The only chance for persecution to succeed is to smite hard and swiftly. If you cannot strike, do not threaten. Menacing words only give courage. The rulers betrayed their hesitation when the end of their solemn conclave was but to 'straitly threaten'; and less heroic confessors than Peter and John would have disregarded the prohibition as mere wind. None the less the attitude of these two Galilean fishermen is noble and singular, when their previous cowardice is remembered. This first collision with civil authority gives, as has been already noticed, the main lines on which the relations of the Church to hostile powers have proceeded. I. The heroic refusal of unlawful obedience. We shall probably not do injustice to John if we suppose that Peter was spokesman. If so, the contrast of the tone of his answer with all previously recorded utterances of his is remarkable. Warm-hearted impulsiveness, often wrong-headed and sometimes illogical, had been their mark; but here we have calm, fixed determination, which, as is usually its manner, wastes no words, but in its very brevity impresses the hearers as being immovable. Whence did this man get the power to lay down once for all the foundation principles of the limits of civil obedience, and of the duty of Christian confession? His words take rank with the ever-memorable sayings of thinkers and heroes, from Socrates in his prison telling the Athenians that he loved them, but that he must 'obey God rather than you,' to Luther at Worms with his 'It is neither safe nor right to do anything against conscience. Here I stand; I can do nothing else. God help me! Amen.' Peter's words are the first of a long series. This first instance of persecution is made the occasion for the clear expression of the great principles which are to guide the Church. The answer falls into two parts, in the first of which the limits of obedience to civil authority are laid down in a perfectly general form to which even the Council are expected to assent, and in the second an irresistible compulsion to speak is boldly alleged as driving the two Apostles to a flat refusal to obey. It was a daring stroke to appeal to the Council for an endorsement of the principle in verse 19, but the appeal was unanswerable; for this tribunal had no other ostensible reason for existence than to enforce obedience to the law of God, and to Peter's dilemma only one reply was possible. But it rested on a bold assumption, which was calculated to irritate the court; namely, that there was a blank contradiction between their commands and God's, so that to obey the one was to disobey the other. When that parting of the ways is reached, there remains no doubt as to which road a religious man must take.
