apotheosis

I'm a little stuck... Click here to teach me more about this clue!

'high point' is the definition.
'apotheosis' can be an answer for 'point' (I have seen 'Crowning point ' mean 'apotheosis' so perhaps 'point' could also mean 'apotheosis'). I am unsure of the 'high' bit.

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for apotheosis that I've seen before include "ideal" , "Given maximum promotion" , "glorification" , "Perfect example" , "Elevation to divine status" .)

I've seen this clue in The Telegraph.
