Rome is returning to its pagan roots. Gentiles are returning to paganism. Jews are turning to Christ. Very very end times biblical. Was to be expected, but still kind of unexpected. Which was itself to be expected.
1. Rome isn’t returning to paganism.
2. Gentiles as a whole are not returning to paganism - have you seen the explosion in conversions in India, in China and in Africa?
3. Jews - more than half of them in the years before the destruction of the temple in 70 AD DID turn to Christ. After the destruction of the 2nd temple (as prophesied by Christ in the Olivet discourse, as envisioned by Daniel and as seen in John’s revelations) there were only the Jesus-movement Jews and the Pharisee-jews left as the 2nd temple sects. The Jesus-movement Jews left the term Jews after the Kitos war (where the Zealot Jews massacred gentiles in Cyprus and Cyrene)
2 Thess 2:3: perhaps ‘apostasia’ has a double meaning? A falling away and a sudden departure.
