"[Note: Those who believe infant baptism places a child in the 'covenant of grace' invent an unbiblical nether-realm where the child is neither lost or saved; unless they hold to presumptive or baptismal regeneration.]" (Chapter 1, footnote pp.61-62)
This is just simply wrong. The author assumes the baptistic conceptualization of new covenant membership and then forces it upon a paedobaptistic practice. Surely the author has at least done enough study to realize Presybterians do not see covenantal inclusion the same as Baptists? There is no perceived nether-realm, contrary to quoted allegation above. Until the child has faith, the child is lost. The author's allegation is unsupported in the book.
Apparently Mr. Blackburn is unfamiliar with Westminster Standards. That's truly sad given that he identifies as being reformed. Had he read WLC 58-61, 79, WSC 29,30 or WCF Chapter 7, particularly Section III, he would not have made such an egregious error as above.
"Man by his fall having made himself incapable of life by that covenant, the Lord was pleased to make a second, commonly called the Covenant of Grace: whereby he freely offereth unto sinners life and salvation by Jesus Christ, requiring of them faith in him, that they may be saved; and promising to give unto all those that are ordained unto life his Holy Spirit, to make them willing and able to believe."
