From one of John Calvin’s sermons on Deuteronomy, Sermon 33, 5:11, p., 196.:

Behold our Lord Jesus Christ the Lord of glory, abased himself for a time, as says S. Paul Now if there were no more but this, that he being the fountain of life, became a mortal man, and that he having dominion over the angels of heaven, took upon him the shape of a servant, yea even to shed his blood for our redemption, and in the end to suffer the curse that was due unto us (Gal 3:13): were it convenient that notwithstanding all this, he should nowadays in recompense be torn to pieces, by stinking mouths of such as name themselves Christians? For when they swear by his blood, by his death, by his wounds and by whatsoever else: is it not a crucifying of God’s son again as much as in them lies, and as a rending of him in pieces? And are not such folk worthy to be cut of from God’s Church, yea, and even from the world, and to be no more numbered in the array of creatures? Should our Lord Jesus have such reward at our hands, for his abasing and humbling of himself after that manner? (Mich 6:30) God in upbraiding his people says thus: My people, what have I done to you? I have brought you out of Egypt, I have led you up with all gentleness and loving-kindness, I have planted you as it were in my own inheritance, to the intent you should have been a vine that should have brought me forth good fruit, and I have tilled thee and manured thee: and must thou now be bitter to me, and bring forth sower fruit to choke me withal? The same belongs to us at this day. For when the son of God, who is ordained to be judge of the world (John 5:22), shall come at the last day: he may well say to us: how now Sirs? You have borne my name, you have been baptised in remembrance of me and record that I was your redeemer, I have drawn you out of the dungeons where into you were plunged, I delivered you from endless death by suffering most cruel death myself, and for the same cause I became man, and submitted myself even to the curse of GOD my father, that you might be blessed by my grace and by my means: and behold the reward that you have yielded me for all this, is that you have (after a sort) torn me in pieces and made a jestingstock of me, and the death that I suffered for you has been made a mockery among you, the blood which is the washing and cleansing of your souls has been as good as trampled under your feet, and to be short, you have taken occasion to ban and blaspheme me, as though I had been some wretched and cursed creature. When the sovereign judge shall charge us with these things, I pray you will it not be as thundering upon us, to ding us down to the bottom of hell? Yes: and yet are there very few that think upon it.

This great sermon to New Covenant Christians from Deuteronomy reminds me of his commentary on Deuteronomy where he writes:

For, since the fall of Adam had brought disgrace upon all his posterity, God restores those, whom He separates as His own, so that their condition may be better than that of all other nations. At the same time it must be remarked, that this grace of renewal is effaced in many who have afterwards profaned it. Consequently the Church is called God’s work and creation, in two senses, i.e., generally with respect to its outward calling, and specially with respect to spiritual regeneration, as far as regards the elect; for the covenant of grace is common to hypocrites and true believers. On this ground all whom God gathers into His Church, are indiscriminately said to be renewed and regenerated: but the internal renovation belongs to believers only; whom Paul, therefore, calls God’s “workmanship, created unto good works, which God hath prepared, etc.” (Ephesians 2:10.). Calvin, Deut 32:6

It also reminds me of the forty-fourth Q&A of the Westminster Shorter Catachism, which teaches the covenant child to consider Christ his or her redeemer.  Both Westminster and Heidelberg claim this confidence, to a great extent, on the basis of the person’s baptism.  Again, this indicates how far from the Reformed Heritage, our doctrinal standards, and the  Bible the recent Committee report really was.
