The official Federal Vision joint statement says this on page 6:
“We deny that law and gospel should be considered as a hermeneutics, or treated as such…. The fundamental division [between law and gospel] is not in the text, but rather in the human heart.”
Ursinus: “The doctrine of the church consists of two parts: the Law, and the Gospel, in which we have comprehended the sum and substance of the sacred Scriptures.” “The duties of the ministers of the church include in general, 1) A faithful and correct exposition of the true and uncorrupted doctrine of the law and gospel, so that the church may be able to understand it” (Zacharius Ursinus, Commentary on the Heidelberg Catechism trans. G. W. Williard [Phillipsburg: P&R, n.d], 2, 572).
I trust extended comment is not needed, yet I want to be sure to point out that the FV says the law/gospel division is “in the human heart” while Ursinus says it is in “the Scriptures.”
