The photo, and just what it was that was being kissed has been gone over and "answered" on this forum many times in the past.
It certainly was a Koran according to a Catholic from Iraq who had traveled with others, including the Muslim who presented the "gift" to that pope. Though to this day there may be [Roman] Catholics (aka -- papists?) who may attempt to deny the truth -- that the book, given as a gift to that pope, was indeed kissed by that man.
John Paul II kissed nearly everything. He would kiss the ground upon exiting an airplane.
And that not coming from the school of thought, "any landing one can walk away from is a 'good' landing".
Thanks, but I responded to that already in a recent post!
