The movable type printing press was invented during the fifteenth century by a German Roman Catholic named Johann Gutenberg.He died a couple of decades before Luther was born.The Gutenberg Bible is reportedly the first major work printed in the West(about 1454).
A significant percentage of folks in Western Europe could not then read. Bible Book Stores did not make their appearance til the 20th century.
Thank you for your help. Could you tell me when the New Testament canon was decided?
