Tom,

Are you looking for a missionary-type individual specifically?

Of course, there is always the Apostle Paul. His theology was perfect, his life exemplary as a redeemed sinner and he certainly was influential on quite a number of people.

If I were you, the fact that your daughter would find this Shane Caiborne 'attractive' at all would be a concern for me. A simple substitution of an earthly model I think would be nothing more than a temporary band-aid and not deal with perhaps a far more serious problem.
