The Biblical Canon was directed by God IN ETHIOPIA.
When James Bruce returned to Scotland from Ethiopia with a copy of the complete Book of Enoch, it was the biggest news for Churchmen in ages! but it didn't change the Presbyterian Canon. A change in Canon necessarily involves an admission of not having had the whole truth. The biggest challenge for any Organized Religion is for it to admit it was wrong about anything. Who wants to pay their tithes to a Sorry Chirch?
