Are the titles "San" and "Santa" used before the name of cities and towns violate....?

the constitutionality of separation of church and state? I saw on TV whereby certain religious words such as god, blessing, etc. were deleted in the eulogy because some said it violated the separation of church and state since it was a government sponsored funeral. So what's next? The word "cross" seemed to have originated from the word "Crucifixion" so it should not be used to refer to an intersection? What about cities such as San Francisco, Santa Barbara, and especially Corpus Christi", a city in Florida? They violate the constitutionality of separation between church and state? Where does it stop?
