I get arguments from Trinitarians saying that Hebrews 1:3, 12:2; KJV prove Jesus is a separate person from God the Father.

What they fail to realize is this statement is a metaphor and proven as a metaphor by other scripture references as a symbol of same status God’s OMNIPOTENCE. Example: Joshua 4:24 KJV etc…

Brother Theodore has a wonderful study on the subject in the link below.

Trinity is Pagan Practice of Polytheism in Mainstream Christianity #EndTimes #Apostasy (thethirdheaventraveler.com)

Trinity and Modalism are Heretical Doctrine: Godhead is BIBLICAL and correctly defines God in true Christianity (thethirdheaventraveler.com)
