What does Luke 1:3 mean?
Luke notices others are recording facts about Jesus' earthly ministry. Those accounts include eyewitness records and other points of history (Luke 1:1–2). Critics of faith often forget that Christian belief spread before the writing of letters from men like James (James 1:1), Paul (1 Corinthians 1:1–2) and Peter (1 Peter 1:1–2). Many of those messages were themselves in circulation prior to the Gospels. Christian faith was driven by experience and testimony, not by interesting storytellers.Luke is confident he can make a valuable contribution to these efforts. He was a travelling companion of the apostle Paul (Acts 16:10), perhaps serving as Paul's personal doctor (Colossians 4:14). His writing is based on careful research and investigation. That likely includes direct, first-hand accounts told to Luke by the primary figures of these stories. The intent of this historical record is to inspire confidence (Luke 1:4). Luke's approach is deliberate, orderly, and factual. This emphasis on rational, reasonable belief is common theme in early Christianity (Acts 17:11; 1 John 4:1).
Nothing is known of Theophilus, mentioned both here and in the introduction to the book of Acts (Acts 1:1–3). His name literally means "lover of God." For that reason, some have suggested "Theophilus" is a category—i.e., "you who love God"—rather than a proper name. That the honorable title "most excellent" is attached suggests a royal or government role, however.
