I would go further than Francis. I would say that the Institutional Christianity that flourishes today is not only not the same religion practiced by Charlemagne, it is not even the same religion as practiced by Dabney, Machen, Van Til, and O T. Allis. It is not the same Christianity embraced by Bavinck, Vos, Murray, and Gordon H. Clark. Those eight men would have had disagreements between themselves but the disagreements they would have had pale in comparison to the disagreements that exists as between modern “Reformed” “Christianity” now and that which they practiced only a wee bit over 100 years ago.
It is an embarrassment what passes now as Christianity among the Reformed. We have just become our own version of a Pentecostalism that is untethered to any historical reality, relying instead on a more rational and polished “moving of the Spirit.”
I can only say that I rejoice that I am not longer even loosely associated with the Institutional Reformed Church as it is incarnated among the putative “White-Hat” denominations.
Yes, all those men would have quibbles with one another that essentially amount to a matter of degree whereas the moderns differ as a matter of kind. If you read RJR or Bahnsen free from hostile notions, they sound no different than Machen, the other aforementioned men, and certainly the Confession. They were only guilty of being out of step with their times. Now that all the furor has died down, it’s not hard to see this. The ones out of step with the times these days are those who advocate patriarchy and bloodlines.
