OK Aineo here is my argument for modelism:
God manifested(shown) in 3 modes
1)Father in creation
2)Son in redemption
3)Holy Spirit in infilling emanation/Regeneration
PHILIPPIANS 2:5-10,key verse 10
COLOSSIANS 1:20
1TIMOTHY 3:16..........This plainly shows how God was manifested in the mode of Son.
Please respond to the scriptures and show me how oness can be a false doctrine...............By these scriptures we are shown what the apostles believed and preached and that my friend was not a trinity.
