Oh, I see you've changed it. Catholics are finally getting that Jesus DID tell people to write things down.
We don't need to know everything Jesus did or said.
But the Holy spirit made sure that everything we need to know for salvation and being made mature and complete in Christ was included in Scripture.
And; if they forgot; an ANGEL was sent to John to Write to the churches (Catholics were the ONLY kind; remember?) about the ERRORs that they were propagating.
