Possessive of Jesus 

There are a couple of editors changing "Jesus'" to "Jesus's". Does Wikipedia have a preference here? The rule I learned was that for proper names, you add  's even if it ends in s, unless the name is an ancient name containing at least one other s (Jesus being the most common example). It's kind of an arbitrary rule, but I can certainly say that I've seen Jesus''' a lot more than Jesus's'', and I read a lot on the subject...  07:47, Oct 23, 2004 (UTC)
