Matthew Henry on Romans 1:19–end
In this last part of the chapter the apostle applies what he had said particularly to the Gentile world, in which we may observe,
I. The means and helps they had to come to the knowledge of God. Though they had not such a knowledge of his law as Jacob and Israel had (Psa 147:20), yet among them he left not himself without witness (Act 14:17): For that which may be known, etc., Rom 1:19, Rom 1:20. Observe,
1. What discoveries they had: That which may be known of God is manifest, en autois - among them; that is, there were some even among them that had the knowledge of God, were convinced of the existence of one supreme Numen. The philosophy of Pythagoras, Plato, and the Stoics, discovered a g…

Adam Clarke on Romans 1:24

Between themselves - εν εαυτοις, Of themselves, of their own free accord; none inciting, none impelling.
John Gill on Romans 1:24
Wherefore God also gave them up to uncleanness,.... Not by putting any into them, but by leaving them to the pollution of their nature; by withdrawing his providential restraints from them, and by giving them up to judicial hardness:
through the lusts of their own hearts. The heart of man is the source of all wickedness; the lusts that dwell there are many, and these tend to uncleanness of one sort or another: by it here is meant particularly bodily uncleanness, since it is said they were given up
to dishonour their own bodies between themselves; either alone, or with others; so that as they changed the glory of God, and dishonoured him, he left them to dishonour themselves by doing these…
