I was interested in your interpretation of Mark 16:15-18 Christ's commission to the Eleven.
15 And he said unto them, Go ye into all the world, and preach the Gospel to every creature.
16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
17 And these signs shall follow those who believe: In my name shall they cast out demons; they shall speak with new tongues;
18 They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.
Most Bibles will have a note at the end of verse 8 which reads something to the effect that the following verses (9-20) are not found in the earliest manuscripts of Mark.
Either Mark ended at 16:8 or there is an alternate ending which was lost almost immediately. As a result, I don't worry about these verses as they seem to have been added after the fact. Probably by a well-meaning person but probably after the fact.
