So, I am not uncomfortable at all with the term "republication." I am disturbed by the idea that God ever intended to convey that he might grant, or hypothetically proposed to grant, in the post-fall estate any secular blessings strictly on the basis of a covenant arrangement. That the Mosaic covenant-conditions allowed for the blinded to make this kind of assumption was certainly intended by Jehovah. But that he meant such republication to be reckoned by the faithful as according to their WORK goes against the whole grain of biblical religion.
Israel's (especially Judah's) failure and subsequent judgment according to these stipulations was on account of their moral degradation, and not because they allowed their external observances to lapse.
If I am understanding you correctly Bruce I still have some questions. Were there death penalties for violations of moral law in the OC? Was there any promise of blessedness in the OC for obedience?
I do believe the law was republished to show the sinfulness of sin and our inability to keep it. Romans 7 is proof of that, is it not?
Either way I still believe the Covenant of Works is republished in the decalogue. Do this and live is implied in the 5th commandment. Disrespecting or Cursing them had a severe punishment of death. So at some level there is a Do This And Live mentality. Violate this and thou shalt die is also in the law.
Anyways, I need to reread your post a few times to get the gist of it.
(Exo 20:12) Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee.
(Eph 6:1) Children, obey your parents in the Lord: for this is right.
(Eph 6:2) Honour thy father and mother; (which is the first commandment with promise,)
(Eph 6:3) That it may be well with thee, and thou mayest live long on the earth.
(Exo 21:15) And he that smiteth his father, or his mother, shall be surely put to death.
(Exo 21:16) And he that stealeth a man, and selleth him, or if he be found in his hand, he shall surely be put to death.
(Exo 21:17) And he that curseth his father, or his mother, shall surely be put to death.
Do you see why I am having problems here with what I hear you saying? There is a promised blessing / cursing motif' here in this covenant. It is based upon some level of obedience.
There are conditions of a sort in the New Covenant also
(a) E.g. If you are outwardly in the New Covenant by baptism and the Lord's Supper you will still end up in Hell, if you do not believe and repent. Also your exposure to God's Word and your privilege of growing up and/or being among God's New Covenant people will mean that Hell will be a greater punishment for you.
(b) E.g. Those in God's New Covenant can be chastised even to death. See e.g. I Corinthians 11. Presumably true believers can be chastised even unto death, because the Apostle says that some who despised the Lord's Supper "slept" in death.
(c) The New Covenant has conditions about what is acceptable behaviour for the professing Christian before he/she is excommunicated from the Church and Covenant until he/she shows signs of repentance.
(d) God in Christ can remove the presence of His Spirit from a congregation that strays and then even permit that the congregation ceases to exist in His Providence see e.g. Revelation's Letters to the Churches.
(e) A congregation may not find success in evangelism if it is not following Christ closely (?)
The idea that the New Covenant is unconditional is not correct. It is unconditional in the sense that if you as an individual truly believe in Christ you will be saved and go to Heaven, but in other ways it is not.
Re the Old Covenant conditions, it may be an obvious point but it should also be said that if someone who truly believed, committed a flagrant, gross and presumptious breach of the 10C and lost his right to access to a sacrifice for that sin-crime (remember sacrifices were only offered for "sins done in ignorance" as defined by the Torah) and was duly convicted and executed by stoning or some other way, the soul of that believer who had been excommunicated by death and typologically suffered God's wrath for his/her sin, went straight into glory.
So in that ultimate sense of the security of those who truly believe the Old Covenant was also unconditional, just like the New. In other lesser ways it was conditional.
but into the second only the high priest goes, and he but once a year, and not without taking blood, which he offers for himself and for the unintentional sins of the people (Hebrews 9:7, ESV).
Both Old and New Covenants are unconditional in an ultimate sense regarding personal salvation, but both Old and New Covenants are conditional - in different ways to each other - as respects other matters.
There are plenty other ways in which both the Old and New Covenants are conditional which I haven't mentioned and maybe haven't thought of.
E.g. the Covenant promises to children of adults in the covenant must be in some sense conditional, otherwise every child of a professing Christian or, at least, professing Christian believer would believe.
