Don't be silly...I never said every Christian carried a bible in 800 A.D....How many "Heretics" were there up thru the 16 century (that didn't get murdered)??? And how did the heretics get saved??? By 'hearing' the word...They didn't for the most part have to be literate...I have no idea how many there were but they had well over 1000 years to copy manuscripts as fast as they could...And many of them survived to this day...
Gal 3:5 He therefore that ministereth to you the Spirit, and worketh miracles among you, doeth he it by the works of the law, or by the hearing of faith?
Gal 3:2 This only would I learn of you, Received ye the Spirit by the works of the law, or by the hearing of faith?
Rom 10:17 So then faith cometh by hearing, and hearing by the word of God.
Thanks for the nonanswer.
