Luke, Paul, The Gospel, And Acts

Q

Is there any truth to the possibility that Luke’s gospel and “the so called fifth gospel the book of acts” could have had a lot of Paul’s input? I know that all scripture is inspired by God, but just like Mark’s gospel was really Peter’s account could there be something similar here as well?

A

It’s believed by many that Luke wrote his Gospel and the Book of Acts as a single document, meant to precede Paul’s arrival in Rome. Such an explanatory document was a required part of an appearance before Caesar, to acquaint him with the details of a case he would soon be considering. If so, then it’s likely that Paul would have had considerable input, at least in the second half, which we call the Book of Acts.
