Here is a summary of Owen’s 17 differences between the Old Covenant and New Covenant, taken from his Hebrews 8:6 commentary. Sometimes I have retained his wording, but other times I have formatted them differently. You can find an online version of the commentary at Study Light.
There is also a great collapsible outline made by Brandon Adams at http://www.1689federalism.com/owen/demo/owen.html.
Difference 1
- These two covenants differ in the circumstance of time as to their promulgation, declaration, and establishment. The first covenant was made at the time that God brought the children of Israel out of Egypt, and took its date from the third month after their coming up from thence, Ex 19:24. From the time of what is reported in the latter place, wherein the people give their actual consent unto the terms of it, it began its formal obligation as a covenant. The new covenant was declared and made known “in the latter days,” Heb. 1:1-2; “in the dispensation of the fullness of times,” Eph. 1:10. And it took date, as a covenant formally obliging the whole church, from the death, resurrection, ascension of Christ, and sending of the Holy Ghost.
Difference 2
- They differ in the circumstance of place as to their promulgation; which the Scripture also taketh notice of. The first was declared on mount Sinai; the manner whereof, and the station of the people in receiving the law Ex 19:18. The other was declared on mount Zion, and the law of it went forth from Jerusalem, Isa 2:3. This difference, with many remarkable instances from it, our apostle insists on, Gal 4:24-26. And it “answereth,” or “is placed in the same series, rank, and order with Jerusalem,” namely, in the opposition of the two covenants. For as the new covenant, the covenant of promise, giving freedom and liberty, was given at Jerusalem, in the death and resurrection of Christ, with the preaching of the gospel which ensued thereon; so the old covenant, that brought the people into bondage, was given at mount Sinai in Arabia.
Difference 3
They differ in the manner of their promulgation and establishment.
- Of the Old Covenant:
- The dread and terror of the outward appearance on mount Sinai, which filled all the people, yea, Moses himself, with fear and trembling, Matt. 12:18-21; Ex. 19:16; 20:18-19. Together herewith was a spirit of fear and bondage administered unto all the people, so as that they chose to keep at a distance, and not draw nigh unto God, Deut. 5:23-27.
- That it was given by the ministry and “disposition of angels,” Acts 7:53; Gal. 3:19. Hence the people were in a sense “put in subjection unto angels,” and they had an authoritative ministry in that covenant.
- Of the New Covenant:
- The Son of God in his own person did declare it. This he “spake from heaven,” as the apostle observes; in opposition unto the giving of the law “on the earth,” Heb. 12:25. Yet did he speak on the earth also; the mystery whereof himself declare...
