“Your life amidst the Gentiles must be beyond reproach; decried as malefactors, you must let them see, from your honourable behaviour, what you are; they will praise God for you, when his time comes to have mercy on them. For love of the Lord, then, bow to every kind of human authority; to the king, who enjoys the chief power, and to the magistrates who hold his commission to punish criminals and encourage honest men… Give all men their due; to the brethren, your love; to God, your reverence; to the king, due honour.” (I Peter ii, 12-14, 17)
