Mark 16:1-8 is in EVERY Greek manuscript. Maybe a word different or a spelling of a word, but 99.99% full agreement in EVERY Greek manuscript. Then crunch time. The ending (Mark 16:9-20) is found in hundreds of Greek manuscripts and NO TWO AGREE. Some have just another verse. Some have vss 9-13. Others have selections from the verses. Still others have added material not in the AV 16:9-20 at all. Why is this? Because Mark's account ended at v.8 and that is NOT LIKE Matthew or Luke. It kind of just stops. Remember, Mark was writing a sermon preached by Peter . . and this might be where the altar call came in!! So over time, many readers and copyists added their own ending, the ending they heard from others, etc etc and we end up with a huge hodge-podge of endings. It just didn't seem right to not have Mark end like Matthew or Luke. The Byzantine family (copies of copies of copies) had 9-20 added, so it came down as such in the AV. And, of course, the doctrinal mess found in these verses has plagued the church with false groups - from believe and be baptized Campbellites to Appalachian snake handlers. Conclusion: When MAN adds his own ending to the Gospel story, he will pay for it.
