"The details of the iniquity practiced in his court are too degrading, too horrible, for description. His abandoned wickedness created disgust and loathing, even in many who were forced to share his crimes. They were in constant fear as to what enormities he would suggest next. Yet even such crimes as Nero's did not shake the allegiance of his subjects. He was acknowledged as the absolute ruler of the whole civilized world. More than this, he was made the recipient of divine honors and was worshiped as a god. AA 486.1"
"Professing themselves to be wise, they became fools, And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things."
Both passages address the theme of humanity's descent into wickedness and the worship of corruptible things/people instead of God. The EGW passage describes Nero's court, while Romans 1:22-23 speaks more generally. The connection is valid.
"And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?"
Both passages describe the worship of a ruler/beast, suggesting a parallel between Nero's deification and the events in Revelation.
