I agree. It’s a stunning photo. On the other hand, I doubt God would need the accompanying thunder storm to launch it.
There has been a fair amount of wind and rain in Rome in the last few days (I happen to have been checking the weather there because I was planning a trip to Rome, by coincidence, in the next few weeks).
So I’d say it’s probably real.
When I was at World Youth Day in Madrid two years ago, a horrible wind and rain storm broke out and lightning was slamming down all around us. The Pope sat there, eyes closed, praying, and this was the only thing that calmed down the nearly 1 million people who were there and let us last out the storm.
At the time, it seemed to me that the Devil was striking at the Pope and this is how it seems to me in this photo, too.
So to me, that means that the Pope is doing the right thing by resigning, and something really bad must be brewing - but he has averted it for now and Satan is angry.
Some lightning bolts do not come from the clouds down, they jump from the ground up.
