They spoke their minds and what they felt was right even if it meant scorn and rejection from the people they knew and loved best.
Yes, Paul and other early Christians did. And early Watchtower publications support this. For example the book Thy Kingdom Come (1911), pp 184-185, warns against joining "human organizations" because those doing so will "bind themselves to believe neither more nor less than the creed expresses on the subject."
And if they "think for themselves," or 'speak their own minds' as you have expressed it, they will have to "come out of such a sect."
The same publication observes that to do this will "cost some effort, disrupting, as it often does, pleasant associations, and exposing the honest truth-seeker to the silly charges of being a "traitor" to his sect, a "turncoat," one "not established," etc."
It goes on to say, "When one joins a sect, his mind is supposed to be given up entirely to that sect, and henceforth not his own. The sect undertakes to decide for him what is truth and what is error."
Today the Watchtower says that everyone must think alike, in order to be united as Christians. Not only is it unacceptable to talk about something the Society doesn't teach, Witnesses today are warned against even 'harboring private ideas.' The only beliefs that are acceptable are those of the leadership, which has been deemed to be the governing body of the "faithful and discreet slave."
To 'speak one's own mind and what he felt was right' would today be viewed as a 'defection, an abandonment, a falling away from the teachings of the slave,' and the person would be disfellowshipped for apostasy.
Sadly, the WTS has adopted the controlling methods it once warned against.
