Interesting thread started by a person who may well have been through many of the following thought processes that have pervaded much of my own pathway.
If God intended 'post Christ' mankind to be text book led (as had been the Mediterranean Abrahamic descendants) then:
1) Would he have waited 3-4 centuries, and then used post apostolic religious and secular dignitaries to determine what should comprise the authoritative canon of an extension of what we call the 'Old Testament'?
2) Is there not significance in the fact that Christ himself never committed a single word to writing?
3) Would not God have ensured the preservation of at least most (if not all) of the original 'New Testament' manuscripts?
4) Would God have overseen the production of a new 'Text Book Extension' that was so prone to arbitrary interpretation as to have led to thousands upon thousands of "Only we have seen the light" sects, cults, and denominations?
5) Would God really have 'authored' a theory such as that whereby inhabitants of distant parts of our universe would be condemned to eternal torment in Hellfire simply because they had never seen a 'Bible' or heard and accepted what we call the Gospel Message of Christ and his sacrificial salvation?
6) Etc.,etc., (I could write a book based on such questions).
HOWEVER, my perceived faith eventually had to conclude that:
a) God really is GOD in an absolute and sovereign sense that transcends man's comprehension.
b) Christ became incarnate for the purpose of exemplifying God to mankind, explaining the 'Kingdom of Heaven', and atoning for the entirety of mankind's inherent sin (past, present, and future).
c) The real 'Word of God' is hidden like a treasure, and is to be found by rightfully dividing the written and spoken 'words of man'.
d) Notwithstanding words which appear to suggest otherwise, the efficiency of Christ's atonement for sin, is not dependant on prior knowledge and acceptance.
e) God allowed and allows 'man' to "Create God in man's various imaginations", including such religions, denominations, writings, creeds, etc., as were necessary to ensure the perpetuation of 'faith' throughout the ravages of the 'Dark Ages', the 'Age of Enlightenment', the 'Reformation', and the denominational explosion that followed the Reformation.
f) There will be a Resurrection, the hope of which ensures that 'Faith' has its fulfilment.
