Well let’s look at what the title Christ means. Christos is the Greek translation of Mashiach - the Jewish messiah. Both mean “the anointed one”.
But what does that mean? It means chosen for a special purpose. This was often marked out by the anointing of oil, eg the anointing of kings and priests.
In Judaism the Messiah was to have the special purpose of saving the Jews. Although from memory there have been several Mashischs identified St Cyprian comes to mind - but would need to check my memory is shit these days.
Therefore, anyone chosen for a special purpose by the divine can become Christ on the fulfilment of this purpose (Jesus arguably only fully became Christ after he died).
From Mark (really the only synoptic gospel I pay much notice of) it appears God chose Jesus after his baptism.
In the world I inhabit, everyone has a divinely created purpose, often called their “True Will” The spiritual journey is finding out what this is and realising it, often through self sacrifice (like the crucifixion).
Christ consciousness is reaching an enlightenment on an intellectual, emotional and spiritual level and has been reached across time and geography, eg the Buddha.
There is no need to recognise Jesus’s “authority” he’s a good example and offers much guidance but his purpose was different to mine, God chose him for a different task.
