2:2 The fifth book of the New Testament has been known from ancient times as The Acts of the Apostles; but this title cannot be found in the book itself. One of the earliest manuscripts, the Codex Sinaiticus, gives as the title the simple word Acts, with no mention of the apostles. There is a reason for this. Acts was intended to be more than a brief history of the service rendered by the twelve disciples, much more than the principal events in the lifework of its four leading characters, Peter, James, John, and Paul.
