One churchman or another welcoming company (6)

I believe the answer is:

deacon

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

'one churchman' is the definition.
(I've seen this before)

'another welcoming company' is the wordplay.
'another' becomes 'dean' (I can't justify this - if you can you should give a lot more credence to this answer).
'welcoming' is an insertion indicator (in sense of 'inviting in').
'company' becomes 'co' (abbreviation).
'dean' placed around 'co' is 'DEACON'.

'or' acts as a link.

Can you help me to learn more?

(Other definitions for deacon that I've seen before include "Ordained cleric" , "Minister below a priest" , "An ordained minister" , "Church officer" , "Clergyman of low rank" .)
