WCF: Chapter 23

Of the Civil Magistrate

Civil magistrates may not assume to themselves the administration of the Word and sacraments; or the power of the keys of the kingdom of heaven; yet he has authority, and it is his duty, to take order that unity and peace be preserved in the Church, that the truth of God be kept pure and entire, that all blasphemies and heresies be suppressed, all corruptions and abuses in worship and discipline prevented or reformed, and all the ordinances of God duly settled, administrated, and observed. For the better effecting whereof, he has power to call synods, to be present at them and to provide that whatsoever is transacted in them be according to the mind of God.

The seven great Ecumenical Councils of the early church were all convened by the Emperor. The Westminster Assembly was itself convened by an act of Parliament. This fact by itself does not take away from the great truths articulated by these convocations, but it is indicative of the extent to which church and state were intertwined, a situation which, for the most part, served to foster rather than to mitigate corruption in both realms.

Consequently, I would be in favor of the so-called American revision to this chapter, which has been adopted by the OPC:

“Civil magistrates may not assume to themselves the administration of the Word and sacraments; or the power of the keys of the kingdom of heaven; or, in the least, interfere in matters of faith. Yet, as nursing fathers, it is the duty of civil magistrates to protect the church of our common Lord, without giving the preference to any denomination of Christians above the rest, in such a manner that all ecclesiastical persons whatever shall enjoy the full, free, and unquestioned liberty of discharging every part of their sacred functions, without violence or danger. And, as Jesus Christ hath appointed a regular government and discipline in his church, no law of any commonwealth should interfere with, let, or hinder, the due exercise thereof, among the voluntary members of any denomination of Christians, according to their own profession and belief. It is the duty of civil magistrates to protect the person and good name of all their people, in such an effectual manner as that no person be suffered, either upon pretense of religion or of infidelity, to offer any indignity, violence, abuse, or injury to any other person whatsoever: and to take order, that all religious and ecclesiastical assemblies be held without molestation or disturbance.”
