1 John 5:7 "For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one." KJV
........at our church,...we sing,...."Holy,Holy,Holy,...'ONE'-God in three persons,...BLESSED TRINITY!"
all stanzas....
ONE-GOD,....simply add the word 'One'....works VERY well!
Shalom ev Echud!!!
Maranatha!
(Romans 10:17)
But for the New Testament stuff, I think you might be on to something.
