cheers, waves, followed by a long, winding ride. the signs of grazie everywhere. the bells of st. peter's basilica ringing out as he arrived at the heliport. then the defender of ancient tradition, boarding a helicopter, rising into a brilliant blue sky, rounding st. peter's and the coliseum. within minutes, the arrival at castel gandolfo. the vacation retreat of popes. crowds greeting him outside his temporary new home. then one last time as pope, benedict stood on a balcony. he spoke. saying i am no longer the pontiff of the catholic church. i am simply a pilgrim, beginning the last leg of his pilgrimage on this earth.
