Wonderful history of how the Lord preserved His Word for us.  Longish video, can be watched in segments.  Many have seen this movie, including the Jesuits, who produced their own “expose” of this in- depth and reverent telling of the saga.  Highly recommended.  Worth watching again and again. 

Psalm 119:159-160

¹⁵⁹ Consider how I love Thy precepts: quicken me, O Lord, according to Thy lovingkindness.

¹⁶⁰ Thy word is true from the beginning: and every one of Thy righteous judgments endureth for ever.
