What happened to the gospels that weren't included in the bible?

According to Church historians, early Christians wrote at least twenty gospels that weren't included in the bible. Gospels that were left out of the Bible are called non-canonical gospels. In addition, many church historians also call them apocryphal gospels, because most of them have unknown origins. This uncertainty about their origins was one reason many of them were excluded from the Bible. But some were also excluded because they expressed unorthodox or heretical views.

There are other Gospels such as:

The Gospel of Mary
The Gospel of Peter
The Gospel of Thomas
The Gospel of Judas

Are just a few of the lost gospels.

Don't forget , Pistis Sofia.

They were either run out of town by the pyrotechnicians of the ancient RCC, or they still exist in some hidden forms somewhere. Few have been found, of course, albeit not in good conditions. The christian religion will never be complete until all the other gospels have been recovered in their entirety and made known to the public at large. I bet a lot of them are sitting in the vaults of the Vatican.
