Don't know if any of the words or actions attributed to Jesus are legit. The Bible alone is not a credible source
Here's some verses that have been the reason why some Christians handle snakes and drink poison.
Mark 16 [The earliest manuscripts and some other ancient witnesses do not have verses 9–20.]
9 When Jesus rose early on the first day of the week, he appeared first to Mary Magdalene, out of whom he had driven seven demons. 10 She went and told those who had been with him and who were mourning and weeping. 11 When they heard that Jesus was alive and that she had seen him, they did not believe it.
12 Afterward Jesus appeared in a different form to two of them while they were walking in the country. 13 These returned and reported it to the rest; but they did not believe them either.
14 Later Jesus appeared to the Eleven as they were eating; he rebuked them for their lack of faith and their stubborn refusal to believe those who had seen him after he had risen.
15 He said to them, “Go into all the world and preach the gospel to all creation. 16 Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. 17 And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues; 18 they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well.”
19 After the Lord Jesus had spoken to them, he was taken up into heaven and he sat at the right hand of God. 20 Then the disciples went out and preached everywhere, and the Lord worked with them and confirmed his word by the signs that accompanied it.
Here's an article about the
snake handling Christians...
The recent death of a Christian minister from West Virginia who believed that the Bible instructs the faithful to handle snakes and drink poison has put into question a doctrine many believe is unbiblical and dangerous but that its adherents, biblical literalists, say they are compelled to obey.
To outsiders, mainstream Christians included, snake handling seems foolhardy at best and deadly at worst. And despite commending their desire to be obedient to Scripture, Christians have argued that snake handlers are wrong to take Jesus' words in Mark 16:17-18 literally...
Mark Randall "Mack" Wolford, pastor of House of the Lord Jesus in Matoaka, was passionate about handling snakes during worship services and, according to what the Pentecostal leader told The Washington Post last year, might have drunk two gallons of strychnine – a strong poison commonly used as pesticide to kill rats. If not strychnine, some snake-handling churches keep a flask of carbolic acid at the altar instead.
Wolford, 44,
died May 27, about eight hours after being bitten by one of his poisonous yellow timber rattlesnakes during an outdoor Sunday service at a wildlife park about 60 miles from the House of the Lord Jesus church, where his funeral was held this past Saturday.
Despite his agonizing death – Wolford had refused medical help, choosing to battle the venomous attack from home as he had done many times before – and the similar death of his serpent-handling father nearly 30 years ago, Wolford's mother indicated to The Washington Post that her faith had not been shaken.
"It's still the Word, and I want to go on doing what the Word says," Vicie Hicks Haywood told the publication days after witnessing her son's death.
The "word" that Haywood and dozens of other small Signs Following Holiness congregations primarily in Appalachian states stand on is found in the King James Version of Mark 16:17-18.
Jesus, instructing his disciples to preach the Good News to the world, tells them what signs will accompany those who believe: "... In my name shall they cast out devils; they shall speak with new tongues; 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."
A belief in divine power and healing, including speaking in tongues, or unknown or foreign languages, is not uncommon to Christians. But the Signs Following community is unique when it comes to an interpretation of this passage in Mark, which some scholars doubt was included in the original Gospel account.
In the article it also quoted a pastor saying...
Greg Laurie, senior pastor of Harvest Christian Fellowship in Riverside, Calif., suggested in a Facebook response to a reader doubtful that God "would agree with this practice," that the passage in Mark is to be interpreted spiritually and not literally...
Now that is interesting. So, we have a passage that is questionable about its authenticity. But the rest of what Mark and the other gospel writers wrote is unquestionably true? But if these verses are true, they shouldn't be taken literally? And why is that? Could it be because it doesn't make sense and would be stupid to follow what it says? But the rest of the NT does make sense and should be believed and followed without any doubt?
So, who are the more "authentic" Christians? The ones that take everything absolutely literally? Or the ones that use their brains and get a more reasoned interpretation of the things written in the gospels? I think there are some Christians who will say the "authentic" ones are the ones that believe like they do.
