Gay Species tried to comment on this thread. But since Positive Liberty has been having problems with our comments section, it didn't go through. I have reproduced it here.
Unitarian or Trinitarian? Christ’s Dual Natures? Is Priestly Corrupting Christianity?
The Sources of Revelation
Dei verbum: Sacred Tradition and sacred Scripture, then, are bound closely together, and communicate one with the other . . . and make up a single deposit of the Word of God, which is entrusted to the Church.
2 Th 2:15: So then, brothers and sisters, stand firm and hold fast to the traditions that you were taught by us, either by word of mouth or by our letter.
Act 2:42: They devoted themselves to the apostles’ teaching and fellowship, to the breaking of bread and the prayers.
The Epiphany & Trinity
Matt 3:13-17: Then Jesus came from Galilee to John at the Jordan, to be baptized by him. John would have prevented him, saying, ‘I need to be baptized by you, and do you come to me?’ But Jesus answered him, ‘Let it be so now; for it is proper for us in this way to fulfil all righteousness.’ Then he consented. And when Jesus had been baptized, just as he came up from the water, suddenly the heavens were opened to him and he saw the Spirit of God descending like a dove and alighting on him. And a voice from heaven said, ‘This is my Son, the Beloved, with whom I am well pleased.’ (See also, Mark 1:9-11 & Luke 3:21-22)
Let the same mind be in you that was in Christ Jesus,
who, though he was in the form of God,
did not regard equality with God
as something to be exploited,
but emptied himself,
taking the form of a slave,
being born in human likeness.
And being found in human form,
he humbled himself
and became obedient to the point of death—
even death on a cross.
Therefore God also highly exalted him
and gave him the name
that is above every name,
so that at the name of Jesus
every knee should bend,
in heaven and on earth and under the earth,
and every tongue should confess
that Jesus Christ is Lord,
to the glory of God the Father.
1 Jn 1:2-3: His life was revealed, and we have seen it and testify to it, and declare to you the eternal life that was with the Father and was revealed to us— we declare to you what we have seen and heard so that you also may have fellowship with us; and truly our fellowship is with the Father and with his Son Jesus Christ
Ephesians 2:18: for through him both of us have access in one Spirit to the Father.
Col 1:15: He is the image of the invisible God, the firstborn of all creation;
Heb 1:1-4:Long ago God spoke to our ancestors in many and various ways by the prophets, 2but in these last days he has spoken to us by a Son, whom he appointed heir of all things, through whom he also created the worlds. 3He is the reflection of God’s glory and the exact imprint of God’s very being, and he sustains all things by his powerful word. When he had made purification for sins, he sat down at the right hand of the Majesty on high, 4having become as much superior to angels as the name he has inherited is more excellent than theirs.
John 3:34: He whom God has sent speaks the words of God, for he gives the Spirit without measure.
John 17:4: I glorified you on earth by finishing the work that you gave me to do.
2 Cor 1:20: For in him every one of God’s promises is a ‘Yes.’ For this reason it is through him that we say the ‘Amen’, to the glory of God.
2 Cor 3:17-18, 4:4-6: Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. And all of us, with unveiled faces, seeing the glory of the Lord as though reflected in a mirror, are being transformed into the same image from one degree of glory to another; for this comes from the Lord, the Spirit. I n their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God. For we do not proclaim ourselves; we proclaim Jesus Christ as Lord and ourselves as your slaves for Jesus’ sake. For it is the God who said, ‘Let light shine out of darkness’, who has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.
Ignatius of Antioch (112): There is one physican, fleshly and spiritual, begotten and unbegotten, God in Man, true life in death, both of Mary and of God, first passable then impassible, Jesus Christ (Incarnation)
Clement of Rome (100): The Apostles for our sakes received the gospel from the Lord Jesus Christ; Jesus Christ was sent from God. Christ then is from God, and the Apostles from Christ . . . and through the Spirit they appointed their first fruits to be bishops and deacons [overseers and ministers] of them that should believe.
The Vincentian Canon (Catholicity)
Vincent of Lerins (434): Now, in the Catholic Church itself we take greatest care to hold that which has been believed everywhere, always, and by all. One must compare the opinions of the Fathers and inquire of their meaning, provided always that, though they belonged to diverse times and places, they yet continued steadfast in the faith and communion of the one Catholic Church.
Priestly's work omits all these passages, in what can only be considered "selective" reading. The Baptism of Jesus is the Epiphany of his Divine-Human Sonship, testified by both the Father and the Holy Spirit, and becomes the Theophany of the Trinity. After Easter, the Feast of the Epiphany is the second oldest and most important feast of the Christian Church. As Jesus commands, "Go therefore and make disciples of all nations, baptizing them in the Name of the Father, and of the Son, and of the Holy Spirit" (Mt 28:19). The Council of Chalcedon (451) defined de fide the dual natures of Jesus. In long, Priestly is the corruption.
