jesus is actually depicted as walking on water, so it's correct to point that out, but he's not depicted as belonging to an anachronistic racial category, so I thought it was worth correcting that point

I think walking on water is best seen as a very effective literary device, rather than a literal description of an event that took place

also walking on water isn't necessarily physics-defying, for example certain insects do it, as in the notorious W. B. Yeats poem -- and if it gets cold enough it's a pretty ordinary thing to do
