7 As to which should be preferred no one ought to balance for an instant. It is a high crime indeed to withdraw allegiance from God in order to please men, an act of consummate wickedness to break the laws of Jesus Christ, in order to yield obedience to earthly rulers, or, under pretext of keeping the civil law, to ignore the rights of the Church; "we ought to obey God rather than men."(4) This answer, which of old Peter and the other Apostles were used to give the civil authorities who enjoined unrighteous things, we must, in like circumstances, give always and without hesitation. No better citizen is there, whether in time of peace or war, than the Christian who is mindful of his duty; but such a one should be ready to suffer all things, even death itself, rather than abandon the cause of God or of the Church.
