Why isn't this in the bible?

IDK, it would fit with all the other fictional bible stuff

Others have posted the equivalent of this answer but there is a particular perspective I want to convey.

Those who accepted Christ's message followed His teachings for nearly 60 years before there was even the first written account that is now in the New Testament.

It was these followers, the early Church, who decided what ought to be memorialized in writing for later generations. Many things were left out, both things from about the same time as Christ, to things that came along many years later.

The process is believed to have taken place under the guidance of the Holy Spirit to such a degree that the New Testament (as the Old) is viewed as being the inspired word of God.

The Gospel of Judas didn't make the cut. Humans who knew the facts about Jesus, prompted by the Spirit, left it where it was when it appeared, namely outside the Scriptures.

Because it wasn't written by Judas. It was written about a century too late, by a cult that is warned about in 1 John. That goes for all the other Gnostic texts as well.

Because the Council of Nicea in AD325 determined that it wasn't credible enough. They could not come close to determining the true author, for starters.

In the Bible, they chose to put in the most seemingly important books, and left others out.

come on now, it's a wiki source. tisk tisk..........

good to stay clear of that sight, no respondent accountability

well, out of the books they HAD at the time, they chose the ones that fit their agenda, and out of those that they did NOT have a copy of, they couldn't rule on

Dubious authorship and non-canonical in nature

Because Judas hung himself, and could not possibly have wrote it. False Gospels were written. They were weeded out, and that is why they do not appear.

its dubious in authorship...was made after 100AD

and has questionable content contrary to the core

beliefs of the bible...

because Christian's don't want the truth...they RUN from the truth.
