Fellow ejected from chapel, the German high-up in congregation (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
elder
'high-up in congregation' is the definition.
I don't understand the remainder of the clue.
(Other definitions for elder that I've seen before include "Patriarch" , "Layman of the church" , "Senior member of a tribe" , "White-flowered tree" , "Tree and Mormon church officer" .)
