthians fits Paul. So does the deep talk of weakness, power, and comfort in 2 Corinthians. That gives us a strong lens to read, teach, and apply the text.
Knowing who wrote book of corinthians helps you tie themes together. It ties the letters to Acts and to other Pauline texts. It also guides how we read hard parts on gifts, giving, and leadership.
Common Objections and Scholarly Debates
Some scholars suggest 2 Corinthians is a blend of more than one letter. They point to the sharp tone shift in chapters 10–13. Even so, most agree the whole letter is from Paul. The debate is about editing, not authorship.
Others ask if a scribe shaped the style. That is likely true, as with many ancient letters. Yet Paul’s voice and ideas come through. The core claim stands firm. For those still asking who wrote book of corinthians, the wide view among experts is that Paul did.
Practical Takeaways for Readers and Teachers
Here is how this helps your study and teaching today:
- Read 1 Corinthians with church life in view. The letter speaks to division, worship, gifts, and love.
- Read 2 Corinthians with pain and healing in view. The letter shows how leaders suffer and still serve.
- Watch for Paul’s personal notes. He names people, places, plans, and trials.
- Cross-check with Acts. It will anchor the timeline and the travel.
- Keep the main point in sight. The cross shapes church life and leadership.
In my study groups, I have seen people ask who wrote book of corinthians many times. Once they see the evidence, trust grows. Then the hard teachings land with more grace and power.
