Here is one false idea: that the Father and the HolySpirit are different persons.

Trinitarians believe in Father, Son and HolySpirit. But -> The HolySpirit is the Father of Jesus Christ Mat 1:18,20 -> God is a Spirit Joh 4:24 -> Since there is one Spirit, God is the HolySpirit Eph 4:4 -> Jesus is the express image of the Father Heb 1:3 -> Jesus and His Father are One Joh 10:30 -> Jesus has all power in heaven and earth Mat 28:18

-> The HolySpirit raised Jesus from the dead Rom 8:11 -> Jesus raised Himself from the dead Joh 10:17 -> Hence the SpiritOfChrist is the HolySpirit -> Jesus is God Isa 9:6 -> There is no other God Deu 6:4 -> It is forbidded to worship any other person Mat 4:10.
