Hi Pneuma,
I'm not evading your questions, I have debated here at length before answering the same old questions. You have your heart set that God is not triune, and that is up to you to do so.
I have agve you on another thread regarding John 17 and the personal pronouns that are both in the Greek and English text, and you cannot say as you tried to, that it is just 'Language'. For it is by language that we can understand that God Almighty Himself chose to reveal Himself and His work in creation and History and the future.
Anyhow, Something for you to think about.
Why did God create man?
was God Lonely and he wanted someone to relate to, have a relationship with?
God is love, each person in the trinity love one another in perfect harmony, they are co equal, co eternal yet, the Father sends the Son, the son Sends the Holy Spirit.
Man has the ability and desire to be in loving relations, thats with friends, wives/husbands, because we were created to be like God, a relational being.
Anyhow, We could go on and on and on, I believe from Scripture that God is triune, I Know we will never be able to know the depths and complexities of the Godhead, but we can gleam what God has revealed. I know that without God being a perfect relation being with each person of the trinity, I would not desire relationships in the same way.
I cannot force you to believe what you do not want neither do I desire too. You have said you were once a Trinitarian, but I also know there are many 'oneness' believers who have seen the real glory of God.
I humbly pray that you too, se the great Glory of the Godhead in God's glorious relational love.
