Only as concerns what is already said in Scripture, such as the following:
Luke 12:11 And when they bring you unto the synagogues, and unto magistrates, and powers, take ye no thought how or what thing ye shall answer, or what ye shall say:
12 For the Holy Ghost shall teach you in the same hour what ye ought to say.
But Scripture already says that if any kind of revelation contradicts God’s Words or commands, then that revelation is not of God. The Scripture also says that the Holy Spirit is our teacher, guide, and comforter; but again, the Holy Spirit would not be divided against Himself and “teach another gospel” than Christ’s.
Well, then how do you explain all the doctrinal differences amongst groups that you DO accept as Christian?
