Welshman takes time welcoming key priest and preacher (10)

I believe the answer is:

evangelist

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

'preacher' is the definition.
(an evangelist spreads or preaches their religion)

'welshman takes time' is the wordplay.
'welshman' becomes 'Evan' (common Welsh name).
'takes' becomes 'gelis' (I can't justify this - if you can you should believe this answer much more).
'time' becomes 't' (abbreviation).
'evan'+'gelis'+'t'='EVANGELIST'

'welcoming key priest and' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for evangelist that I've seen before include "Zealous believer" , "Preacher" , "Gospel writer" , "Gospel spreader" , "Mark for one" .)
