“The Bible is complete.”
Uh oh. Which Bible? Which version? The Catholic Bible has extra chapters in it. What about that?
Which version?? If you are familiar with the Greek/Hebrew/Aramaic then you know that almost all modern English translations are acceptable.
I do not accept the Apocrypha as canon, mostly for authorship reasons, however I do see that the can be edifying reading and I have done several studies of them.
There is no need for ‘extra’ scripture.
The Bible is complete for matters of faith and doctrine and to imply or state that God could not preserve His word like He promises in the Bible by allowing errors to creep in is in effect stating that God is weak and not omnipotent.
