II Timothy 4:11; Philemon 1:24
Luke 1:2 – Not a personal eyewitness of Jesus
All early records unanimously name Luke as the writer of Luke and Acts.
Three indicators that Luke wrote both Luke and Acts
To whom addressed?
“… to write out for you in consecutive order, most excellent Theophilus” (Luke 1:3)
“The first account I composed, Theophilus …” (Acts 1:1)
Continuity of action
“He parted from them and was carried up into heaven” (Luke 24:51)
“The first account … until the day when He was taken up” (Acts 1:2)
Continuity of promise
“I am sending forth the promise of my Father upon you; but you are to stay in the city …” (Luke 24:49)
“He commanded them not to leave Jerusalem, but to wait for what the Father had promised” (Acts 1:4)
Nothing is known about him. The name means “friend of God.” Theophilus could be a specific person or a general term for any friend of God.Acts covers about 30 years of the earliest history of the church.

Bible contradiction? Acts 1:8
http://apologeticspress.org/AllegedDiscrepancies.aspxSelecting a new apostle – Acts 1:15-26
The new apostle had to be an eyewitness of Jesus.The word “witness” is used many times in the New Testament, but people use it in a different way today. The apostles were witnesses of things they had seen with their own eyes.
The apostles were the prime witnesses.
Luke 24:46-48; John 15:26-27; 19:35; 20:30-31; 21:24; Acts 1:8, 22; 2:32, 40; 3:15; 4:33; 5:32; 8:25; 10:39-42; 13:3The apostles could tell people what they had seen with their own eyes.
I Peter 5:1; II Peter 1:16-19; I John 1:1-4; 4:14; Revelation 1:1-2Matthias qualified as an apostle because he was an eyewitness. Acts 1:21-22
Paul became a witness because Jesus appeared to him.
Acts 9:3-5; 18:5; 20:21, 24; 22:14-15; 23:11; 26:16, 22; 28:23; I Corinthians 15:15
