Romans 1:26-27 [edit]
Saint Paul writing his Epistles
In the Epistle to the Romans 1:26-27 (English Majority Text Version, EMTV), Paul writes
" For this reason [idolatry] God gave them up to passions of dishonor; for even their females exchanged the natural use for that which is contrary to nature, and likewise also the males, having left the natural use of the female, were inflamed by their lust for one another, males with males, committing what is shameful, and receiving in themselves the recompense which was fitting for their error.
As with a lot of this, it comes down to who is doing the interpreting and what words are being translated into what, so of course its entirely debateable. But I was raised Southern Baptist, so I can explicitly remember shit like that passage being quoted as justification for being anti homosexuality.
The book of Revelations could definitely be speaking of Nero's reign, but it was pretty much written before the fall of the Western Roman empire by several hundred years (fall of Rome is like 455CE is when it was sacked, 476CE the last Western Roman emperor is deposed, book of Revelation was compiled between 70 and 90 CE, scholars believe) and close to 1000 before the fall of the Eastern Empire.
And yeah, the placement of books is entirely up to interpretation, so Revelations very well could go elsewhere, but it seems to make the most sense where it is in the context of a religious dogma. Every religion needs its Ragnarok.
