So far you haven't identified what Scripture defines as the first covenant, and have instead replaced Scripture's definition with one of your own making. In addition, you don't acknowledge Jesus being the Lord of the sabbath in actual practice, as that term conveys His ownership of the sabbath, and His natural right to dispose of the shadow when the reality that it was designed to lead you to came to fruition. This is fully supported in the narratives describing the Gospel.
This translates to an admission that the reality hasn't arrived yet, and there is no new covenant provided in the Blood of Jesus. Also, my complaint concerning your posts is that you're content to pass judgment on Scripture's testimony.
This isn't possible to reconcile with Scripture's testimony explaining the end of the weekly shadow of the sabbath.
You have been sharing an unBiblical faith that cannot be found in Scripture. Your unwillingness to support your belief system in your posts isn't conducive to a discussion that one would hope would further a goal I hold precious - the unity of the faith that was entrusted to us. That faith is presented in the singular.
Ephesians 4
11 And He Himself gave some to be apostles, some prophets, some evangelists, and some pastors and teachers,
12 for the equipping of the saints for the work of ministry, for the edifying of the body of Christ,
13 till we all come to the unity of the faith and of the knowledge of the Son of God, to a perfect man, to the measure of the stature of the fullness of Christ;
14 that we should no longer be children, tossed to and fro and carried about with every wind of doctrine, by the trickery of men, in the cunning craftiness of deceitful plotting,
15 but, speaking the truth in love, may grow up in all things into Him who is the head----Christ----
16 from whom the whole body, joined and knit together by what every joint supplies, according to the effective working by which every part does its share, causes growth of the body for the edifying of itself in love.
Variance from a singular unity is regarded by this author as the "wind of doctrine, by the trickery of men, in the cunning craftiness of deceitful plotting". It is sinful human pride and deceit that has produced denominationalist thought, artificial divisions in the Body of Christ that is an affront to His commandment for us to love one another and edify each other in the singular faith.
Perhaps you didn't know that I came from a background in Messianic Judaism. The terms you use are familiar to me for that reason, as are the concepts. They are wholly unBiblical, the reason you cannot defend them.
