Romans 2

16. In the day, &c.--Here the unfinished statement of Romans 2:12 is resumed and closed.
shall judge the secrets of men--here specially referring to the unfathomed depths of hypocrisy in the self-righteous whom the apostle had to deal with. (See Ecclesiastes 12:14 , 1 Corinthians 4:5 ).
according to my gospel--to my teaching as a preacher of the Gospel.

17-24. Behold--"But if" is, beyond doubt, the true reading here. (It differs but in a single letter from the received reading, and the sense is the same).

18. approvest the things that are excellent--"triest the things that differ" (Margin). Both senses are good, and indeed the former is but the result of the latter action.

20. hast the form of knowledge and of the truth in the law--not being left, as the heathen are, to vague conjecture on divine things, but favored with definite and precise information from heaven.

22. thou that abhorrest idols--as the Jews did ever after their captivity, though bent on them before.
dost thou commit sacrilege?--not, as some excellent interpreters, "dost thou rob idol temples?" but more generally, as we take it, "dost thou profane holy things?" (as in Matthew 21:12 Matthew 21:13 , and in other ways).

24. as it is written--(See Isaiah 52:5 , Marginal reference).

25-29. For circumcision--that is, One's being within the covenant of which circumcision was the outward sign and seal.
verily profiteth, if thou keep the law--if the inward reality correspond to the outward sign.
but if, &c.--that is, "Otherwise, thou art no better than the uncircumcised heathen."

26. Therefore if the uncircumcision keep the . . . law, &c.--Two mistaken interpretations, we think, are given of these words: First, that the case here supposed is an impossible one, and put merely for illustration [HALDANE, CHALMERS, HODGE]; second that it is the case of the heathen who may and do please God when they act, as has been and is done, up to the light of nature [GROTIUS, OLSHAUSEN, &c.]. The first interpretation is, in our judgment, unnatural; the second, opposed to the apostle's own teaching. But the case here put is, we think, such as that of Cornelius ( Acts 10:1-48 ), who, though outside the external pale of God's covenant, yet having come to the knowledge of the truths contained in it, do manifest the grace of the covenant without the seal of it, and exemplify the character and walk of Abraham's children, though not called by the name of Abraham. Thus, this is but another way of announcing that God was about to show the insufficiency of the mere badge of the Abrahamic covenant, by calling from among the Gentiles a seed of Abraham that had never received the seal of circumcision and this interpretation is confirmed by all that follows.

28. he is not a Jew which is one outwardly, &c.--In other words, the name of "Jew" and the rite of "circumcision" were designed but as outward symbols of a separation from the irreligious and ungodly world unto holy devotedness in heart and life to the God of salvation. Where this is realized, the signs are full of significance; but where it is not, they are worse than useless.

Note, (1) It is a sad mark of depravity when all that is designed and fitted to melt only hardens the heart ( Romans 2:4 , and compare 2 Peter 3:9 , Ecclesiastes 8:11 ). (2) Amidst all the inequalities of religious opportunity measured out to men, and the mysterious bearing of this upon their character and destiny for eternity, the same great principles of judgment, in a form suited to their respective discipline, will be applied to all, and perfect equity will be seen to reign throughout every stage of the divine administration ( Romans 2:11-16 ). (3) "The law written on the heart" ( Romans 2:14 Romans 2:15 )--or the Ethics of Natural Theology--may be said to be the one deep foundation on which all revealed religion reposes; and where we have what we may call its other foundation--the Physics and Metaphysics of Natural Theology. The testimony of these two passages is to the theologian invaluable, while in the breast of every teachable Christian it wakens such deep echoes as are inexpressibly solemn and precious. (4) High religious professions are a fearful aggravation of the inconsistencies of such as make them ( Romans 2:17-24 ). See 2 Samuel 12:14 . (5) As no external privileges, or badge of discipleship, will shield the unholy from the wrath of God, so neither will the want of them shut out from the kingdom of heaven such as have experienced without them that change of heart which the seals of God's covenant were designed to mark. In the sight of the great Searcher of hearts, the Judge of quick and dead, the renovation of the character in heart and life is all in all. In view of this, have not all baptized, sacramented disciples of the Lord Jesus, who "profess that they know God, but in works deny Him," need to tremble--who, under the guise of friends, are "the enemies of the cross of Christ?"
