Ramoss doesn't seem to be talking about cults, which do seem to brainwash and do some extreme fleecing.
A cult and a religion are, in my eyes at least, essentially the same thing.
There's a big difference between changing religions and signing over your house.
But the methods used to elicit either action may be very similiar if not the same.
Even if you feel a person was "brainwashed", is the conversion valid? Would God accept a manipulated decision?
Here's the way I would see it. If a man is told God is great and Christ is the Saviour, etc, and he chose not to accept it, then that's that. If someone manipulates him to believe it, then they are appealing to a different interest and so the reason for believing in God and Christ are not as they should be (out of pure faith) but for reasons relating to the manipulation (give them money, pretend your Jewish, etc).
I don't feel that Jesus or the writers of the NT suggested strong arm tactics. Paul seemed to use a bit of deception, but did he pressure people? His writings don't give me that impression.
No, they may not have pressured anyone, but manipulation is manipulation, whether forced or not.
