The Son of God was not created but born and nevertheless the Son is not after the Father? Is there significance and an explanation for this belief?

Answer: Please read Chap.5, III, 2 Father-Son. Also: Read Thomas the Apostles profession: My Lord and my God (Jn 20:28)

The offence of the crucifixion was not easy to cope with. The Gospel according to John tells of how the Apostle Thomas, pulled in two directions over doubts on the news of Jesus’s resurrection, fought with himself: Unless I see the mark of the nails in his hands, and put my finger in the mark of the nails and my hand in his side, I will not believe (Jn 20:25). The shock of Good Friday was simply too deep-rooted for Thomas to be able to unquestioningly find his way to believe in Jesus’s resurrection. We have seen the Lord, his fellow Apostles had already told him days earlier. Thomas remained cool and reserved. We have met the Lord, he is alive, they told him. However, he did not trust them. Only the encounter with the resurrected Jesus himself opened the way to belief for the sceptical Apostle: A week later his disciples were again in the house, and Thomas was with them. Jesus came and stood among them and said. Peace be with you. Then he said to Thomas, Put your finger here and see my hands. Reach out your hand and put it in my side. Do not doubt but believe. (Jn 20:26-27). Overwhelmed by this encounter, overwhelmed by Jesus Christ, who lives, Thomas manages to say: My Lord and my God (Jn 20:28). That is some profession! And this profession to Jesus as Lord and as God is at the end of a long road paved with doubts and uncertainties, with misunderstandings and scepticism that Thomas had to journey. And not only him but also all who are followers of Jesus have to take this road to a full understanding of the Lord. After Easter, that is, after Jesus’s resurrection, they recognised him again in the encounter, only then were their eyes opened (see. Lk 24:31). Only then did they have that knowledge of Jesus that then condensed into profession of Him.

In his Letter to the Philippians, Saint Paul quotes a hymn that was composed shortly after Jesus’s death and resurrection, and which summarises the belief in Jesus Christ in this way: He was ….(Phil 2:6-11). This is the fundamental creed of Christianity.
