“As Sodom and Gomorrha, and the neighbouring cities, in like manner, having given themselves to fornication, and going after other flesh, were made an example, suffering the punishment of eternal fire.”
“Secondly, if, according to the Scripture, they who shall be "apprehended" by the faith in (the state of) Gentile marriage are not defiled (thereby) for this reason, that, together with themselves, others also are sanctified: without doubt, they who have been sanctified before marriage, if they commingle themselves with "strange flesh," cannot sanctify that (flesh) in (union with) which they were not "apprehended.”
“As Sodom and Gomorrah, and the neighboring cities, etc. Because He had given an example of condemnation in those who solely deny the Sovereign and our Lord Jesus Christ, by recalling the ruin of the murmuring and unfaithful people in the desert, or those rising against the author of the wicked angels, so He gives an example of the punishment of those who turn the grace of our Lord Jesus Christ into licentiousness, recalling the burning of Sodom.”
“As an example that unquenchable fire will encompass them, the inhabitants of Sodom are also brought forward. "Other flesh" refers to the male nature, as not serving such intercourse as to give birth. For such intercourse the female flesh is capable, according to the saying of the forefather: "bone of my bones and flesh of my flesh" (Gen. 2:23), while the flesh of the male, as I said, is alien to such intercourse. And even female flesh, according to the laws, belongs as one's own and proper flesh to one alone, but that which mingles with many is other and alien flesh, and in defilement falls little short of the male.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
