It is actually not the case that Jesus, peace be upon him, is the one and only Son of God, as there are many Sons of God according to the Bible:
The angels are Sons of God:
“Now there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them” [Job 1:6]
As is Adam:
“Which was the son of Enos, which was the son of Seth, which was the son of Adam, which was the son of God” [Luke 3:38]
In fact just about any pious person is a son of God:
“For as many as are led by the Spirit of God, they are the sons of God” [Romans 8:14]
Jesus calls all peace makers the children of God:
“Blessed are the peacemakers: for they shall be called the children of God” [Matthew 5:9]
Here Jesus tells us that we all have the same father:
Jesus said, “Do not hold on to me, for I have not yet returned to the Father. Go instead to my brothers and tell them, ‘I am returning to my Father and your Father, to my God and your God'” [John 20:17]
Therefore it is reasonable to conclude that the term “Son of God” was not meant literally but rather is a metaphorical title. Such language is just the way that the people used to speak back in the days of Jesus.
