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
