Actually, I think I was misunderstood. I was actually saying the opposite. According to good ol' Strunk and White:

1. Form the possessive singular of nouns by adding 's. Follow this rule whatever the final consonant. Thus write,

Charles's friend
Burns's Poem
the witch's malice

Exceptions are the possessives of ancient proper names ending in -es and -is, the possessive Jesus', and such forms as for conscience' sake, for righteousness' sake. But such forms as Moses' Laws, Isis' temple are commonly replaced with,

The laws of Moses
The temple of Isis
