We accept stuff in Scripture as God’s word is Truth.
We do not accept the claims, imaginings, fantasies, and wishful thinking of men who claim things that are not found there.
A question - why?
Why do you accept only those books in the Bible as scripture? What about the fact that the book of the Apocalypse was debated about for so long?
Also in the first century the only commonly accepted books by all Christians, from Anglia to Kodungallur were the 4 Gospels + most (but not all) of the Pauline Epistles (among the New Testament). Even among the Old Testament that was in flux which is why the Syriacs of Southern India and the Ethiopians have additional books as part of their scripture
Why do YOU consider what books you have in your collection of holy books (the Bible) as complete and that :
1. they are holy
2. there aren't others.?
