Question: Whose position was it that the speaker in the sermon on the mount was the Son of God?

full_context: Document 1: Parable of the Faithful Servant: The Parable of the Faithful Servant (or Parable of the Door Keeper) is a parable of Jesus found in Matthew 24: 42 - 51, Mark 13: 34 - 37, and Luke 12: 35 - 48 about how it is important for the faithful to keep watch.
Document 2: 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 3: 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 4: 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.
Document 5: Matthew 4:4: Matthew 4: 4 is the fourth verse of the fourth chapter of the Gospel of Matthew in the New Testament. Jesus, who has been fasting in the desert, has just been encouraged by Satan to make bread from stones to relieve his hunger, in this verse he rejects this idea.
Document 6: Matthew 7:7–8: Matthew 7: 7 -- 8 are the seventh and eighth verses of the seventh chapter of the Gospel of Matthew in the New Testament and is part of the Sermon on the Mount. These verses begin an important metaphor generally believed to be about prayer.
Document 7: Matthew 6:33: Jesus has just told his followers not to worry about material things such as food or clothing, as God will provide the needs of his followers. Earlier in the chapter Jesus presented a discussion on how one must not pursue wealth and material things before God. This verse ties the two notions together. If one places the pursuit of the Kingdom of God first, then material needs will follow without need for worry or anxiety. The present imperative verb seek makes clear that pursuing the eschatological kingdom is not a passive act, but one that must be pursued with rigour. Hill notes that the word God is left out of many of the better early manuscripts of the Gospel, and it thus might be a later addition. Kingdom of God is a somewhat unusual phrase, with the author of Matthew generally preferring Kingdom of Heaven. Even without the word it is quite clear that this is a reference to the Kingdom of God. The parallel to this verse at Luke 12: 31 does not mention righteousness, but as France notes the author of Matthew shows a special interest in righteousness throughout his gospel.
Document 8: Parable of the Great Banquet: The Parable of the Great Banquet or the Wedding Feast or the Marriage of the King's Son is a parable told by Jesus in the New Testament, found in Matthew Matthew 22: 1 - 14 and Luke Luke 14: 15 - 24.
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: 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 11: 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 12: Parable of the Sower: The Parable of the Sower (sometimes called the Parable of the Soils) is a parable of Jesus found in the three Synoptic Gospels in Matthew 13: 1 - 23, Mark 4: 1 - 20, and Luke 8: 1 - 15. In the story, a sower sows seed; some seed falls on the path (way side), on rocky ground and among thorns, and it is lost, but when it falls on good earth it grows, yielding thirty, sixty, and a hundredfold.
Document 13: Sermon on the Mount: The Sermon is the longest continuous section of Jesus speaking found in the New Testament, and has been one of the most widely quoted elements of the Canonical Gospels. It includes some of the best known teachings of Jesus, such as the Beatitudes, and the widely recited Lord's Prayer. The Sermon on the Mount is generally considered to contain the central tenets of Christian discipleship.
Document 14: Gospel of John: The Gospel of John can be divided into four sections: a prologue (1: 1 -- 18), a Book of Signs (1: 19 -- 12: 50), a Book of Glory (13: 1 -- 20: 31), and an epilogue (21). The structure is highly schematic: there are seven ``signs ''culminating in the raising of Lazarus (foreshadowing the resurrection of Jesus), and seven`` I am'' sayings and discourses, culminating in Thomas's proclamation of Jesus as ``my lord and my God ''-- the same title (dominus et deus) claimed by Roman Emperor Domitian.
Document 15: 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).
