Question: Whose position was it that the first person baptized in the bible was the Son of God?

full_context: Document 1: Athanasius of Alexandria: Conflict with Arius and Arianism as well as successive Roman emperors shaped Athanasius's career. In 325, at the age of 27, Athanasius began his leading role against the Arians as his bishop's assistant during the First Council of Nicaea. Roman emperor Constantine the Great had convened the council in May–August 325 to address the Arian position that the Son of God, Jesus of Nazareth, is of a distinct substance from the Father. Three years after that council, Athanasius succeeded his mentor as archbishop of Alexandria. In addition to the conflict with the Arians (including powerful and influential Arian churchmen led by Eusebius of Nicomedia), he struggled against the Emperors Constantine, Constantius II, Julian the Apostate and Valens. He was known as "Athanasius Contra Mundum" (Latin for Athanasius Against the World).
Document 2: Athanasius of Alexandria: Throughout most of his career, Athanasius had many detractors. Classical scholar Timothy Barnes relates contemporary allegations against Athanasius: from defiling an altar, to selling Church grain that had been meant to feed the poor for his own personal gain, and even violence and murder to suppress dissent. Athanasius used "Arian" to describe both followers of Arius, and as a derogatory polemical term for Christians who disagreed with his formulation of the Trinity. Athanasius called many of his opponents "Arian", except for Miletus.
Document 3: Baptists: Historians trace the earliest church labeled ``Baptist ''back to 1609 in Amsterdam, Dutch Republic with English Separatist John Smyth as its pastor. In accordance with his reading of the New Testament, he rejected baptism of infants and instituted baptism only of believing adults. Baptist practice spread to England, where the General Baptists considered Christ's atonement to extend to all people, while the Particular Baptists believed that it extended only to the elect. Thomas Helwys formulated a distinctively Baptist request that the church and the state be kept separate in matters of law, so that individuals might have freedom of religion. Helwys died in prison as a consequence of the religious persecution of English dissenters under King James I. In 1638, Roger Williams established the first Baptist congregation in the North American colonies. In the mid-18th century, the First Great Awakening contributed to Baptist growth in both New England and the South. The Second Great Awakening in the South in the early 19th century greatly increased church membership. Baptist missionaries have spread their faith to every continent.
Document 4: Baptism in early Christianity: At the start of his ministry, Jesus was baptized by John the Baptist. Critical scholars broadly agree that the baptism of Jesus is one of the most authentic, or historically likely, events in the life of the historical Jesus. Christian baptism has its origin in the baptism of Jesus, in both a direct and historical sense. Many of the earliest followers of Jesus were people who, like him, were baptized in the Jordan by John the Baptist.
Document 5: Protestantism: Historians trace the earliest church labeled Baptist back to 1609 in Amsterdam, with English Separatist John Smyth as its pastor. In accordance with his reading of the New Testament, he rejected baptism of infants and instituted baptism only of believing adults. Baptist practice spread to England, where the General Baptists considered Christ's atonement to extend to all people, while the Particular Baptists believed that it extended only to the elect. In 1638, Roger Williams established the first Baptist congregation in the North American colonies. In the mid-18th century, the First Great Awakening increased Baptist growth in both New England and the South. The Second Great Awakening in the South in the early 19th century increased church membership, as did the preachers' lessening of support for abolition and manumission of slavery, which had been part of the 18th-century teachings. Baptist missionaries have spread their church to every continent.
Document 6: Athanasius of Alexandria: In about 319, when Athanasius was a deacon, a presbyter named Arius came into a direct conflict with Alexander of Alexandria. It appears that Arius reproached Alexander for what he felt were misguided or heretical teachings being taught by the bishop. Arius's theological views appear to have been firmly rooted in Alexandrian Christianity, and his Christological views were certainly not radical at all. He embraced a subordinationist Christology which taught that Christ was the divine Son (Logos) of God, made, not begotten, heavily influenced by Alexandrian thinkers like Origen, and which was a common Christological view in Alexandria at the time. Support for Arius from powerful bishops like Eusebius of Caesarea and Eusebius of Nicomedia, further illustrate how Arius's subordinationist Christology was shared by other Christians in the Empire. Arius was subsequently excommunicated by Alexander, and he would begin to elicit the support of many bishops who agreed with his position.
Document 7: Baptists: Another milestone in the early development of Baptist doctrine was in 1638 with John Spilsbury, a Calvinistic minister who helped to promote the strict practice of believer's baptism by immersion. According to Tom Nettles, professor of historical theology at Southern Baptist Theological Seminary, "Spilsbury's cogent arguments for a gathered, disciplined congregation of believers baptized by immersion as constituting the New Testament church gave expression to and built on insights that had emerged within separatism, advanced in the life of John Smyth and the suffering congregation of Thomas Helwys, and matured in Particular Baptists."
Document 8: Athanasius of Alexandria: However Cornelius Clifford places his birth no earlier than 296 and no later than 298, based on the fact that Athanasius indicates no first hand recollection of the Maximian persecution of 303, which he suggests Athanasius would have remembered if he had been ten years old at the time. Secondly, the Festal Epistles state that the Arians had accused Athanasius, among other charges, of not having yet attained the canonical age (30) and thus could not have been properly ordained as Patriarch of Alexandria in 328. The accusation must have seemed plausible. The Orthodox Church places his year of birth around 297.
Document 9: Athanasius of Alexandria: Athanasius also wrote a two-part Against the Heathen and The Incarnation of the Word of God. Completed probably early in his life, before the Arian controversy, they constitute the first classic work of developed Orthodox theology. In the first part, Athanasius attacks several pagan practices and beliefs. The second part presents teachings on the redemption. Also in these books, Athanasius put forward the belief that the Son of God, the eternal Word through whom God created the world, entered that world in human form to lead men back into the harmony from which they had earlier fallen away.
Document 10: Baptists: Historians trace the earliest Baptist church back to 1609 in Amsterdam, with John Smyth as its pastor. Three years earlier, while a Fellow of Christ's College, Cambridge, he had broken his ties with the Church of England. Reared in the Church of England, he became "Puritan, English Separatist, and then a Baptist Separatist," and ended his days working with the Mennonites. He began meeting in England with 60–70 English Separatists, in the face of "great danger." The persecution of religious nonconformists in England led Smyth to go into exile in Amsterdam with fellow Separatists from the congregation he had gathered in Lincolnshire, separate from the established church (Anglican). Smyth and his lay supporter, Thomas Helwys, together with those they led, broke with the other English exiles because Smyth and Helwys were convinced they should be baptized as believers. In 1609 Smyth first baptized himself and then baptized the others.
Document 11: Crucifixion of Jesus: The baptism of Jesus and his crucifixion are considered to be two historically certain facts about Jesus. James Dunn states that these "two facts in the life of Jesus command almost universal assent" and "rank so high on the 'almost impossible to doubt or deny' scale of historical facts" that they are often the starting points for the study of the historical Jesus. Bart Ehrman states that the crucifixion of Jesus on the orders of Pontius Pilate is the most certain element about him. John Dominic Crossan states that the crucifixion of Jesus is as certain as any historical fact can be. Eddy and Boyd state that it is now "firmly established" that there is non-Christian confirmation of the crucifixion of Jesus. Craig Blomberg states that most scholars in the third quest for the historical Jesus consider the crucifixion indisputable. Christopher M. Tuckett states that, although the exact reasons for the death of Jesus are hard to determine, one of the indisputable facts about him is that he was crucified.

In accordance with his reading of the New Testament, he rejected baptism of infants and instituted baptism only of believing adults. Baptist practice spread to England, where the General Baptists considered Christ's atonement to extend to all people, while the Particular Baptists believed that it extended only to the elect.

Baptist missionaries have spread their church to every continent.
Document 13: Athanasius of Alexandria: Athanasius's first problem lay with Meletius of Lycopolis and his followers, who had failed to abide by the First Council of Nicaea. That council also anathematized Arius. Accused of mistreating Arians and Meletians, Athanasius answered those charges at a gathering of bishops in Tyre, the First Synod of Tyre, in 335. There, Eusebius of Nicomedia and other supporters of Arius deposed Athanasius. On 6 November, both sides of the dispute met with Emperor Constantine I in Constantinople. At that meeting, the Arians claimed Athanasius would try to cut off essential Egyptian grain supplies to Constantinople. He was found guilty, and sent into exile to Augusta Treverorum in Gaul (now Trier in Germany).
Document 14: Infant baptism: From at least the 3rd century onward Christians baptised infants as standard practice, although some preferred to postpone baptism until late in life, so as to ensure forgiveness for all their preceding sins.
Document 15: Athanasius of Alexandria: T. Gilmartin, (Professor of History, Maynooth, 1890), writes in Church History, Vol. 1, Ch XVII: On the death of Alexander, five months after the termination of the Council of Nice, Athanasius was unanimously elected to fill the vacant see. He was most unwilling to accept the dignity, for he clearly foresaw the difficulties in which it would involve him. The clergy and people were determined to have him as their bishop, Patriarch of Alexandria, and refused to accept any excuses. He at length consented to accept a responsibility that he sought in vain to escape, and was consecrated in 326, when he was about thirty years of age.
