For all the length of reply, you end up with the same problem: according to whom?
It should be clear that those who claim to be led in different directions to different doctrines by the one Holy Spirit are in error.
So then you would saying what you did deny that both Paul and Peter were lead by The Holy Spirit? The Holy Spirit can not be in error. Churches can be in error be it Baptist, Catholic, whatever as well as even their highest leaders can be in error and in fact acting away from GOD's Will and guidance of The Holy Spirit. That is why The Holy Spirit which dwells in believers was given.
