[This series is "The 9 Marks of a Calvinist Cult" split up into smaller, individual posts.]
Cults use isolation, control, fear, coercion, mind-control, and thought-reform to enslave the members to the cult. The members' "inner voices" are suppressed.
5. Information Isolation and Control
Of course, Calvinists don't physically isolate members in a commune or anything like that, as more extreme cults have. But Calvinist pastors do practice various forms of "mental" isolation by controlling the information and resources.
From the very beginning, Calvinist pastors set out to carefully control the information we get, the resources we have access to, the verses we hear, who's in charge, etc.
Verses: Calvinists will ignore verses that contradict or disprove Calvinism, but highly favor those that can be twisted/interpreted to support it.
For example: Calvinist pastors fill their sermons with verses that appear to fit their view that God preplans, causes, controls everything, such as Job 42:2 "... no plan of yours can be thwarted" and Proverbs 21:1 "The king's heart is in the hand of the Lord; he directs it like a watercourse wherever he pleases". [Notice that these verses record Job and Solomon's words about God.]
But they ignore verses that contradict their Calvinist views, such as Jeremiah 19:5 "They have built the high places to Baal to burn their sons in the fire as offerings to Baal - something I did not command or mention, nor did it enter my mind" and 1 Kings 20:42 "He said to the king, 'This is what the Lord says: 'You have set free a man I had determined should die.''" [Their response to a verse like this would be the ridiculous - and possibly blasphemous - "God decrees that people break His decrees." (And notice that these verses record God's own words about Himself.)]
