I found this argument on a thread.
There are two versions of the Gospel of Mark. Short ending and Long Ending.
Scholars know the long ending was tacked on to the end of the original as the short ending has no post resurrection appearances nor the Grand Commission.
Remember what ”Jesus” said in the long version?
Here we go …
“These signs will accompany those who have believed : in My name they will cast out demons, they will speak with new tongues ; 18 they will pick up serpents, and if they drink any deadly poison, it will not hurt them; they will lay hands on the sick, and they will recover .” 19 So then, when the Lord Jesus had spoken to them, He was received up into heaven and sat down at the right hand of God.
Now we all know scholars consider this a forgery – or by now you should know – and it is important to bear this in mind when it comes to Paul whose letters are claimed to precede the gospels tales.
Corinthians is claimed to be a genuine Pauline letter , even though it has some problems of its own – namely 14:34–35, which is said to be a later insertion – interpolation – in other words, a forgery, although, like so much of Holy Scripture(sic) it is hotly debated. Some people simply really want to believe, I suppose.
Here’s the important part of Corinthians for this post.
1 Corinthians 14:18 NAS
”I thank God, I speak in tongues more than you all.”
In the gospel of Mark, the Commission by Jesus predates Paul’s Talking in Tongues.
The Pauline Corpus is based on stories of Jesus after the short Mark was composed.
Do you see the problem?
Acts 28 NAS
3 But when Paul had gathered a bundle of sticks and laid them on the fire, a viper came out because of the heat and fastened itself on his hand. 4 When the natives saw the creature hanging from his hand, they began saying to one another, “Undoubtedly this man is a murderer, and though he has been saved from the sea, justice has not allowed him to live.” 5 However he shook the creature off into the fire and suffered no harm.
Just a thought ….
Here’s a link to the thread. There are some interesting points raised and lots of info.
