Matthew 3:16,17 - Was There a Triune God at Jesus' Baptism?

Matthew 3:16 Jesus, when he was baptized, went up directly from the water: and behold, the heavens were opened to him. He saw the Spirit of God descending as a dove, and coming on him.
Matthew 3:17 Behold, a voice out of the heavens said, "This is my beloved Son, in whom I am well pleased.

Mark 1:9 It happened in those days, that Jesus came from Nazareth of Galilee, and was baptized by John in the Jordan.
Mark 1:10 Immediately coming up from the water, he saw the heavens parting, and the Spirit descending on him like a dove.
Mark 11:11 A voice came out of the sky, "You are my beloved Son, in whom I am well pleased."

Luke 3:21 Now it happened, when all the people were baptized, that, Jesus also having been baptized, and praying, the sky was opened,
Luke 3:22 and the Holy Spirit descended in a bodily form, as a dove on him; and a voice came out of the sky, saying "You are my beloved Son. In you I am well pleased." 

John 1:29 On the next day, he [John the Baptist] saw Jesus coming to him, and said, "Behold, the Lamb of God, who takes away the sin of the world!
John 1:30 This is he of whom I said, 'After me comes a man who is preferred before me, for he was before me.'
John 1:31 I didn't know him, but for this reason I came baptizing in water: that he would be revealed to Israel."
John 1:32 John testified, saying, "I have seen the Spirit descending like a dove out of heaven, and it remained on him.
John 1:33 I didn't recognize him, but he who sent me to baptize in water, he said to me, 'On whoever you will see the Spirit descending, and remaining on him, the same is he who baptizes in the Holy Spirit.'
John 1:34 I have seen, and have testified that this is the Son of God."

According to Augustine, here "the Trinity appears very clearly: the Father in the voice, the Son in the man, the Spirit in the dove." Do we actually find anything in the scriptural accounts above of Jesus' baptism that presents any concept that the God of Abraham, Isaac and Jacob is more than one person, that he is three persons, and that the Father, the Son and Holy Spirit are those three persons? Actually, not at all. As in all scriptures trinitarians present, the concept has to be formulated by thinking beyond what is written, and creating many assumptions that have to be added to and read into what is written in order to "see" the trinity in what is written.

In John's account above, we find Jesus and the Holy Spirit mentioned, but then "God" is presented as only one person, not three, in John 1:34. In the first three accounts, we do find that the voice of the only true God is heard from heaven, and that the spirit of the only true God descends on Jesus, but there no mention at all that these three are persons of the only true God. Thus, the trinitarian has to first imagine, assume, add to, and read into the scriptures that the God of Abraham, Isaac and Jacob (Acts 3:13) is more than one person, and further imagine, assume, add to, and read into the scriptures that the "one Jehovah" (Deuteronomy 6:4) is three persons, and then further imagine, assume, the Father whose voice is heard is one of the persons, and then further imagine, assume, add to and read into the scriptures that the Son of the "one God" of 1 Corinthians 8:6 is another person of the one Jehovah, and then further imagine, assume, and add to the scriptures that God's holy spirit is another person of the "one Jehovah." They then further imagine, assume, add to, and read into the scriptures that Son of God who was baptized was two natures, alleged to be both fully God (the Supreme Being) and fully man (a human being), and thus the imagined "God the Son" was dwelling in the human flesh of Jesus, the human son of God. The reality is that none of these scriptures, nor any scriptures in the entire Bible present such assumptions.

Rather than focusing on what has to be imagined and assumed regarding these scriptures, it is best to focus on Jesus' baptism itself and compare spiritual revealing with spiritual revealing in order to see what his baptism means. In short, Jesus was baptized in symbolism of his consecration to offer himself to his God for our sins. To understand the details of this, however, means to chew on the strong meat of the Bible, which most Christians will not do; most appear to be content to remain "babes in Christ". -- 1 Corinthians 3:1.

Before Jesus came into the world, he was sanctified -- consecrated -- before God to do God's will. (John 10:36) Although Jesus was born under Law (Galatians 4:4), he was not brought into this world under the condemnation in Adam. (Romans 5:12-19; 1 Corinthians 15:21,22) And yet he willingly took upon himself not only the condemnation in Adam, but also the curse of the Law, so that Israel could be freed from that curse, and the world condemned in Adam could be saved from the condemnation in Adam.

What we do not find in any of the scriptures presented is the idea that Jehovah, the God of Abraham, Isaac and Jacob (Exodus 3:14,15) is more than one person, or that He is three persons, or that Jesus is a person of the God of Abraham, Isaac and Jacob. Actually, Peter presents the God of Abraham, Isaac and Jacob as only one person and presents Jesus, not as being the God of Abraham, Isaac and Jacob, but rather the servant of the God of Abraham, Isaac and Jacob. Peter presents the God of Abraham, Isaac and Jacob as the one who raised up his servant as the prophet like Moses. -- Acts 3:13-26; Deuteronomy 18:15-19.
