Acts 5:19

But the angel of the Lord Better, an angel by night opened the prison-doors. As if for a protest against the actions of those who taught that "there was neither angel nor spirit." There is no possibility of explaining St Luke's words into anything but a miraculous deliverance. He gives no word that can be twisted into any other meaning. It was not an earthquake, it was not a friendly human being who interposed to procure the release of the Apostles. The writer readily acknowledges in this very chapter the intervention of Gamaliel and its effect, but he is here speaking of supernatural aid. If it be remarked that the Apostles make no mention of their miraculous deliverance when they are called upon for their defence, it may be answered that they in no case dwell on the miracles either wrought by or for them, except where they have been wrought under the eyes of men and are to be used as signs of the Divine power which was working in and for the Church. To enter on a description of a miracle which had been wrought as this deliverance had been, and to ground their claims to be beard upon circumstances of which the eyes of those to whom they spoke did not bear testimony, is foreign to the whole character of the Apostolic ministry.
