Nag Hammadi is one of the treasure troves of early Christian writing.
Perhaps...but most of the writings are not Canon and should not be treated as such.
They are very much related to Gnosticism, and therefore, interesting in an historic sense, but not as doctrine.
Even the Dead Sea Scrolls also have texts that are either Apocalyptic in nature, or didactic, or even “Community Rules”, which are ALL fascinating, but are not the same as Scripture.
My comment was based upon the OP, which touts these as a “New” discovery.
