John, chapter 21
Conclusion. 24It is this disciple who testifies to these things and has
written them,

and we know that his testimony is true.

25There are also many other things that Jesus did, but if these were to be described individually, I do not think the whole world would contain the books that would be written.

Of that there is no doubt.
But he explained in John 20:30-31 what we need and left us with what we have. What more is needed to bring someone into a sustaining relationship with Christ?
30Therefore many other signs Jesus also performed in the presence of the disciples, which are not written in this book; 31but these have been written so that you may believe that Jesus is the Christ, the Son of God; and that believing you may have life in His name. John 20:30-31 NASB
Ok, where in that do you get, “Pray to a dead human who has no power, can’t hear you and never knew you?”
Yet rather than teaching that oral tradition would provide such, John was consistent with writing being the means of preservation, stating,
But these are written , that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name. (John 20:31)
These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God. (1 John 5:13)
Popes do not speak as wholly inspired of God, thus cannot be equal with Scripture
