A few years ago, I think I posted about how the word "Evangelical" has been hijacked from the First Evangelicals. Please note, that observation was not original to me. So now, the word has been so used and misused, we do not know now what that word means.
I have been reading of what has been happening in the Calvinist/Reformed world.
Dr. R. Scott Clark, a Reformed professor of historic theology, wrote a piece here, arguing that the label "Reformed" should be confined to paedo-baptists Calvinists who confess the Continental (Heidelberg Catechism, Belgic Confession, Canons of Dort) and English Calvinist Confessions (Westminster, Savoy, etc).
Famous Reformed Baptists, like apologist Dr. James White of AOMIN.ORG took exception to this.
So in a sense, Dr. Clark's point is that technically the word "Reformed" should be the proper label for infant baptizing Calvinists, and it should not be applied to credo-baptizing ones. Hence, it is not proper for credo-baptists "Calvinists" to call themselves Reformed as another variation of that term, there is no such thing as Reformed Baptist, I think this is what Dr. Clark is saying.
I think Dr. Clark is right, historically Calvinism has a distinct pedigree and paedo-baptism is one of them.
On the other hand, Dr. Clark should know that Calvinists stole many concepts from Lutherans and rehashed them and gave them their own spin. I think this mostly happened in what Lutherans called The Interim.
So, all I can say is, what goes around, comes around, no?
