Read it again s l o w l y I did not call you blasphemous, but rather to say Christ was not born the son of God until immersion....
Emmanuel was born the son of God when he was conceived as the son of God in Mary and by Holy Spirit.
The Holy Spirit descended upon Emmanuel after immersion to show those who looked on the meaning of the teaching Emmanuel would give them concerning being born of spirit and water.
Emmanuel, "God with us", Jesus, taught in parables , as he said, so that not all would understand. You have not one legitimate scripture that can support your contention.
Emmanuel/Jesus was referred to extensively even in the old testament.
