Prof Brown, a confessing Reformed theologian, gives a fair treatmeant of all concerned be it orthodox Calvinist, orthodox Lutheran, and heretic ones of all types. There are a few things he admitted that interest me, one of which is when he says that the first couple of hundred years after the Reformation, the Calvinists produced more heresies than the Lutherans.
The first phase of the Reformation took the universal church out of the center of attention and replaced it with the local congregation; this [Pietism] second wave of Reformation, if we may call it that, redirected attention from the congregation to the individual believer. Christians began to sing "I" rather than "we"
I though this was interesting yet it still goes on today.
