{mosimage}Well, I missed the anniversary by 5 days and I forgot to send a card, but March 22, 1457 (or round abouts) is the first printing date of the Gutenberg Bible – the first Bible printed using movable type. Over at the ESV blog, they published a brief photo survey of printed bibles over time, along with some interesting links to more information.
Interestingly, the ESV blog also devoted another post to why, when & how bibles began to use red letters for the word of Jesus. All due to a man named Louis Klopsch.
