And that is the difference between being an Internet armchair expert and someone with real experience.
It's the difference between getting "the shot" and getting "a shot." If all you want to deliver is "a shot," then it's easy to stay dry and comfortable. The problem is that every guest with a smart phone is getting the same shot, which makes it hard to justify your rate. Their shots will be just as good, and they'll be on Instagram within seconds.
If the only thing keeping you in business is the fact that the officiant asks guests not to take pictures during the ceremony, then you are doing something wrong.
Your confidence in the 'professional' weather sealing of the 5DIII is no doubt heartwarming for any naive 5DIII owners out there, but is misplaced. In reality the gaskets used on the 5DIII seem to be the same sponge strips that the 6D uses, and even Canon themselves state both camera's sealing levels are "the same as the film 1 series". It's worth remembering that even those last film cameras were not as much a mobile computer as to day's cameras are.
I would feel as vulnerable in heavy rain with a 5DIII as I would a 6D. Even with a 1D series, which do have proper rubber ring gaskets, most users try to give some protection in heavy rain.
The problem with shooting in a downpour is that water gets everywhere, including your front element, and as has been pointed out, lens hoods for a standard zoom are no use whatsoever. In practice I've found the only safe way to shoot in rain is to stop the rain reaching your camera in the first place.
I'm afraid your comments on wiping the front element or filter with a tissue rather give the game away when it comes to your experience. As I said earlier, water gets everywhere; your hands are wet, your coat and sleeves dripping in water. If you are wearing a hat it pours water down onto your camera as you look down. If you are not wearing a hat it runs off your hair and into your eyes. Remember this is a wedding you are talking about; things are happening quickly and wont be repeated. The only way I will shoot in the rain now is from under a large golfing umbrella, and even then it's a struggle to keep water off the camera.
