As it turns out though, this story was not originally in the Gospel of John or any of the other original Gospels. It is not found in any of the earliest surviving manuscripts, it is not in the two 3rd century papyrus witnesses to John (P66 and P75) nor is it in the 4th century Codex Sinaiticus or Codex Vaticanus. The writing style is also very different from what is found in the rest of John and includes a large number of words and phrases that are alien to the gospel. The story was actually added and snuck into the Bible some time during the late 4th century or early 5th century to make Jesus and the Bible appear more appealing.
Mark 16:9-20 where Jesus ascends bodily to heaven is not in the earlier scriptures but rather was added later. None of the earliest scriptures that we have such as the Alexandrian Unical Mss, Vaticanus, and Sinaiticus have versus 9-20, they all just end at 16:8. Also early Christian writers noted that the ascension was not in the earliest manuscripts. Jerome and Eusebius both state that the best manuscripts available to them did not contain the extended ending. Also there are significant linguistic and stylistic differences between 9-20 and the rest of Mark. As noted on page 103 of “An Introduction to the New Testament” by new testament scholar Douglas J. Moo, the longer ending also contains several non-Markan words and expressions.
John 5:7 – “The impotent man answered him, Sir, I have no man, when the water is troubled, to put me into the pool: but while I am coming, another steppeth down before me.”
John 8:7 – “So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.”
John 8:11 – “She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more.”
Luke 24:12 – “Then arose Peter, and ran unto the sepulchre; and stooping down, he beheld the linen clothes laid by themselves, and departed, wondering in himself at that which was come to pass.”
Luke 22:20 – “Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.”
Luke 22:44 – “And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground.”
Luke 24:51 – “And it came to pass, while he blessed them, he was parted from them, and carried up into heaven.”
Mark 16:9-20 – “When Jesus rose early on the first day of the week, he appeared first to Mary Magdalene, out of whom he had driven seven demons. She went and told those who had been with him and who were mourning and weeping. When they heard that Jesus was alive and that she had seen him, they did not believe it. Afterward Jesus appeared in a different form to two of them while they were walking in the country. These returned and reported it to the rest; but they did not believe them either. Later Jesus appeared to the Eleven as they were eating; he rebuked them for their lack of faith and their stubborn refusal to believe those who had seen him after he had risen. He said to them, “Go into all the world and preach the good news to all creation. Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues; they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well.” After the Lord Jesus had spoken to them, he was taken up into heaven and he sat at the right hand of God. Then the disciples went out and preached everywhere, and the Lord worked with them and confirmed his word by the signs that accompanied it.”
