“I have no one with me but Luke.” —2 Timothy 4:11

St. Luke compiled his Gospel and the Acts of the Apostles not to describe how good things were in the early Church but to address how bad things were becoming after the first generation of Christianity. The Christian community got bogged down with internal problems and was no longer motivated to evangelize. The Church was lukewarm (Rv 3:16). Luke composed his Gospel and Acts of the Apostles to change this.
