But rejected apocryphal books,as did Mary others until Trent provided the first indisputable canon for RCs - after the death of Luther.
Because they didn't transcribe into text everything they were teaching by word and example. Nor did they even write down everything Our Lord taught by word and example. St. John answers the question nicely: John 21:25 "And there are also many other things which Jesus did, the which, if they should be written [not form] every one, I suppose that even the world itself could not contain the books that should be written. Amen."
Which simply does not mean that there is another body of wholly inspired Truth to be proclaimed by Rome under her the novel and unScriptural premise of ensured perpetual magisterial infallibility as per Rome (for which she invokes Tradition). And which is contrary to premise that writing was God means of continued preservation, and which contains, in its formal and material sense combined, what is needed.
St. John speaks to this issue nicely
And many other signs truly did Jesus in the presence of his disciples, which are not written in this book: 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 20:30-31)
