We used a similar solution for WordNet [1]. It is the minimal thing 
you can do to prevent mistakes, but leaves one with the problem of 
working with multiple versions of the vocab.

Complicating matter is that what constitutes a good mapping might 
differ between applications. For one application a small difference 
between peaches1 and peaches2 might not matter, for another it might.

It seems an open problem; in general there seem to be no established 
practices for versioning in the RDF/OWL community.

Sounds like a case for SKOS mapping. Different URIs for the editions, 
map the Christianity ones on each other.

Another solution might be to distinguish between the (global) URI and 
(local) edition identifiers. Christianity would get one global URI and 
two properties to define the local ID per edition.
