That the doctrine of the trinity is false

The bible plainly teaches that God is a trinity, the watchtower society rejects the trinity because it does not seem logical to them.

The Father is God (1Cor 8:6, John 17:1-3, 2Cor 1:3, Phi 2:11, Col 1:3, 1Pet 1:2)

The Son is God (John 1:1, John 5:18, John 8:58, John 20:28, Titus 2:13, 2Pet 1:1)

The Holy Spirit is God (Acts 5:3-4 )

Trinity in the old testament (Isaiah 48:16-17)

Bible not enough?
