As the world has to attain the fulfilment of eternal life, to me it does not in the least matter what I am called -'Enlightened One', 'Son of God', or something else. To me, it has no purpose - as little as when the Buddha said, 'I am the Enlightened One'.
After all you grow by experience. But while your son is young, you should try to set before him his ultimate goal.
Buddha called himself 'The Enlightened One' and Jesus called himself 'The Son of God'. To me the term 'World-Teacher' is of as little importance as 'The Son of God' or 'The Enlightened One'.
