LOL, I'm sure there are some priests who doubt the story, there are priests who doubt the True presence of Christ in the Holy Eucharist. Sad to see that in these times one can find a priest who will tell you anything.
And of course there are people who do not believe it, and they do not have too, thats fine with me.
I believe it, millions of others believe it. Pope John Paul II believes it, thats enough for me.
