Hello Brad!
Anyone can claim that the Holy Spirit reveals the Truth to them and so can another who claims to have the Holy Spirits teach a doctrine which is Contrary to the other persons belief, so who is correct? One can remain deceived because they refuse to hear the Truth of what the Scriptures plainly teach, rejecting the God inspired Truth found in scriptures alone.
Let the Word of God speak for itself, the question to all who claim to possess the Truth, let the Scriptures which are inspired by the Holy Spirit be the judge and no man. Let no man deceive you! The Question is, is that person willing to open their ears and hearts to it? That is why I will start from scratch to prove the theology of the Godhead as it is clearly explained away in SCRIPTURES, given by the Holy Spirit which is the Spirit of TRUTH! Can the Scriptures itself be wrong?
2 Timothy 3:16 - All scripture is given by (inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness.
God Bless!
