Working in the religion section of a used book store has taught me one thing clearly. Thousands of christians think that buying a Strong's concordance and looking up key words will teach them waht the bible REALLY means!
Owning a concordance or an interlinear has been the practice of so many bible believers it must be the national pastime!
The fact that most of those books end up being sold to used bookstores tells the tale of how successful this venture really is. (Isn't!)
The language of the bible (Septuagint+Koine Nt) isn't really the FOUNDATION at all.
This is a fallacy.
Knowing Greek or critically studying the texts (thousands of copies) isn't the foundation either.
Discovering that the originals don't exist is the foundation.
A similar problem faces the Koran as well.
Supposedly, Mohammed's closest followers committed the entire Koran to memory!! Then, it was written down by them.
The various bible stories and accounts of "sayings" by Jesus to his followers were NOT WRITTEN DOWN at the time they were spoken!
Some 60 years elapsed between the death of Jesus and the earliest tiny postage-stamp sized fragment of copy of NT manuscript. (Not even an original.)
The bible contains about 776 THOUSAND words.
How many of those words do you think are the EXACT words spoken by the people attributed?
If we don't know the actual and exact words we don't have any way to parse those words and extract meaning.
Learning Greek just isn't the problem.
NOT HAVING THE WORDS (in any language) is the REAL problem for the bible and ultimately for orthodoxy of belief.
