The usual English ending includes drinking poison and preaching the gospel to every creature (even animals?). The shorter ending is quite abrupt, leaving no resurrection appearances like the other three gospels, only an empty tomb.
So which is it? The Byzantine tradition typically includes the longer ending, which was the Greek picked up by Erasmus and used in early English Bibles, including the King James Version. But the earliest manuscripts, including our earliest Greek Bible called Codex Sinaiticus, do not include the longer ending. In fact, it is some centuries after Mark was written that we first find a longer ending. Those who have researched this in depth typically conclude the evidence favors the shorter ending as the earliest ending.
The question, then, is, “Why was it changed?” As early as the second century, there were attempts by some to harmonize the four Gospels into one. Along the way, those who made copies sometimes, intentionally or unintentionally, made a spot in one gospel match a spot in the other. At some point, this harmonizing likely led someone to add some words to Mark to make the resurrection and Great Commission part sound more like the other three. Once this ending made it into one copy, others found it a nicer wrap up that matched the other gospels. Now, nearly two thousand years, later we’re debating which ending was original.
I’m having a bit of fun here, but don’t for a moment think I don’t believe the Bible is inspired or that it has been corrupted beyond comprehension. This is the biggest “add-on” in the New Testament and one Greek scholars have been aware of for centuries.
This alternative ending of Mark, however, reveals the need for good biblical scholarship even in our time. We must live our faith, but God call us to study, too. This is one example in which diligent study could make a big difference in application.
[By the way, I did write this part out, too, just in case.]
