In a highly illiterate world, within which there was often no written language for the hundreds of regional dialects, there was no practical demand for a printed vernacular Bible outside of universities, monasteries, and churches. What few vernacular bibles that existed before the printing presses were produced by the Catholic Church. Those that cropped up outside the Church did not receive the Church's seal of approval and the Church rightly it known to all that the content was at least suspect and often heretical.
In its place was religious art depicting scenes, characters, and stories from the Bible. This art, paintings, stained glass, tapestries, sculpture, icons, music and poetry, taught and inspired many generations and provided a necessary mnemonic to the illiterate masses.
Tragically, much of this unprinted Word of God was destroyed by the reformation in its efforts to undermine the Magisterium, re-brand Christianity and control the hearts and minds of the masses (and the wealth of the Church). This was by far a greater hate crime against God and humanity than any measures taken to preserve the orthodoxy of the Word against heresy.
Peace be with you
No sir, the icons & art were/are not in fact the "unprinted Word of God". They were nothing more than images of errant fanciful thoughts and downright pagan idols. The world is far better off with those errors destroyed.
And perhaps you view the past as a "highly illiterate world", but the fact is that copies of the NT letters, together with the Hebrew texts, existed and were read & circulated in nearly every city of the known world. Your organization survives on an imaginary preeminence the way the emperor who had no clothes pictured his regal robes. We invite you to experience a "reformation moment" and come out of this cultish den into the light of Jesus Christ, alone...if you are permitted.
