"The Acts of the Apostles seem, indeed, to express bare history and to narrate the infancy of the newborn church, but if we recognise that the author of Acts is Luke, a doctor, 'whose praise is in the Gospel' (2 Cor. 8.18) we perceive that all his words are equally medicines for the sick soul." - Jerome, Epist. 53.9 as quoted in C.K. Barrett, Acts 1.34.
