In the most biblical sense

Where I come from...or when I come from, men go by different names depending on their relationship with the speaker, and where they are, that sort of thing. Colleagues at work call you by your surname, old school friends call you by your school nickname, and if you're social in Soho you might have a queenly name down by the Dilly, and then family and others use your Christian name.

What I mean is, I'm not entirely sure any more what name you want me to use.
