Trinitarians assert that ‘God is the Father, the Son, and the Holy Spirit’ all rolled into one God, but three entities at the same time. Of course, this makes no sense, but let’s see what the Bible says:
“We know that ‘An idol is nothing at all in the world’ and that ‘There is no God but one’. For even if there are so-called gods, whether in heaven or on earth (as indeed there are many ‘gods’ and many ‘lords’), yet for us there is one God, the Father . . . and there is but one Lord, Jesus Christ“—-1 Corinthians 8:4-6 NIV.
One thing we can infer from this is that worship of anything other than God the Father is idolatry. This is confirmed by:
“The true worshippers will worship the Father in the Spirit and in truth, for they are the kind of worshippers the Father seeks. God is spirit, and his worshippers must worship in the Spirit and in truth“—John 4:23,24 NIV.
Jesus here makes no allowance for worshipping the Son or the Holy Spirit!
The following 17 verses are some of the scriptures in the NT supporting the fact that God is the Father and he alone is called Father:
