Minister full of energy facing a church is most inclined to sermonise (10)

I believe the answer is:

preachiest

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

'most inclined to sermonise' is the definition.
I can't judge whether this defines the answer.

'minister full of energy facing a church' is the wordplay.
'minister' becomes 'priest' (a church minister).
'full of' is an insertion indicator.
'energy' becomes 'e' (physics symbol as in E=mcr).
'facing' says to put letters next to each other.
'church' becomes 'ch' (common abbreviation).
'e'+'a'+'ch'='each'
'priest' enclosing 'each' is 'PREACHIEST'.

'is' is the link.

Can you help me to learn more?

(Another definition for preachiest that I've seen is " Extremely sanctimonious".)
