This is said no where in the Bible. Jesus continually confirmed that he was the Son and never God. There is a clear distinction throughout the Bible. The Trinity is a man made tradition. John 1:1 does not support a Trinity because John didn't believe in a trinity. John is speaking of the Word, God's Word.

Genesis 1:26 also does not even hint at a Trinity. God is speaking to the Holy Angels who were present at the Creation and are also made in his image.

To make God three is blasphemy. The pagan gods are three. My God is one.
