Theophilus
Acts 1:1
1:1 Theophilus. The “former treatise” is clearly the gospel of Luke, both books being addressed to “Theophilus” (a name meaning “lover of God”). If Theophilus is not a generic name for anyone who is a lover of God, then the reference is evidently to a Roman official (as indicated by the adjective “most excellent” in Luke 1:3) in whom Luke had special interest, either seeking to lead him to Christ or to build him up in his newfound Christian faith.
