The original sense of "flock" as defined by Merriam-Webster.
Evangelist’s Flock Keeps the Faith After His Brush With the Law. (The New York Times, 8/30/2013)
Excerpt: Facing prosecution on a charge of impersonating a law enforcement officer, Mr. Pitt, 30, might not in fact return soon to his ministry and its services, which are known for earsplitting playlists, strobe lights and smoke machines.
Depending on who tells the story,
Mr. Pitt’s fall is either that of a young preacher who rose too far too fast and thought he was above the law or, as his followers believe, a plot aimed at pulling down a man responsible for the development of their spiritual identities. Either way, it is a tale of central Alabama, a region dotted with churches and youth groups.
