They did do this very thing! Look at this link:
Early Christian Writings: New Testament, Apocrypha, Gnostics, Church Fathers
Do you understand that there were many false teachings out there? Tons of different writings especially the gnostic ones, perverting the grace of God into sensuality.
But what has survived are the ones that we read and know and agree in our hearts that they write the true grace of God; as Peter spoke of here:
By Silvanus, a faithful brother as I regard him, I have written briefly to you, exhorting and declaring that this is the true grace of God. Stand firm in it. ~1 Peter 5:12
And also John spoke in the same way saying:
Demetrius has received a good testimony from everyone, and from the truth itself. We also add our testimony, and you know that our testimony is true. ~3 John 1:12
Beware of yourself lest this be true of you when Christ spoke this:
Truly, truly, I say to you, we speak of what we know, and bear witness to what we have seen, but you do not receive our testimony. ~John 3:11
And what did he warn you about? Listen here:
Take care then how you hear, for to the one who has, more will be given, and from the one who has not, even what he thinks that he has will be taken away.” ~Luke 8:18
Therefore it depends on you, yourself, whether you block yourself from hearing the truth.
