For to which of the angels did God ever say, “You are my son! Today I have fathered you”? And in another place he says, “I will be his father and he will be my son.”
He said to me, ‘Solomon your son is the one who will build my temple and my courts, for I have chosen him to become my son and I will become his father.
that this promise God has fulfilled to us, their children, by raising Jesus, as also it is written in the second psalm, ‘You are my Son; today I have fathered you.’
So also Christ did not glorify himself in becoming high priest, but the one who glorified him was God, who said to him, “You are my Son! Today I have fathered you,”
