This requires a subtler explanation.I am merely an inquirer and I do wish to overstep any boundaries.
I (privately) reached out to @MichaelWitcoff some time ago having questions about the second coming of Jesus Christ. In response he sent me a link  to a reading from St. Paisios the Athonite on the topic titled "On Our Times". In listening to the reading I heard that "That’s why Holy Scripture says that even the chosen will be deceived", at 9:51 in the video.
Who are "the chosen" that St. Paisios was referring to if not faithful Christians?
