Christ is risen! He’s risen, indeed! In most modern Bibles, it points out that Mark abruptly ends at 16:8, and two alternate endings, one shorter, and one longer, are tacked on to the end.
This is in fact the longest variant reading in the New Testament. But even this doesn’t change the Gospel at all.
Many anti-Christians like to point out that there are variant readings in the Bible, and pretend that this means that the Bible is unreliable.
And yet, even in this biggest of all variant readings, it doesn’t change the Gospel. Most of the variant readings are just a word here or there, a copying error, etc.
And we haven’t tried to burn and destroy all variant readings, like some other religions. Instead, we have preserved them so one can compare and contrast, and realize that in the end, the Gospel stays the same.
