Analysis of information sources in references of the Wikipedia article "Adoptionism" in English language version.
The most prominent example of Angel Adoptionism from the early Church would have to be the document known as The Shepherd of Hermass. In The Shepherd, the savior is an angel called the "angel of justification," who seems to be identified with the archangel Michael. Although the angel is often understood to be Jesus, he is never named as Jesus.
The Saviour, jesus Christ, who from the fullness (the pleroma) of the Father descended on earth, is identified with the Logos, but initially not entirely with the Only Begotten Son. In john 1:14 is written, after all, that his glory was as of the Only Begotten, from which is concluded that his glory must be distinguished from this (7, 3b). When the Logos or Saviour descended, Sophia, according to Theodotus, provided a piece of flesh (sarkion), namely a carnal body, also called 'spiritual seed' (1, 1).
[Per Jesus and Adoptionism] how does one understand the title "Son of God" when it is applied to Jesus? The answer is to be found in the Adoptionist movement within early Christianity. The Adoptionist trajectory in early Christianity begins with the baptism of Jesus by John the Baptist. According to the usual Adoptionist formulations, it was at his moment of baptism that Jesus moved into this special relationship or metaphorical "sonship" with God – not at his conception or virgin birth. [...] the oldest Greek manuscripts of and quotations from Luke render the key verse in question as follows. "Now when all the people were baptized, and when Jesus also had been baptized and was praying, the heaven was opened, and the Holy Spirit descended upon him in bodily form like a dove. And a voice came from heaven, "You are my son; today I have begotten you" (Luke 3:21-22)." [...] the wording regarding the baptism of Jesus is also to be found in Hebrews 1:5a, Hebrews 5:5, and Acts 13:33. This same wording is also found in Psalms 2:7 in reference to David and in the apocryphal Gospel of the Ebionites in reference to Jesus' baptism.
Ps 2:7-8 is also quoted in 1 Clem 36:4 and in Just. Dial. 122:6, whilst only verse seven of Ps 2 is found in the Ebionite Gospel (fr. 4) and in Just. Dial. 88:8, 103:6. The quotation from Ps 2:7 that occurs in Heb 1:5 and 5:5 found its way into Hebrews via the early Jewish and early Christian traditions.
The paucity of extant evidence makes an exact knowledge about the views of what modern scholars have dubbed "adoptionist" or 'dynamic' monarchianism uncertain. No documents written by adherents to this strain of Christian theology have survived. As a result, we cannot say what constituted a purely adoptionist viewpoint or how closely associated it was with what is typically called 'modalism'. True to its emphasis on divine monotheism, 'adoptionism' opposed any substantial division within God when it came to the incarnation of Christ as the Logos of God. As a result, the Jesus of the Gospels was a man empowered by the one God.
