Matthew 20:26

But it shall not be so among you
This is not to be extended to Christian nations, as if there were to be no order of magistracy subsisting in them; but that all must be on a level, and no distinction of princes and subjects, of governors and governed; nor to Christian churches, as if there was no ecclesiastical authority to be used, or any church government and power to be exercised; none to rule, whom others are to obey and submit themselves to; but is to be restrained to the apostles as such, among whom there was an entire equality; being all apostles of Christ, being equally qualified and sent, and put into the selfsame office by him: the same holds good of all pastors of churches, who have no superintendency and pre-eminence over one another, or can, or ought to exercise any lordly power and authority, one, or more, over the rest; being equally invested with the same office power, one as another: for otherwise Christ's kingdom would appear like the nations of the world, and to be of a worldly nature; whereas it is spiritual, and does not lie in worldly pomp and grandeur, and in external superiority and pre-eminence of one another; but in the spiritual administration of the word and ordinances; which every pastor of a church has an equal right to exercise, and obedience to them lies in a submission to these things:

but whosoever will be great among you, let him be,
or, as in Mark, shall be your minister:
whoever would be reckoned a great man in the kingdom of Christ, or under the Gospel dispensation, must be a minister to others if he is desirous of being truly great in the esteem of God, and of men, he must do great service for Christ, and to the souls of men; and seek to bring great glory to God, by faithfully ministering the word and ordinances, and by denying himself worldly honour and glory, and by serving others, through much reproach, difficulty, and opposition.
