I have personally seen Newt at the Shrine for at least the past four to five years (not receiving communion) , so any talk of a sudden conversion is likely unfounded.
I can verify your statement having turned my head when walking through the cafeteria downstairs some six or seven years ago recognizing a voice and then seeing Newt holding court with a handful of folks. Later, sitting in my car getting ready to leave, Newt got in the car right in front of me...a white Cadillac Escalade.
