However, of the lenses that you have in your profile I would use your: 50 and 135 mm, you should be able to move around so you will not need the zoom as much as the opening due to the lower light conditions indoor. However if you rob a bank I still recommend the above lenses.
That would be a good choice if you could only have one lens.
By the way...The 70-200mm lens is not just for long zooming for sports or wildlife like many people might think. It is one of the best portrait lens lengths you can get.
Check out Joe McNally's site. He is a world reknown photographer and a lot of his best portraits are done with a 70-200mm. And with flash you don't need to worry about camera shake.

The 70-200 would have been my second choice and the 17-35 my close third. I just wouldn't be changing lenses during the ceremony, so I'd just pick one. I'd pick one that would work in poor lighting conditions and be able to zoom from a close-up portrait to a crowd. Now,... the before and after ceremony shots I would probably have time to get creative in all kinds of ways. That may take a few lens changes.
