I'm sorry, but you're attempting to use an equivalent which isn't there.
Uri Geller was and always has been an entertainer - not a religious leader.
I deliberately chose two examples which showed differing aspects of the same phenomenon. They are both people who have provoked belief in their ability to work supernatural miracles.
Trying to make them out as the same thing is insulting to everyone that has a belief system or religion.
No it isn't. I have a belief system or religion so I can say that with some conviction.
The Pope is a leader figure in millions of people's lives. Uri Geller is an entertainer. Not the same thing at all. If the Pope were to take up flourishing, that would be a man having a hobby. If Uri Geller started flourishing when he wasn't performing or appearing as "Uri Geller - The Psychic", then whatever, that's a guy with a hobby.
Sorry, just to clear this up. Pope John Paul II is not the current Pope. I picked him because he is due to be canonised on April 27 based on confirmation that he has worked miracles. I deliberately didn't pick the current Pope because no such claim has been made about him.
But if Uri Geller went up on stage and bent some spoons, did some dowsing, then broke out a deck of cards at all it would be detrimental to his image. Everything we do is considered consciously and subconsciously by the people who are watching us. We are being judged every second we are appearing as our characters. The things that kind of sort of don't fit are just a little niggle in the back of the mind, but the things that clearly don't fit throw up red flags.
Yes. I've already said I agree with that.
You might be able to pull it off by saying that you are a mystical type character who happens to be interested in cards but in my opinion that kind of divergence will always hinder the overall branding. Displays of skill are not isolated. People understand that if we are displaying a skill when we juggle cards, we will probably be using a similar skill when we do any work involving cards. That's why in the rare instances I use cards I do things that are not skill-based.
Now. If you are being a skill-based performer then by all means - show off. This will help when done well. But if you're trying to make it seem like you're in possession of some supernatural skill or talent, then juggling cards will only lead people think that you're just juggling cards all the time.
I don't think I can have made my point clear. Let me try again.
This debate about whether certain types of performers can flourish with cards fades into insignificance if people have a strong enough character. It's like actors (and we are actors) arguing about whether wearing a certain kind of hat makes you more or less believable. If you are able to inhabit a role fully, it would be possible for you to play around the fringes of that character and explore aspects that may, at first sight, seem counter-intuitive. To give another religious example, Jesus cursed a fig tree and caused it to die because it was out of season and therefore wouldn't provide him with fruit. This could be argued to be out of character for someone who is meant to be all loving and compassionate. Now, rather than Christians seeing this as out of character, many theologians have come up with various interpretations which allow this apparently random and petty act to have some deeper meaning. In other words, when the character of a miracle-worker is absolutely credible, they can do a lot of unusual things without destroying that credibility. If we aspire to appear as genuine miracle-workers, then surely we should take our lead from figures who are regarded as genuine miracle-workers (whether that's John Paul II, Jesus, Mohammed, the saints, Hermes Trismegestus or whoever).
