Shalom,

I would not argue that YHVH is a TRINITY.
I would not argue that HE is also a singular being, a monotheos.
I would not argue that HE is a muti-theos.
What I would ask is, "What makes us think that HE is ONLY one of these?"
Arguably anyone that takes one of these positions has Biblical reasons to support their position, thus it becomes impossible for anyone to really dispute the others position as long as it too is founded in scripture.
At best all that we can really say is that, "This is the box that I put YHVH in!"
"This is what I believe!"

More important than this is for us to "hear what the SPIRIT is saying to the churches".
Rom 8:14 For as many as are led by the Spirit of God, they are the sons of God.
If we consider ourselves to be "of YHVH" then we must ask are we "SONS" of YHVH?
What we need to ask "what proof there is of this?
Are we acting like sons?
How?
Can anyone else tell?"

Most so-called CHRISTians spend their lives straining at gnats and never see the camels!
Their is a banquet spread before us.
The Harvest fields are ripe for harvest.
What will we do?
Will we ever really be about our FATHER's business of redeeming the lost?
Of setting the captives free?
Of healing the sick?
Of being representatives of HIM?
Will we ever get up and get out of our pews or do we need to get up and get out of our pews?
Rev 3:14 And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God;
Rev 3:15 I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot.
Rev 3:16 So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth.

shalom,

nice post and welcome to the board.

For me God is one with three seperate ways of manifesting Himself. We will not be able to completely 'wrap our minds around' that concept until the everlasting life.
