It is not the manner of the Romans to deliver any man to die - Χαριζεσθαι τινα ανθρωπον, To Make a Present of any man; gratuitously to give up the life of any man, through favor or caprice. Here is a reference to the subject discussed on Acts 25:11.

Before that he which is accused have the accusers face to face, etc. - For this righteous procedure the Roman laws were celebrated over the civilized world. Appian, in his Hist. Roman., says: ου πατριον σφισιν ακριτους καταδικαζεσθαι. It is not their custom to condemn men before they have been heard. And Philo De Praesid. Rom., says: τοτε γαρ κοινους ἑαυτους παρεχοντες δικαϚας εξ ισου, και των κατηγορων και απολογουμενων ακουομενοι, μηδενος ακριτου προκαταγινωσκειν αξιουντες, εβραβευον ουτε προς εχθραν, ουτε προς χαριν, αλλα προς την φυσιν της αληθειας, τα δοξαντα ειναι δικαια. "For then, by giving sentence in common, and hearing impartially both plaintiff and defendant, not thinking it right to condemn any person unheard, they decided as appeared to them to be just; without either enmity or favor, but according to the merits of the case." See Bp. Pearce. England can boast such laws, not only in her statute books, but in constant operation in all her courts of justice. Even the king himself, were he so inclined, could not imprison nor punish a man without the regular procedure of the law; and twelve honest men, before whom the evidence has been adduced, the case argued, and the law laid down and explained, are ultimately to judge whether the man be guilty or not guilty. Here, in this favored country, are no arbitrary imprisonments - no Bastiles - no lettres de cachet. Lex facit Regem: the law makes the king, says Bracton, and the king is the grand executor and guardian of the laws - laws, in the eyes of which the character, property, and life of every subject are sacred.

Whether it is Lawful for the Accused to Escape Judgment by Appealing?
Objection 1: It would seem unlawful for the accused to escape judgment by appealing. The Apostle says (Rom. 13:1): "Let every soul be subject to the higher powers." Now the accused by appealing refuses to be subject to a higher power, viz. the judge. Therefore he commits a sin. Objection 2: Further, ordinary authority is more binding than that which we choose for ourselves. Now according to the Decretals (II, qu. vi, cap. A judicibus) it is unlawful to appeal from the judges chosen by common consent. …

From Antioch to the Destruction of Jerusalem.
Acts 13-28 and all the rest of the New Testament except the epistles of John and Revelation. The Changed Situation. We have now come to a turning point in the whole situation. The center of work has shifted from Jerusalem to Antioch, the capital of the Greek province of Syria, the residence of the Roman governor of the province. We change from the study of the struggles of Christianity in the Jewish world to those it made among heathen people. We no longer study many and various persons and their …

One Argument which Has Been Much Relied Upon but not More than Its Just Weight...
One argument which has been much relied upon (but not more than its just weight deserves) is the conformity of the facts occasionally mentioned or referred to in Scripture with the state of things in those times, as represented by foreign and independent accounts; which conformity proves, that the writers of the New Testament possessed a species of local knowledge which could belong only to an inhabitant of that country and to one living in that age. This argument, if well made out by examples, is …
