I thought I'd repost a question I asked four years ago, before we had comments: Why is Jesus a common name in Spanish-language cultures, but to my knowledge no other European-language cultures? (I don't know about Portuguese-language cultures; perhaps they're like the Spanish-language.)

It can't just be Christianity, or even Catholicism: I've never heard of Frenchmen, Italians, Poles, or Irishmen with that name. There's nothing theologically wrong with either approach, I'm sure -- but why is it that one huge part of Christendom embraces the name Jesus for its sons, while another rejects it almost entirely?
