The Apostle Paul wrote more of the New Testament than Luke. Specifically, Paul is attributed with 13 letters (or epistles), while Luke authored just two books: the Gospel of Luke and the Book of Acts.
Paul’s writings cover a range of topics, including theology, ethics, and church organization, and they played a pivotal role in the early Christian church. His letters to various congregations were meant to address specific issues, provide guidance, and offer encouragement. In contrast, Luke’s contributions, while significant, are limited to these two volumes. The Gospel of Luke provides a detailed account of the life and ministry of Jesus, while the Book of Acts chronicles the early church’s history and the spread of the Gospel after Jesus’ ascension.
In terms of sheer volume, Paul’s letters amount to more than half of the New Testament by word count, while Luke’s work, though vital, is confined to the aforementioned texts. Therefore, it is accurate to say that Paul authored more of the New Testament than Luke did.
