Get ready to be told that St. Peter was never in Rome.
1 Pe 5:13 She who is at Babylon, who is likewise chosen, sends you greetings; and so does my son Mark.
The funny part about this is that the same people do not hesitate to identify Babylon as Rome (specifically the One, Holy, Universal, and Apostolic Church) when performing their eschatological "exegesis."
Wish they'd get it straight.
