In fact, the reason why the connexion of thought in this passage seems obscure to us, is probably in part that we have ceased to think of the real fellowship of the naturally unlike—fellowship in all that makes up human life—as a necessary part of the Christian religion. But to St. Paul there was no Christianity without the reality of catholic brotherhood.
2. St. Paul here, as in writing to the Corinthians[[3]], shows himself specially anxious that Gentile Christians should not think they could make light of the Old Testament, or imagine that 'Christ was the end of the law' in any such sense as would make the books of the old covenant superfluous under the new. Their value, he insists, remains permanent. When he is writing to the Corinthians, he finds it in the moral warnings—the warnings of divine judgement upon the chosen people—of which the history is full. In this epistle he is thinking chiefly of the lessons of 'endurance' and divine 'encouragements,' which histories and prophets provide. In his epistle to Timothy[[4]] he thinks of the books as instruments by the use of which the minister or representative of God may become fully educated and equipped for all the purposes of moral supervision and discipline. They can thus educate and equip him, St. Paul teaches, because they were originally written under the influence of a divine inspiration; but it is only when faith has finally attained its true object in Jesus Christ that their real meaning becomes apparent. And this last principle is implied in almost all his use of the Old Testament.
It is a comfort to perceive that none of the elements of permanent value, which St. Paul discerns in the Old Testament, are the least likely to be affected by reasonable criticism of its documents. Its history, critically read, does not become less truly pregnant with moral warnings or lessons of endurance. The encouragements of the prophets are in no respect reduced in force when they are brought into right relation to their own times. The whole library of books is, at least, as capable of educating and equipping the minister of Christ as ever. Their inspiration is still obvious, when it is interpreted candidly in view of all the facts. And still they can only be rightly regarded when they are looked upon as various elements in a progress which has Christ for its goal.
In his use of particular passages in the Old Testament St. Paul here shows himself as free as ever, but with the same fundamental adherence to the true tendency of the Old Testament as a whole. In quoting Ps. lxix. 9 (ver. 3) he is seeing in the afflicted righteous man a type of Christ. This psalm is constantly cited in the New Testament with the same reference[[5]]. It has been supposed[[6]] that St. Paul here adopts a cry addressed to God by the righteous sufferer in the psalm, and represents it as addressed by Christ to his brother man. 'The reproaches aimed at thee, my despised brother, have fallen upon me.' But, as I have tried to show in the analysis above, this supposition is not needed. Christ is represented appealing to God for succour, because He utterly refuses to take the line of self-pleasing; but bears all that men's impatience of God lays upon Him—all their 'wild and weak complaining.' And it is suggestive to remember, with Origen, that it was Christ's 'receiving of sinners and eating with them,' receiving them on the Sabbath as well as other days, that chiefly brought on Him the reproaches of men. This was probably in St. Paul's mind.
In Ps. xviii. 49 (quoted ver. 9) the victorious king declares that he will praise God for his victory 'among the nations.' St. Paul applies this to Christ, whose victory among the nations means their redemption—their becoming His people.
In Deut. xxxii. 43 (ver. 10) 'the nations are invited to congratulate Israel on possessing a God like Jehovah, who will effectually take up His people's cause. Such an invitation addressed to the nations (cf. Isa. xlii. 10-12; Ps. xlvii. 2, lxvii. 1-7, &c.) involves implicitly the prophetic truth that God's dealings with Israel have indirectly an interest and importance for the world at large[[7]].' This is still more plainly implied in Ps. cxvii. 1 (ver. 11).
Isa. xi. 10 (ver. 12) is quoted from the Greek Bible, which is paraphrastic; but the Hebrew also asserts that the messianic king of David's line is to be a 'signal to the nations,' and that they are to 'resort to him' as to an oracle or place of refuge[[8]].
[[1]] We are all 'strong' in some respect, Origen remarks, so that 'ye that are strong bear the infirmities of the weak' comes to be as broad a precept as 'bear ye one another's burdens.'
[[2]] Cf. Gal. iv. 4, 5: 'Christ, born of a woman, born under the law, that he might redeem them which were under the law, that we (Jews and Gentiles) might receive the adoption of sons.'
