Again, a forgery. Some manuscripts do not have Son of God. Statements in a Scripture, must be consistent.Does Jesus in fact say that He is Gods Son, not just infer it?
John the Baptist said the same thing (John 1:34).
So, why did Jesus not tell him as he had said to Peter that it was the Father who had revealed, not the flesh and blood?Nathanael said it (John 1:49).
By the way, it was not the Father , who had revealed to Peter. It was Peter' brother Andrew.
Read John 1:41 The first thing Andrew did was to find his brother Simon and tell him,We have found the Messiah(that is, the Christ). 42 And he brought him to Jesus.
No Son of God in there!
And read this from John 1: "45 Philip found Nathanael and told him,We have found the one Moses wrote about in the Law, and about whom the prophets also wroteJesus of Nazareth, the son of Joseph.
