Technically, in the book of: Isaiah 7V14:"Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and he shall call his name Immanuel." Isaiah 9 V6:"For unto us a CHILD is BORN, unto us a Son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counselor, The mighty God, The everlasting Father, The Prince of Peace." The Gift-Child in this passage is the same divine Child as Immanuel.. As for the Gospel writers.
OOPS wrote the gospel in after read your instructions--decided to leave it in--apologies. I would say the Holy Spirit announces to Mary that she would give birth to the Christ child--should be touted as the first official mention of this--- Matthew 1V23:"BEHOLD, a VIRGIN SHALL BE WITH CHILD, AND SHALL BRING FORTH A SON, AND THEY SHALL CALL HIS NAME IMMANUEL, which being interpreted is. God with us."
V25:"And knew her not till she had brought forth her first-born son: and he called his name JESUS. Matt 2V1:"NOW when Jesus was born in Bethelehem of Judea in the days of Herod the King, behold, there came wise men from the east to Jerusalem V2:"Saying, Where is he that is born King of the Jews? For we have seen his star in the east, and are come to worship him."
Then in Luke's Gospel. Luke 2V10:"And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. V11:"For unto you is born this day in the city of David a Saviour, which is Christ the Lord.
Mary was close to Luke with his gospel, Peter helped Mark , John Looked after Mary by taking her into his home.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
