“The duty of the civil authority in this matter is hedged about by these three regulations: (1) It must strictly confine itself to its own sphere, and not presume to define heresy; that belongs to the church alone. (2) It must not pass judgment with regard to persons, advantages, and circumstances but with pure regard to the honor of God. (3) It must proceed after quiet, regular examination of the heresy and mature consideration of all the circumstances, and inflict such punishment as will best secure the honor due to the divine majesty and the peace and unity of the church.”
Theodore Beza
Beza, De Hereticis, quoted in Schaff, History, p. 798
Here Beza gives us a classical example of normal two Kingdom theology (as opposed to radical two kingdom virus theology). Notice Beza teaches that the civil realm and the church each have their own respective spheres. Second, in number “2” above the counsel is itself based upon the scriptural teaching that legal rulings must be no respecter of persons. Perhaps natural law teaches that we should consult the Scriptures for insights on these matters? Beza is, as such, using the Scriptures to instruct the Magistrate what his role is. Third, the magistrates ruling is in consideration of both God and church. Clearly Beza would be appalled by radical two kingdom virus theology.
All of this is an example of the quote I lifted from Bavinck yesterday. Here we see that “although nature (civil realm) and grace (church realm) are distinct and may not be confused or mingled, God does link the two.
