The Trinity is Biblical

I apologize profusely for not answering in the last round, my country is currently in a civil crises, and "revolutionary" protesters thought it their "democratic responsibility" to burn down the buildings of the government. Including my internet provider's whose servers were located next to the building owned by the government. Cheerful, no? I feel that my opponent does not have a clear conception of the Trinity. I should note that a lot what I say is from Saint Augustine's book De Trinitate. Where I have mentioned St. Augustine's words, I mean this book. Let us understand that God the Father, God the Son, and the Holy Spirit are not one physical entity. In so far as physical (whatever constitutes for physical for the Father, and Spirit) is concerned, they are a Trinity of three persons. It is rather is Geistes that they are One and the Same. So physically as St. Augustine says: '. .. the Father does some things, the Son others, and the Holy Spirit yet others;'. This is an important distinction for it was only the Father who proclaimed Jesus His Son (Mark 1:11). Similarly it was the Son who was born of a virgin, and the Holy Spirit alone who appeared as the dove to John. The important distinction here between the Father, and the Son (in terms of physical attributes (because my opponent mostly sticks to Jesus)) is that things are "from" the Father, and "through" the Son. This is a very important distinction, and we shall now show from Scripture, and connect this to show why "through" here is most important. Verily, it is the Father whose will is the greatest, but it is through another form of the Father, mainly Jesus. Let us then present the celebrated verse: 'In the beginning was the Word, and the Word was with God, and the Word was God'. (John 1:14). It is clear that this Word through which this Word became common word is Jesus, and we are told this from the verse '. .. and the Word became flesh'. (John 1:14) So we know that Jesus was immortal, in so far as He too was always there. We also know, beyond doubt, from Scripture that Jesus was in fact God. While Jesus was not the Father, and the Father was not Jesus, they were One is Geistes. For things must come from the Father, but through Jesus. Here John explicitly mentions it in one of the verses of the Bible. Similarly we have John's testimony again when he says: 'We know that the Son of God has come, and has given us understanding to know the True One, and "to be in the true one", in His Son Jesus Christ. This is the true God, and life everlasting'. (John 5:20) This once again shows how Jesus is in fact one with God the Father. Jesus was both Man and God, he was separate from the Father, and yet connected in Spirit. Similarly connecting to this we can conclude that Paul's words "who alone has immortality" (Tim 6:16) refer to the Spirit of God, including both Jesus, the Father, and the Spirit. Another reference is to the sameness of the Father and of Jesus when the Bible says: 'whatever the Father does, the Son also does likewise" (John 5:19); one more reference of sameness is: 'As the Father raises the dead and gives them life, so also the son gives life to whom he wills'. (John 5:21). In the Greek the possession of "he" is given to the Son meaning the Son does in fact have Will. So in fact it is pointless to argue that the Bible does not support the Trinity when even (I Corinthians 11:3) state: 'But the head of Christ is God". I leave with one question, if my opponent doubts the Trinity is biblical then he needs to provide an alternate. Pray tell, if Jesus is not the Son of God, who is Jesus? If Jesus is not God, or does not resemble God then what was he? My opponent needs to answer these questions for I have provided sufficient evidence of the Biblicality of the Trinity.
