Thanks for posting that Pilgrim! I read it and feel I need to do more reading before I come to any definite conclusions.
I tend to disagree with him when he says: "Whether or not the administration is designated covenant, the uniqueness and singularity must be recognized. It should never be confused with what Scripture calls the old covenant or first covenant (cf. Jer. 31:31-34; 2 Cor. 3:14; Heb. 8:7, 13). The first or old covenant is the Sinaitic. And not only must this confusion in denotation be avoided, but also any attempt to interpret the Mosaic covenant in terms of the Adamic institution. The latter could apply only to the state of innocence, and to Adam alone as representative head. The view that in the Mosaic covenant there was a repetition of the so-called covenant of works, current among covenant theologians, is a grave misconception and involves an erroneous construction of the Mosaic covenant, as well as fails to assess the uniqueness of the Adamic administration."
and perhaps when he said: "In Adam’s expulsion we should find, therefore, a signal manifestation of preventive grace, not only the grace of preventing an aggravation of Adam’s sin, as noted already, but of preventing confirmation in sin, misery, and death, of preventing a sin that would have sealed his doom. God shielded Adam from the sin that would have put him outside the sphere of redemption."
and definitely when he said: "We are liable to regard the Adamic administration as abstract, unrelated to our situation and practical interest, and so far removed from us that it has little or no relevance. If we are inclined to think so, it is because we do not have a biblically conditioned way of thinking. The Adamic institution is intensely relevant if our thought is regulated by the biblical revelation."
I see no reason to stop calling the covenant of works the covenant of works. His reasons were for calling it The Adamic Administration were not adequate.
