Is that what Catholic priests do??? Why do you leave the rest out that was recorded in Mark???
Mar 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
Mar 16:16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
Mar 16:17 And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
Mar 16:18 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.
Why do you chop up the narrative and take out only what you want???
Do the believing priests (all) cast out devils and speak in new languages??? Do they play with deadly snakes and drink poison??? Why not???
The text says it was made to the eleven.
I did not post to address every possible question. I posted a text only, and tht text was fairly clear who was there when the command was given. Ths snake-handling and poison drinkking is another question, and a good one. But it is not the question of to whom the command was given.
