Member of the United Society of Believers in Christ's Second Coming (6)

I believe the answer is:

(Other definitions for shaker that I've seen before include "Drinks mixer" , "One gets agitated" , "Member of American Christian sect" , "One 24 [IN-SECT]" , "Religious type" .)

I've seen this clue in The Guardian.
