“The duplex regnum Christi (twofold kingdom of Christ) as advocated by the Reformed orthodox is not simply — and certainly not principally — a church/state distinction. It is not that that the Reformed orthodox merely distinguished the twofold kingdom as to God’s essential power over the state and Christ’s mediatorial power over His church. Rather, this 17th century distinction is couched in Christological terms, and, more specifically, its basis of distinction is the manner of Christ’s work — that is, whether He is considered to rule essentially as God, or personally and mediately as God-man. For this reason, many of the Reformed orthodox could claim a universality to both the mediatorial and essential kingdom of Christ. As seen in the representative context covered in the following chapters, in this way the Reformed orthodox could consistently argue that the magistrate has a task given to him by Christ (who is mediator and defender of His church); in their mind, however, the magistrates responsibility is limited to the defense, protections, maintenance, and promotion of Christ’s church.
It is also apparent that the doctrine of Christ’s twofold kingdom did not lie dormant following the first generation of Reformers, but even into the 17th century there were continued and ongoing development. An equation of the regnum essentiale (essential reign)/ regnum mediatorium (mediatorial reign) distinction with the early Protestant political/spiritual kingdom distinction is simply not plausible; certainly this is evident were one to only apply the question regarding duration to it. As the following chapters argue, the duplex regnum Christi, as related to the varying political contexts within which it was expressed, experienced ongoing maturation and refinement in both its terms and significance.”

1.) When Beeke writes; “in their mind, however, the magistrates responsibility is limited to the defense, protections, maintenance, and promotion of Christ’s church,” the explanation as to how this is a limitation on the Magistrate is found in the fact that the Magistrate does not handle the keys to the Kingdom and the state can not be a institution responsible for personal conversion. The State remains part of Christ’s Kingdom but it is not responsible for handling the realities of grace (Word & Sacrament).
2.) If Beeke is correct here then R2K with its view on 2k theology is a retrogression to an earlier more immature understanding of 2k theology, though that assessment is definitely an insult to that earlier Reformed 2K covenant theology of Bucer, Calvin and Bullinger, whom would have never countenanced the complete innovations of R2K.
You R2K fanboys out there, read that Beeke quote again… read it carefully because it completely torpedoes the Jesuit Van Drunen’s R2K project.
