Who ( οἵτινες, with its usual significance, as before) knowing the judgment of God, that they which practise such things are worthy of death, not only do the same, but also have pleasure in them that practise them. In this concluding verse the main point of the whole argument, with which also it began (Romans 1:19), is repeated, viz. that all this sin was in spite of better knowledge—the original knowledge of God revealed, as above set forth, to the human race, and (as is implied further) an inward witness of conscience still remaining, however stifled, even in the most corrupt society. By ἄξιος θανάτου is not meant "deserving of capital punishment;" Divine judgment is evidently implied. There is no need to inquire what conception of future retribution the heathen themselves may be supposed to have had, or to have been capable of entertaining. St. Paul constantly denotes by θάνατος, in a general and comprehensive sense, the penal consequence of unatoned sin due to the Divine δικαιοσύνη (cf. Romans 6:21-23; Romans 8:6, etc.). It is to be observed that in the latter part of this verse the distinction between πράσσειν, meaning habitual practice, and ποιεῖν, is not shown in the Authorized Version. The evidence of the "reprobate mind" is not simply that such things are done occasionally under temptation, but that they are the habits of people's lives. And still more: such habits are not only participated in by those who have knowledge enough to perceive their guilt ( αὐτὰ πποιοῦσιν), but even condoned and approved ( συνευδοκοῦσι τοῖς πράσσουσι); there was no general protest or indignation in society against the prevalent abominations; and those familiar with the writers of the Augustan age must be well aware that this was so. Here we have the final proof of the prevalence of the ἀδόκιμος νοῦς, the climax of the picture of general moral degradation. "Ideo autem sic interpreter, quod video apostolum voluisse hic gravius aliquid et sceleratius ipsa vitioram perpetratione per-stringere. Id quale sit non intelligo, nisi referamus ad istam nequitiae summam, ubi miseri homines contra Dei justitiam, abjecta verecundia, vitiorum patrocinium suscipiunt" (Calvin).
