Three person “trinity” is not biblical and comes from pagan idolatry.
We should not use philosophy and traditions of men to try and describe the Godhead (Col 2:8-9).
We are not to represent the Godhead using our own art and device (Acts 17:29).
When we go beyond what God’s words actually say we create idols of our own understanding (Hosea 13:2).
The bible word is “Godhead” and the definition of Godhead is
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.
One God (Deut 6:4; 1 John 5:7), one person (Col 2:8-9; 2 Cor 2:10; Heb 1:1-3), three members (1 John 5:7; 1 Cor 12:12).
