Brandon Adams discusses some Problems with PRCA Covenant Theology | The Confessing Baptist.
When the condition of any Covenant is performed, it becometh absolute, as if there had never been any annexed to it. Now, Jesus Christ is mentioned as our great High-Priest and Mediatour, and that as having finished the work of Satisfaction, [Heb 8] ver. 1, 2, 6. and the condition contained in the Old, being exactly and compleatly fulfilled by him, it naturally or necessarily must turn into an absolute form as in the New, because upon his performance, nothing more is to be demanded of him, but all must certainly be accomplished unto us.
