It always looked so weird to me, like, who not just read the Bible like a proper book instead of having all of those numbering?
I guess it’s because it makes easy to find some specific line? But that is from an academic perspective instead of something you would put in a faith book?
When did that started and why they put all the numbering?
1560 Genevra. Before that, only the chapters were numbered. Probably a consequence of Protestantism, but even Catholic bibles adopted it.
It's still helpful, even nowadays. For example if I told you to find in Sermones the quote at 1.2.69-71 (1st book, 2nd part, lines 69 to 71), you could easily do it. Note how the numbering system is similar in spirit to the one in the Bible - except that the books get an abbreviation instead of a number.
