The tradition from the earliest days of the church has been that Luke, a physician and a close companion of the Apostle Paul, wrote both Luke and Acts (Colossians 4:14; 2 Timothy 4:11).
Ang tradisyon mula sa pinakaunang panahon ng iglesya ay itinuturing na si Lukas, isang manggagamot at malapit na kaibigan ni Apostol Pablo ang sumulat ng Lukas at mga Gawa (Colosas 4:14; 2 Timoteo 4:11).
