You are only kidding yourself when you deny Catholics serve Mary with statues, prayers, and etc., which is serving a creature instead of the Creator.
The Trinity is God in three persons. The Godhead is according to the Trinity 1/3 the Father, 1/3 the Son, and 1/3 the Holy Spirit. This Believer is simple math. 1/3 X 3= 1, but 1+1+1=3 not 1. Your explanation of the Trinity is more Jesus only oneness that the orthodox doctrine of the Trinity, which is 3 distinct persons in one Godhead.
Your insistence that I do not understand the doctrine of the Trinity is a bit arrogant since you are not God's spirit who is the only Spirit who knows what is the mind of any man and God knows I understand this false doctrine. I defended it for decades until the Lord opened my mind to understand God's word, just like He did for the apostles.
Your poor attempt to appeal to one translation while ignoring the balance of Scripture only shows your pride is trying to override God's revealed truth. But then what should I expect from a man who belongs to a church that teaches purgatory, the Papacy, the Marina doctrines, praying to the physically dead, and etc. All of which are concepts derived from pagan beliefs and Greek philosophies that are the antithesis of God's will and truth.
