In Revelation 22:18-19 we are warned that no man should add to or take away what is written.
"And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book".
Its so much easier and quicker these day to research just about anything. Long gone are the days of swatting for hours in libraries, were as nowadays just click of a mouse will do the heavy lifting for you with reasonably good results.
So can I suggest that you click yours and lets see if that stern warning was adhered to by the Gospel writers or the Church leaders and followers of the church ?
Well right off the bat we can seen that the resurrection storey in Mark was a much later "added to" and there is not a single biblical scholar that will deny this.
What was or "taken away from" John's gospel? Well only the immaculate conception and birth of Jesus - king of the Jews - the Messiah, lord and saviour of all mankind himself.
If we research extrabiblical theological material we can find that the raising of Lazarus from the dead back to life is also an addition.
