John Calvin Commentary Romans 1:26

"For this cause God gave them up unto vile passions: for their women changed the natural use into that which is against nature:" — Romans 1:26 (ASV)

God therefore gave them up, etc. After introducing, as it were, an intervening clause, he returns to what he had previously stated concerning the judgment of God: and he brings, as the first example, the dreadful crime of unnatural lust; and from this it appears that they not only abandoned themselves to beastly lusts but also became degraded beyond the beasts, since they reversed the whole order of nature. He then enumerates a long catalogue of vices that had existed in all ages and, at that time, prevailed everywhere without any restraint.

It is beside the point to say that not everyone was burdened with such a great mass of vices; for in indicting the common wickedness of humanity, it is sufficient proof if all, without exception, are compelled to acknowledge some faults. Therefore, we must consider that Paul here records those abominations that had been common in all ages and were, at that time, especially prevalent everywhere; for it is astonishing how common then was that filthiness which even brute beasts abhor; and some of these vices were even popular.

And he recites a catalogue of vices, in some of which the whole human race was involved; for though all were not murderers, or thieves, or adulterers, yet there was no one who was not found polluted by some vice or another. He calls those disgraceful passions, which are shameful even in human estimation and result in the dishonoring of God.
